Recently, many friends have asked about the choice of monitoring systems for stores, supermarkets, and stores, including whether it is necessary to install surveillance cameras? How to choose a suitable surveillance camera? How should Xiaomentou choose a surveillance camera?

Due to the different sizes, locations and installation conditions of various small and medium-sized shops, stores, and stores, it is difficult to have a unified answer. In practice, it is necessary to comprehensively consider factors such as usage scenarios, monitoring scope, and power supply.

This article summarizes some characteristics and needs of shops and shops, and gives some suggestions for some common scenarios, hoping to provide some reference and help for friends when choosing surveillance cameras.

The full text is about 7300 words, and it takes about 6 minutes to read. It is recommended that friends save it for reference at any time.

6. Summary
1. The necessity of installing a monitoring system

For small and medium-sized shops and stores, the role and significance of the monitoring system can be considered from five aspects:

1. Deterrent effect: In many cases, this is the biggest role of surveillance cameras. When the monitoring system is installed, the words “Monitoring has been installed in this store” can be posted at the obvious location such as the entrance of the store. When thieves and other criminals see it, they will naturally carefully consider the cost of crime, which is a good deterrent to criminals.DAHUA NVR5216-16P-4KS2E Dissuasion can also save some unnecessary troubles.

2. Investigation and evidence collection: In the event of lost items, damaged goods, etc., the surveillance video can be retrieved to quickly playback and find abnormal situations, which is convenient for further investigation and evidence collection and reduces financial losses.

 

 

3. Dispute resolution: disputes over cashiers in stores, items forgotten by customers, etc. are very easy to cause disputes. Once such an event occurs, it will have a bad impact on the business. By viewing and retrieving the corresponding surveillance video data, you can easily resolve such disputes.

4. Night care: When there is no one in the store at night, the alarm function of monitoring is activated to monitor the situation of the store in real time. If there is an abnormal situation, it will be notified to the mobile APP in time, DAHUA NVR4208-8P-4KS2/L,DAHUA NVR4216-4KS2/L,DAHUA NVR5216-16P-4KS2E,DAHUA DH-NVR4208-8P-4KS2/L,DAHUA DH-NVR4216-4KS2/L,DAHUA DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L,NVR4216-4KS2/L,NVR5216-16P-4KS2E,DH-NVR4208-8P-4KS2/L,DH-NVR4216-4KS2/L,DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L Price,NVR4216-4KS2/L price,NVR5216-16P-4KS2E price,DH-NVR4208-8P-4KS2/L price,DH-NVR4216-4KS2/L price,DH-NVR5216-16P-4KS2E price and the intrusion of criminals can be prevented in time through the sound and light alarm function.

5. Operation and management: Through monitoring, you can know the business status of the store and the working conditions of the employees at any time, effectively improve the operation efficiency, and enhance the work enthusiasm and work appearance of the employees.

 

 

 

 

To sum up, it is not difficult to see that for small and medium-sized shops, the installation of surveillance cameras has a very positive effect on reducing losses and improving efficiency, so it is very necessary, and the current surveillance cameras are all network cameras, which are easy to install and cheap. Be prepared.
2. Principles of selection of surveillance cameras for small and medium-sized shops and shops

For small and medium-sized shops and stores, due to the consideration of operating costs, the choice of monitoring system is mainly based on high cost performance, and on the basis of economic benefits, try to achieve comprehensive coverage and focus on monitoring.

The monitoring locations that need to be considered usually include: cashier counters, commodity sales areas, customer concentration areas, store periphery/doorway areas, warehousing, and other areas that need to be focused on.

Of course, this is an ideal situation. In practice, we need to comprehensively consider the area, structure, and power supply network of the store.

For example, for small shopping stores or stores, we may only need 1-2 surveillance cameras to fully cover;

For some temporary booths, it is also necessary to consider supporting battery-powered surveillance cameras, etc. I will try to explain them one by one in the introduction of different scenarios later.

For industrial applications, large supermarkets and other places, the design and installation of the monitoring system is much more complicated. It is necessary to comprehensively consider security linkage, network architecture, storage cycle, system security, etc., and a professional design and implementation plan is required.

Third, the selection elements of surveillance cameras

Regarding the introduction of the types and basic parameters of civilian surveillance cameras, I have explained in detail in the article [Indoors] Home Surveillance Camera Selection Guide. If you are interested, you can click for reference.

Here are some factors to consider when choosing a surveillance camera for shops:
1. Shape classification

Surveillance cameras, from the perspective of appearance, mainly include bolts, ball cameras, dome cameras, gimbal cameras, etc. In addition, there are some uncommon types such as fisheye cameras, card cameras, gun balls, and gimbal bolts.

For small and medium-sized shops, the most practical and commonly used types are bolt and dome cameras, both of which are fixed cameras and are more suitable for fixed-range monitoring.

Bolt, named because of its rectangular or cylindrical appearance.
Figure: DAHUA NVR4208-8P-4KS2/L,DAHUA NVR4216-4KS2/L,DAHUA NVR5216-16P-4KS2E,DAHUA DH-NVR4208-8P-4KS2/L,DAHUA DH-NVR4216-4KS2/L,DAHUA DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L,NVR4216-4KS2/L,NVR5216-16P-4KS2E,DH-NVR4208-8P-4KS2/L,DH-NVR4216-4KS2/L,DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L Price,NVR4216-4KS2/L price,NVR5216-16P-4KS2E price,DH-NVR4208-8P-4KS2/L price,DH-NVR4216-4KS2/L price,DH-NVR5216-16P-4KS2E price Common bolt styles

The advantage of the bolt is that the lens selection is more flexible, which can realize both long-distance monitoring and wide-angle monitoring. In addition, the imaging is usually clearer, the night vision function and waterproof and dustproof are also better, and the application range is wider.

Especially for outdoor monitoring, it is more recommended to choose an outdoor camera with a higher waterproof rating.

Hemispherical machines have a hemispherical appearance, and some will be equipped with protective covers.
Figure: Common hemisphere machine styles

The dome machine is usually small in size, more beautiful, and easy to conceal. It is more suitable for ceiling installation in a small area and a relatively fixed location.

There is also a panoramic fisheye camera, which is installed directly above the room. One camera can view the indoor situation in a 360° panoramic view, and one camera can be used as four cameras without missing any pictures.
Figure: Panoramic fisheye camera

 

There are also PTZ machines commonly used in home monitoring. By controlling the PTZ, the camera can be rotated in two directions, horizontal and vertical, so as to achieve horizontal 360° all-round monitoring. Some smart cameras also have automatic tracking and shooting functions.
Figure: Home PTZ

Two-way voice call: Some surveillance cameras support two-way voice intercom function. When an abnormal situation occurs, you can remotely conduct a voice conversation with the scene to solve the problem in time and avoid more losses.
4. Well-known brands and profiles of civilian surveillance cameras

Now the well-known brands in the domestic security industry include Hikvision HIKVISION, Dahua DAHUA, Uniview, Tiandi Weiye Tiandy, Yaan Yaan, Tyco and so on.

Well-known brands of civilian surveillance cameras include: Haikang Fluorite, Dahua Lecheng, TP-Link, Xiaomi, 360, Huawei, etc.

Among them, Hikvision, Dahua, and Pulian TP-Link are relatively common brands in the civilian market, with rich product lines and cameras at different price points.

Usually good brands usually also represent reliable quality and perfect after-sales service. In the following introduction, some models with high cost performance among these well-known brands will also be introduced.
5. Recommendations for cost-effective surveillance cameras in different scenarios

For small and medium-sized shops and stores, due to the different types and sizes of shops, the requirements for surveillance cameras are also different. Here, try to make some analysis and recommendations for some typical and common scenarios.

Different styles of cameras have their own characteristics and suitable scenarios,DAHUA NVR4208-8P-4KS2/L,DAHUA NVR4216-4KS2/L,DAHUA NVR5216-16P-4KS2E,DAHUA DH-NVR4208-8P-4KS2/L,DAHUA DH-NVR4216-4KS2/L,DAHUA DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L,NVR4216-4KS2/L,NVR5216-16P-4KS2E,DH-NVR4208-8P-4KS2/L,DH-NVR4216-4KS2/L,DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L Price,NVR4216-4KS2/L price,NVR5216-16P-4KS2E price,DH-NVR4208-8P-4KS2/L price,DH-NVR4216-4KS2/L price,DH-NVR5216-16P-4KS2E price which need to be considered and selected according to the actual usage scenarios and preferences.
2. Lens focal length

The lens focal length of a surveillance camera determines how wide and how far the camera can see, and is an important factor in our choice of surveillance cameras.

The selection of the focal length of the lens has a complex calculation formula, and the actual parameters of each manufacturer are also different. The selection should be judged according to the actual model.

Generally speaking, the smaller the focal length of the lens, the wider the angle of view, the smaller the visual distance, the larger the focal length, the narrower the angle of view, and the farther you can see. We can make a simple and intuitive reference through the following figure:
The picture comes from the Internet, invaded and deleted

Note: The illumination distance in the figure refers to the distance from which the face can be clearly seen.

For small and medium-sized shops, since the monitoring range is fixed and the area is usually not too large, most of them will choose 2.8mm, 3.6mm, and 4mm lenses, which are enough to see faces in indoor situations.
3. Storage method

 

One of the purposes of installing the surveillance system is to investigate and collect evidence for easy review, which requires the storage of daily recorded videos.

At present, there are three storage methods for surveillance cameras: memory card, hard disk video recorder storage, and cloud storage.

The memory card, usually Micro SD card or TF card, is inserted into the surveillance camera to realize local storage of surveillance video.

It is simple and convenient to use the memory card to store. For a single or less than 4 surveillance cameras, it is recommended to choose this method to save costs.

NVR (Network Video Recorder) storage, that is, network hard disk video recorder storage, realizes the storage and DAHUA NVR4208-8P-4KS2/L,DAHUA NVR4216-4KS2/L,DAHUA NVR5216-16P-4KS2E,DAHUA DH-NVR4208-8P-4KS2/L,DAHUA DH-NVR4216-4KS2/L,DAHUA DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L,NVR4216-4KS2/L,NVR5216-16P-4KS2E,DH-NVR4208-8P-4KS2/L,DH-NVR4216-4KS2/L,DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L Price,NVR4216-4KS2/L price,NVR5216-16P-4KS2E price,DH-NVR4208-8P-4KS2/L price,DH-NVR4216-4KS2/L price,DH-NVR5216-16P-4KS2E price unified management of surveillance video by connecting to the back-end hard disk video recorder. If there are multiple surveillance cameras and the video recording needs to be stored for a long time, it is recommended to choose NVR storage, which can be centrally stored and displayed.

Cloud storage is a network cloud storage service provided by the manufacturer. After opening, the surveillance video files will be synchronized to the cloud in real time through the network. The cloud storage is safe and reliable, and the video recording will not be damaged and not easily lost, which is convenient for subsequent investigation and evidence collection.

For small and medium-sized shops, in order to ensure the safety and reliability of video recording, it is recommended to activate cloud storage services when conditions permit. Cloud storage is usually purchased according to the storage cycle, and different manufacturers charge different fees. The following picture shows the cloud storage charging standard of Hikvision EZVIZ for reference.

Note: The security and stability of cloud storage is related to the image quality of the local camera, network stability, and the stability of the security manufacturer’s server. Each manufacturer may experience incomplete and discontinuous surveillance video. If there is a problem, please contact us in time. Manufacturer’s technical contact solution.

 

4. Waterproof and dustproof

For small and medium-sized shops, it is sometimes necessary to install surveillance cameras at outdoor locations such as doorways, aisles, and corridors. For such scenarios, we need to additionally consider the waterproof and dustproof functions of surveillance cameras.

The waterproof and dustproof of the surveillance camera is usually based on the IP international protection certification level (Ingress Protection), such as IP68. The number behind the IP represents the strength of the protection capability. For details, refer to the following figure:

For outdoor surveillance cameras, at least IP66 or above standards should be met, that is, to ensure complete protection against dust intrusion and to withstand the impact of continuous high-pressure water jets, so as to ensure that outdoor cameras can easily cope with rain and snow weather.
5. Night vision function

The night vision functions of surveillance cameras currently mainly include infrared night vision, starlight night vision, full-color night vision, and black light night vision. For details, please refer to How to choose a home surveillance camera? (Indoor articles) The introduction of night vision function in the article.

The current network surveillance cameras basically have infrared night vision function. When the light is very low, the surveillance camera will activate the infrared light and enter the infrared night vision mode.

In infrared night vision mode, the video picture is black and white, and the distance that infrared night vision can reach from different manufacturers is different, but generally it can reach more than 10 meters.

 

 

If you have higher requirements for night monitoring, you can choose a camera with full-color night vision function. When this type of camera detects extremely low light, it will automatically turn on the white light/soft light fill light, so as to ensure that it can also be used at night. There is a full color screen.

However, the full-color night vision function needs to turn on the fill light, which will generate additional light sources, which needs to be comprehensively considered according to the specific environment.
6. Intelligent function

With the development of technology, more and more intelligent technologies have also been applied to surveillance cameras. For small and medium-sized shops and stores, the following points can be focused on when choosing:

Motion detection: It can intelligently detect whether someone is moving in the monitoring screen, and automatically push the alarm information to the bound mobile APP, which is convenient to check the scene situation at the first time. It is especially useful for night time or when the owner is temporarily away.

Sound and light alarm: When it is detected that a humanoid enters the monitoring area, the sound and light alarm can be linked, and the designated alarm sound is played and the camera flashes a prompt, which can effectively deter theft.

1. The most common choice – monitoring kit

For most stores in the catering, clothing, and retail industries, it is recommended to choose a monitoring suit.

The advantage of the surveillance suit is that it can meet the centralized storage and centralized display of video recordings, and the number of surveillance cameras can be dynamically expanded as needed.

 

 

 

Many supermarkets and medium-sized shops will also be equipped with large-screen monitors to display real-time monitoring images in conspicuous positions, which are convenient for viewing at any time and have a deterrent effect.

The monitoring package usually consists of multiple surveillance cameras, POE switches/POE hard disk recorders, hard disks, monitors, network cables and other equipment. A simple POE monitoring package is composed as follows:

The monitoring kit can choose a monitoring camera that supports hard disk storage, a hard disk video recorder and a hard disk to assemble by itself. The combination is relatively free and the cost will be lower, but it requires certain professional knowledge support.

Personally, it is more recommended to choose a monitoring suit from a professional security manufacturer, which is more reasonable and has higher security and stability.

For most scenarios, when choosing a monitoring package, the following factors can be considered:

✦ Choose a full-color night vision set of 4 million pixels or above, which can ensure that the face can be seen clearly within the monitoring range, and it is still clear after zooming in. The full-color night vision can also provide full-color images at night when needed.

✦ The use of POE hard disk video recorder can not only store surveillance video, but also provide power for POE cameras, eliminating the need for switch equipment and the trouble of installing power supplies for cameras.

 

 

✦ You can choose the bolt and the hemisphere. For the interior of the store, it is usually recommended to choose the hemisphere with 2.8mm and 4mm lenses. Each surveillance camera can cover about 20-30 square meters of space, which is also relatively hidden and beautiful.

✦ It is recommended to choose a camera with a high waterproof rating for outdoor monitoring, which has better waterproof ability and a larger range of focal lengths.

✦ 4-channel DVR can be selected for cameras within 4, 8-channel DVR can be selected for 5-8 cameras, and 16-channel DVR can be selected from 9-16 cameras. The same screen on the computer can support up to 16 different regions of the picture.

At present, the most well-known domestic security manufacturers are Hikvision and Dahua. Based on the above considerations, we recommend the two most practical and cost-effective monitoring kits from Hikvision and Dahua.

Among them, the Hikvision kit lens configuration is higher, and the Dahua kit is more cost-effective. In actual use, it can be adjusted according to the monitoring point and installation position.

● Dahua 4 million day and night full color monitoring equipment set

2. Choice of cost-effective surveillance cameras for small shops and shops

For small shops and stores with an area of ​​20 square meters, a surveillance camera can basically achieve complete coverage of the interior. From a practical point of view, consider the following points when choosing:

✦ More than 2 million pixels to ensure clear images.

✦ 2.8mm – 4mm lens, full coverage guaranteed.

✦ WIFI supply network, reduce wiring and easy installation.

✦ Support motion detection, support two-way voice calls.

✦ Support memory card to store video, reduce cost.

✦ The shape can be selected according to your preference, including bolts, hemispheres, and gimbal.

There are many surveillance cameras that meet the conditions. From the perspective of brand, reputation, quality, and cost-effectiveness, you can choose the following two categories:

 

 

Introduce the POE monitoring kit, its applicable environmental conditions, and why it is better to install POE monitoring. First of all, let’s briefly talk about its suitable areas, such as medium-sized hotels, large warehouses, villas, office buildings, etc., which require video data storage certificates and environments that require high monitoring stability. Installing POE monitoring kits in these areas is safer and less expensive than wireless monitoring.

Take a restaurant as an example. There is a large flow of people in the store every day, and conflicts are more likely to occur. At this time, retrieving surveillance video will become a quick way to solve the problem.

First of all, wireless monitoring is related to the distance of the wifi signal. If the area of ​​the hotel is large, it is very likely that the monitoring on the side has no signal, which makes it impossible to monitor and the data is unstable;

Secondly, wiring is relatively troublesome. Wireless monitoring needs to be connected to wires, which has high requirements for the installation environment, and the lines are complicated and unsafe. Poe uses network cables to transmit data, which is safe and convenient;DAHUA NVR4208-8P-4KS2/L,DAHUA NVR4216-4KS2/L,DAHUA NVR5216-16P-4KS2E,DAHUA DH-NVR4208-8P-4KS2/L,DAHUA DH-NVR4216-4KS2/L,DAHUA DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L,NVR4216-4KS2/L,NVR5216-16P-4KS2E,DH-NVR4208-8P-4KS2/L,DH-NVR4216-4KS2/L,DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L Price,NVR4216-4KS2/L price,NVR5216-16P-4KS2E price,DH-NVR4208-8P-4KS2/L price,DH-NVR4216-4KS2/L price,DH-NVR5216-16P-4KS2E price

Finally, POE monitoring is stored on a hard disk, the data is stored for a long time, and the price is relatively cheap. There are basically two storage methods for wireless monitoring, memory card and cloud service. The storage time of the memory card is short, and the cloud service is expensive. Neither is a good choice.

To sum up, if you install more than 4 cameras, I personally recommend POE kits. You need more equipment in the early stage, and the price may be slightly more expensive, but you basically don’t need to spend money on post-maintenance and data protection.

Some friends may ask that there are so many POE equipment, the installation is complicated, and there are many things to buy, which is too troublesome. In fact, don’t worry about this problem, the POE package already contains all the monitoring equipment, you only need to install it yourself, and there are instructions, it is not difficult.

So how to choose? With so many brands, what should I do if I want to choose a cost-effective POE monitoring kit? The point is here, let me talk about it, it is really difficult for friends who do not understand the monitoring and security industry, but I have a method here, you can refer to it~

First of all, look at the brand rankings of the monitoring industry on the Internet. Although the brand rankings from different evaluation agencies may be different, they are basically the same, and the order may be slightly changed. The top brands have been tested by the market, and the quality, word of mouth, and after-sales are mostly praised.

Second, search the web for monitoring kits to find the ones with the highest sales among the top 10 brands, and those with low sales are automatically skipped. At this time, some of them have been screened out, and then find out from the high-selling monitoring kits that meet your requirements. For example, are there any requirements for night monitoring? If there is a requirement, it is better to choose full-color night vision, and if there is a requirement for image quality, choose a pixel above 300W, and so on. Because the cameras in the POE monitoring kit are different, the functions will also be different.

 

Finally, depending on the price, the most expensive ones are also filtered out. Finally, if you look at the product evaluation, you can basically choose a POE monitoring kit that meets your requirements.

Below, we recommend several POE monitoring kits that meet different environments with comprehensive brand, quality, reputation, evaluation and other factors. You can refer to them if you need them.
The monitoring system is a system that collects video images from a certain area through cameras, and then transmits and stores them by other devices. It can truly reflect the actual situation in the area, and has functions such as real-time display, video recording, and video playback. So what equipment is the monitoring system composed of? And what is the function of each device? Let’s take a brief look at it below.

Why Buy a Camera?

· Security issues: You can check your home situation anytime, anywhere if you are away from home for a long time during the festival and Chinese New Year.

· Yunlu Cat: Cloud cat raising is a must, and you can talk to your cat on your phone at any time (it may ignore you at first, but you won’t get used to it later)

· Watching the elderly and children: There are only the elderly or children at home. You can check whether there is a prominent incident at any time. You can also make remote calls without the need for a phone call. You can also observe the behavior of the babysitter, and whether there are other abnormal behaviors while taking care of the elderly.

· Baby room: If your home is very large, and many children are still small and sleep alone in the baby room, the cry detection function can go upstairs to coax the child at the first time.

▶ Are home cameras expensive?

The general price of home cameras is 100-200 yuan, 200-400 yuan, which is not too expensive and meets the daily needs of most people. But there are also high-end cameras of EZVIZ 6Wi flagship 649 and Dahua Lecheng wireless surveillance camera 699.

In addition to the purchase of memory cards, the price of cloud storage may also be of concern to everyone. It is a special reminder that the prices seen on Android and Apple mobile phones are different. Borrow an Android phone to activate cloud storage, and then use an Apple phone to board it for normal use!

 

 

▶ What size memory card do I need to buy?

Now each brand has its own brand of memory card, but the price is generally a bit more expensive, but they also support SanDisk, Kingston, so you can buy another memory card if you don’t mind the trouble. As for the capacity, it is recommended to buy at least 64G , Because now the camera is generally more than 3 million pixels, if it has H.265 video encoding technology, it can save half of it, 32G can record 2.5 days, 64G can record about 5 days, 128G can record 10 days.
First of all, recommend a good brand, Hikvision camera brand ranking first, with a positive rate of more than 90%! No. 1 in market share! Hikvision’s surveillance cameras have comprehensive functions. This product is designated as the leader of smart homes, and is a network smart product that can watch the captured images at any time through mobile phones. It is understood that the product can not only view the current painting at any time, accurately record the picture, but also play back any recorded clips, and users can conduct real-time intercom through its built-in voice function. The Hikvision surveillance camera can be directly connected to the router. As long as the IP address of the Hikvision surveillance camera and the router are in the same network segment, real-time monitoring can be performed.

4. Summary
1. Selection elements of home outdoor camera

Due to the wide monitoring range, high night vision requirements, and more complex external conditions, outdoor monitoring needs to be more careful when choosing. Here are a few factors that need to be paid attention to:
1. Lens focal length

How far can a surveillance camera see? This is a problem we often encounter when choosing a surveillance camera.

Generally, the effective monitoring distance of a surveillance camera is determined by the focal length of the lens and the illumination angle. There are complex calculation formulas in it, and different manufacturers will obtain slightly different data due to different lens apertures and algorithms. We will not expand them here.

We only need to remember one concept: the larger the focal length of the lens, the farther you can see, the smaller the range of viewing angles, the smaller the focal length, the closer you look, the wider the range of viewing angles.

The following figure can be used as a simple reference:
Note: The picture is from the Internet, invaded and deleted

Note: The illumination distance in the figure refers to the distance at which the face can be clearly seen, and the actual visible distance will be farther.

In addition, some camera lenses are zoomable, and the size of the lens can be adjusted according to the scope of the monitoring scene, which is more flexible and convenient. For the case where there are multiple points to be monitored but only one camera needs to be installed, a zoomable camera can be considered.

The focal length of the lens is an important factor in the selection of an outdoor surveillance camera, and we should carefully consider it according to the situation when choosing.
2. Waterproof and dustproof

 

 

Outdoor monitoring, it is inevitable to face various extreme weather and environments, so waterproof and dustproof are also our priority functions.

Regarding waterproof and dustproof, there is a set of international IP protection level standards.

IP (Ingress Protection) protection level is composed of two numbers, such as IP68, the first number indicates the level of the electrical appliance against dust and foreign objects intrusion, and the second number indicates the degree of airtightness of the electrical appliance against moisture and waterproof immersion. The larger the value, the higher the protection level.

For outdoor cameras, at least ensure that they meet the IP66 standard or above, that is, to ensure complete protection against dust intrusion and withstand continuous high-pressure water column impact, so as to ensure that outdoor cameras are not afraid of wind and rain.

In addition, in industrial applications, factors such as lightning protection, moisture resistance, corrosion resistance, and explosion protection will also be considered. For these needs, professional security manufacturers have corresponding products and solutions. Home monitoring generally does not involve too complicated situations, and you can leave a message to communicate if you need it.

3. Night vision function

Outdoor surveillance usually also has high requirements for night vision. At present, most of the mainstream surveillance cameras in the market support infrared night vision function. On top of this, there are starlight night vision, full color night vision, and black light night vision.

The difference between these night vision functions has been introduced in the indoor article. You can refer to the article for details: [Indoor article] Home surveillance camera purchase elements and cost-effective surveillance camera recommendations in different scenarios.

In order to ensure the night vision effect of outdoor surveillance, it is recommended to choose a surveillance camera that supports starlight night vision or full-color night vision.

Starlight night vision usually uses a large aperture lens and a high-sensitivity sensor, which has more light in, and can still ensure a clear color picture in a low-light environment, but it will automatically turn to black and white when it falls below a certain brightness threshold.

Full-color night vision, when the ambient light is extremely low or even no light, it will automatically turn on the fill light to achieve full-color day and night.

Little knowledge: It is not that full-color night vision is stronger than starlight night vision. These are just two night vision modes for different scenarios. More often, the image quality of cameras that support starlight night vision is better than full-color night vision.

 

 

In addition, there are some enhanced functions, such as some cameras provide 3D digital noise reduction for the situation where the light is insufficient at night and the image noise is not clear; for the case where the light is bright and the contrast is too large, the image background is too bright or the foreground is too dark, Some cameras offer the WDR function.

These enhanced functions can make the monitoring picture more pure, delicate and soft. Under the same configuration, we can give preference to cameras with enhanced functions.
4. Storage method

At present, the storage methods of surveillance cameras mainly include memory card, hard disk video recorder storage, and cloud storage.

There is only one outdoor surveillance camera, and if the recording storage period DAHUA NVR4208-8P-4KS2/L,DAHUA NVR4216-4KS2/L,DAHUA NVR5216-16P-4KS2E,DAHUA DH-NVR4208-8P-4KS2/L,DAHUA DH-NVR4216-4KS2/L,DAHUA DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L,NVR4216-4KS2/L,NVR5216-16P-4KS2E,DH-NVR4208-8P-4KS2/L,DH-NVR4216-4KS2/L,DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L Price,NVR4216-4KS2/L price,NVR5216-16P-4KS2E price,DH-NVR4208-8P-4KS2/L price,DH-NVR4216-4KS2/L price,DH-NVR5216-16P-4KS2E price is not high, it is recommended to choose memory card storage, which is also the most cost-effective storage method.

On the contrary, if the recording storage period is longer, or there are multiple surveillance cameras that need to be stored at the same time, it is recommended to choose a hard disk video recorder for storage.

DVR storage requires separate configuration of DVR and hard disk, and the cost will increase. But in contrast, the storage capacity is much higher, it supports multi-channel camera input, and it is also convenient for centralized storage and centralized viewing.

The storage cycle calculation methods of different manufacturers are also different. The following figure is the hard disk storage cycle reference table provided by Hikvision. We can simply calculate how much storage space we need to purchase based on the camera resolution (number of pixels) and storage cycle.

Cloud storage, almost every manufacturer will provide this service, cloud storage is usually charged according to the storage cycle and usage period, and the cost is relatively high.

However, because the video is stored in the cloud, it is not easy to be damaged, which is convenient for investigation and evidence collection. If the security requirements of video files are high, you can consider using both local storage and cloud storage.

The following picture is the official cloud storage charging method of Hikvision EZVIZ. The pricing of different manufacturers is different. If necessary, you can consult the official customer service or check the purchase directly in the mobile APP.
5. Power supply network mode

At present, there are four main power supply methods for surveillance cameras: power supply, network cable power supply, battery power supply, and solar power supply.

There are three main network supply methods for surveillance cameras: network cable, wireless WIFI, and traffic card.

For outdoor monitoring, power supply and supply network can often be considered together, for example:

 

1. It is not far from the room and it is convenient to pull electricity, such as balconies,nvr5232-16p-4ks2e, indoor courtyards, and surrounding villas, etc., it is recommended to choose a camera with power supply and WIFI network supply.

This method saves the trouble of network wiring. When the WIFI signal is unstable, the WIFI signal amplifier can be used to enhance the WIFI signal, which is simpler and more practical.
Note: The picture is from the Internet, invaded and deleted

2. Some distance from the room, the Wifi signal cannot be covered or the signal is unstable, such as outdoor parking spaces, own gardens, vegetable fields, orchards, etc., you can choose the POE (network cable) power supply method.

Surveillance cameras that support POE power supply can work normally without power supply. The network cable can play the role of power supply and network supply at the same time, which is more suitable for scenarios that require multiple surveillance cameras.

The current ordinary network cable (category 5 cable) has a maximum data signal transmission distance of about 100 meters, which can meet most needs.
Note: The picture is from the Internet, invaded and deleted

3. For some situations where the monitoring range is very wide and it is inconvenient to pull electricity, such as large farms, fish ponds, orchards, etc., you can choose solar + battery power supply, and flow card power supply to achieve monitoring.

However, it should be noted that the solar + battery power supply method is affected by external factors such as environment and weather, and the current technology is not so mature. The cost of this method is relatively high.
Note: The picture is from the Internet, invaded and deleted

In general, the power supply network and power supply mode of outdoor monitoring need to be reasonably matched according to the existing conditions. For some special environments, it is necessary to consider poles, or choose waterproof and anti-corrosion materials.
6. Intelligent function

For outdoor monitoring, in addition to the basic parameters and functions, you can also focus on the following four intelligent functions:

1. Automatic cruise: Outdoor monitoring generally needs to pay attention to a relatively large range. The automatic cruise function can make the camera automatically cruise through a certain sequence and cycle time interval, so as to realize multi-point and large-scale monitoring, especially suitable for orchards, Scenes like farms, fish ponds, etc.

2. Motion detection: Accurately determine whether someone is moving in the monitoring screen,DAHUA NVR4208-8P-4KS2/L,DAHUA NVR4216-4KS2/L,DAHUA NVR5216-16P-4KS2E,DAHUA DH-NVR4208-8P-4KS2/L,DAHUA DH-NVR4216-4KS2/L,DAHUA DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L,NVR4216-4KS2/L,NVR5216-16P-4KS2E,DH-NVR4208-8P-4KS2/L,DH-NVR4216-4KS2/L,DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L Price,NVR4216-4KS2/L price,NVR5216-16P-4KS2E price,DH-NVR4208-8P-4KS2/L price,DH-NVR4216-4KS2/L price,DH-NVR5216-16P-4KS2E price intelligently distinguish invalid and false alarms, making the alarm function more practical, and can be pushed to the bound mobile phone in time.

3. Sound and light early warning: When someone illegally intrudes into the dangerous area, the camera detects the intrusion and can link the sound and light alarm to effectively deter illegal acts.

4. Two-way voice intercom: When an abnormal situation occurs, the local two-way voice intercom function can be used to take fast and effective response measures to various emergencies to avoid losses.

These intelligent functions have greatly improved the practicability of surveillance cameras, and we can also consider them according to actual needs when choosing.
2. Brand and introduction of home outdoor camera

Outdoor monitoring has high requirements on image quality, transmission stability, functions, etc., so it is recommended to choose a professional security brand as much as possible, the product quality is relatively reliable, and after-sales service can also be guaranteed.

3. Analysis and recommendation of outdoor camera application scenarios

Due to the complex and changeable situation faced by household outdoor surveillance, the selection of outdoor surveillance cameras needs to be comprehensively considered according to factors such as monitoring range, night vision requirements, and power supply and network methods.

The following is a brief analysis of some common outdoor monitoring scenarios, and some suitable models are provided for reference.
1. Outdoor courtyard, farmyard

The monitoring requirements of outdoor courtyards and farmyards are relatively simple. The main focus is on the scope of monitoring. Consider the following points:

Nowadays, most of the homes have broadband and Wifi. It is recommended to choose the Wifi connection method, which is convenient for wiring.

✧ Fixed monitoring range and optional outdoor camera, better waterproof night vision;

✧ A wide range of cloud billiard machines can be selected, which can monitor 360°.

✧ Select the 2.8mm-4mm lens within 10 meters of the monitoring radius, and select the 6mm and above lenses.

✧ Waterproof and dustproof choose IP66 or above.

✧ For scenes with larger area, it is necessary to consider installing multiple surveillance cameras to ensure complete coverage.

There are still many types of cameras that meet the needs. I have selected the three most representative surveillance cameras with 4mm focal length, among which:

EZVIZ C8W, equipped with two-way gimbal for 360° monitoring without dead angle, and the best picture quality;

TP-Link dual-camera zoom, supports 9x zoom screen zoom, can take into account the global and key areas;

Dahua Le Orange TF2, IP67 professional waterproof, comprehensive functions, high cost performance.

IP66 waterproof, no fear of wind and rain.
Intelligent humanoid monitoring, active defense, sound and light alarm. Doorways, roads, fixed parking spaces

In this type of scene, the monitoring range is usually clear, but the monitoring distance is relatively high. Therefore, the main focus is on the focal length of the lens and the night vision function. It is recommended to choose a gun with a large focal length of the lens.

The following two outdoor surveillance ipc-hfw3549t1-as-pv cameras have a focal length of more than 6mm, and the infrared night vision distance can reach about 30 meters. Suitable for long and narrow areas, roads and specific targets up to 10 meters away.

3. The surrounding of the villa and the fence

For large and wide-ranging monitoring scenarios such as villas and farmyards, it is recommended to choose a monitoring set.

For villas, the monitoring points need to consider multiple areas such as villa gates, courtyards, walls, garages, and indoor living rooms, balconies, etc., and multiple cameras need to be installed to achieve comprehensive monitoring. Therefore, it is recommended to choose a monitoring package that can support simultaneous access of multiple cameras, unified storage, and unified management.

The monitoring package is generally composed of cameras, switches, video recorders, hard disks, monitors, network cables and other equipment. Some hard disk recorders with POE power supply function can save the switch. A simple system consists of the following:

In the monitoring package, we need to select the corresponding hard disk video recorder according to the number of monitoring points (number of channels) required, and the indoor monitoring camera can also be connected, saving the cost of the camera’s local memory card.

It is recommended to consider professional security manufacturers for the selection of monitoring kits, with more reasonable configuration and better stability. The more well-known ones are Hikvision and Dahua.

The two official monitoring kits from Dahua and Hikvision are selected below. They are both 4-channel 4-megapixel full-color night vision kits with 2T hard drives. They support POE power supply, full-color night vision, and humanoid detection. The quality and storage period can meet most needs.

If there are more monitoring points and complex requirements, you can choose different number of hard disk video recorders and monitoring cameras that support hard disk recording according to actual needs.

For villas, it can also be linked with other security facilities such as access control, detectors, and anti-theft alarms to achieve real comprehensive security.
4. Mobile paving/battery powered

A friend once asked if there are surveillance cameras suitable for outdoor stalls and without power supply. In such scenarios, you need to consider battery-powered surveillance cameras.

Battery-powered surveillance cameras, due to the bottleneck of current battery technology, are difficult to support uninterrupted video recording for too long.

Therefore, intelligent RIP sensing technology is usually used, that is, it will automatically record when a valid living creature is detected, and enter the sleep state to extend the working time when no one is there. We should pay attention to the internal monitoring parameter configuration of the camera when using it.

Here are two surveillance cameras that are suitable for use without power supply. Among them, the EZVIZ BC1 is a fully wireless battery-powered camera with long standby time, and the 360 ​​camera battery version is a dual-power battery-powered camera, suitable for temporary use during power outages.

 

 

EZVIZ BC1 is a new fully wireless battery-powered camera from EZVIZ. It is equipped with a 12900mAh large-capacity lithium battery. According to the official data, it can be used for 365 days with 5 minutes of use a day, and it can be used for at least 24 hours under continuous working conditions.

Intelligent full-color night vision mode, equipped with dual infrared lights and dual warm lights, to ensure colorful images at night.
Intelligent RIP sensor, when it detects the movement of living creatures, it will trigger sensor reminders and video recordings, saving space and power.

It supports dual power supply of battery and power supply. It has a built-in 5000mAh battery and can work normally even in a power outage.
Two-way gimbal, panoramic view.
Intelligent RIP + cloud recognition, double humanoid detection, filtering invalid alarms.
When a humanoid is detected approaching, a sound can be played automatically, which can be an alarm or a customer-receiving sound.

For battery-powered surveillance cameras, the battery life is related to the recording time and the wake-up frequency, which is usually lower than the officially announced battery life, so there should be psychological expectations. In addition, battery-powered cameras are generally not recommended to use both power and battery at the same time.
5. Orchards, farms, fish ponds

For scenarios such as orchards, farms, and fish ponds with a wide range of monitoring and complex power supply conditions, we can consider the following:

Stable power supply, monitoring range within 100 meters

In this case, we can consider using POE-powered monitoring kits. For the selection of kits, please refer to the aforementioned Hikvision and Dahua monitoring kits.

In addition, we can also consider extending the Wifi coverage by means of wireless bridge relay, so that we can still choose wireless WIFI surveillance cameras at a long distance, reducing the trouble of wiring.

 

 

The following TP-Link wireless bridge can extend our wireless Wifi coverage up to 15 kilometers away, which can greatly expand our monitoring range.

TP-Link is the world’s leading supplier of network communication equipment, with reliable quality and rich product lines, you can choose the appropriate wireless bridge according to your needs.
Specially designed for outdoor, the longest transmission can reach 5 kilometers.
No configuration, easy installation, easy transmission of high-definition video.
Be careful not to have any obstructions between the two ends.

Stable power supply, monitoring range beyond 100 meters

In this case, we can choose a surveillance camera that supports traffic card/4G network transmission. In this way, we do not need to consider the factors of network transmission wiring, but the use of traffic cards or mobile phone cards requires consideration of ongoing cost expenditures.

From the perspective of brand DAHUA NVR4208-8P-4KS2/L,DAHUA NVR4216-4KS2/L,DAHUA NVR5216-16P-4KS2E,DAHUA DH-NVR4208-8P-4KS2/L,DAHUA DH-NVR4216-4KS2/L,DAHUA DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L,NVR4216-4KS2/L,NVR5216-16P-4KS2E,DH-NVR4208-8P-4KS2/L,DH-NVR4216-4KS2/L,DH-NVR5216-16P-4KS2E,NVR4208-8P-4KS2/L Price,NVR4216-4KS2/L price,NVR5216-16P-4KS2E price,DH-NVR4208-8P-4KS2/L price,DH-NVR4216-4KS2/L price,DH-NVR5216-16P-4KS2E price and stability, two surveillance cameras that support 4G transmission can be considered:
