Dry Goods Sharing: Ten Tips for Correct Choice of Network Video Surveillance System
Video surveillance cameras have become household appliances. Companies of all sizes, from different industries, face the question of how to choose the right video surveillance system. However, because monitoring systems are also constantly updated, software is becoming more and more advanced. The video surveillance system can not only bring security to the business, but if chosen correctly, the video surveillance system can also bring some other benefits that have never been possible before, such as smart detection, big data analysis, traffic, and behavior analysis.
In this article, we have listed ten recommendations for the selection of video surveillance systems.
1. Does the camera have to be hidden or visible and act as a deterrent?
The location of the installation, and the scope of monitoring will determine whether to use ordinary or covert surveillance cameras. Ordinary bolt camera cameras are usually large in size and most prominent after installation. They can remind people that the area is monitored by video and deter criminals, thus reducing opportunities for theft. Hemispherical cameras are the best choice for covert installations, because hemispherical cameras are usually of a small design, so that they are only palm-sized. Finally, the PTZ camera is suitable for a wide range of surveillance and is particularly suitable for office buildings, shopping centers, and parking lots, making it easy to track targets.
2. Is the camera used indoors or outdoors?
Most surveillance cameras are now suitable for indoor and outdoor installations, and some require special considerations such as installation and waterproofing. If you work in extremely cold environments, you must choose a camera to support reliable design when selecting the camera, and a built-in heater to ensure that the camera is turned on at low temperatures and can work properly. If it is applied in the traffic field, then it is necessary to consider the use of reliable and feature-rich video surveillance solutions that can work reliably in extreme environments, even if the installation environment may have vibrations. Cameras that do not support outdoor installation should consider using a protective waterproof case. In other industrial environments such as factories, cameras also need to take dust protection measures. If installed in a restaurant kitchen, make sure that the camera is protected from fumes. This applies to bars, KTVs, etc.
3. What range of cameras need to monitor?
The extent to which a surveillance camera needs to cover determines what type of camera is used. It's best to find a map of the surveillance area and draw a sketch of the camera installation, analyze which cameras you need to use, and how many cameras you will need.
The PTZ dome camera is ideal for wide-range surveillance because the camera can be rotated 360 degrees horizontally, 90 degrees up and down, and supports optical magnification of details. Second, you can use high-definition panoramic camera, panoramic camera can achieve 360-degree video surveillance without blind spots, and supports digital rotary zoom. A panoramic camera can replace up to four traditional surveillance cameras. This means that users can use a smaller number of cameras to set up a network video surveillance system while effectively reducing costs.
In contrast, small-scale monitoring may only require the use of a common surveillance camera. Of course, depending on the scope of monitoring, the network used is different. Most video surveillance only requires the use of a local area network (LAN), while large video surveillance systems will use a wide area network (WAN).
4. What kind of image resolution is required or what kind of detail is required?
The size of the surveillance area will determine how many cameras you need to use. For example, a wide range of applications require the use of a high-definition camera to ensure that the suitability for image magnification does not affect image quality. In addition, smaller areas, such as offices or reception rooms, require only a low-resolution camera. Not a high resolution camera is suitable for all situations. Instead, you'd better evaluate each monitoring point carefully and spend it wisely.
5. How is the ambient lighting condition?
If conditions allow, it is best to test which camera works best under the existing lighting conditions. The light received indoors and outdoors at different times of the day is different, not to mention the changes in each season of the year. It is important to think about where light will come from. For example, will the light reflect from the floor?
Is there a strong background light source and glare? For some environments, such as bars, discos, flashing lights will play a role in the monitoring effect.
Fortunately, there are a variety of different technologies to ensure that the camera captures clear images even under different lighting conditions. Optical filter technology such as infrared cut-off filter can filter unwanted infrared light during the day, thus outputting a true color-reduced color image, relying on an infrared light source at night, the camera can be clearly imaged on a dark night.
6. Do you need to conduct voice monitoring?
Integrated audio capture into the video surveillance system allows security personnel to intercom with the suspect and perform voice monitoring. In terms of video surveillance, it is also possible to implement a separate sound detection function that can trigger recording or alarm. To achieve voice monitoring, the front-end camera must use a built-in microphone and speaker camera, or the camera has an audio input and output interface. Also the back-end recorder or client must be able to connect the microphone and speaker.
7. Does it support extensibility? Over time, do you want to add more cameras to the video surveillance system?
It is very important that the video surveillance system has flexibility and scalability. The traditional closed-circuit monitoring system transmits in the closed circuit, which means that all the equipment must be connected and it is not easy to expand. This is the shortcoming of the analog closed-circuit monitoring system.
It is therefore best to choose a webcam that can add cameras and expand the system over the wireless network. Adding a webcam is as easy as adding a phone to a VOIP network, and it doesn't require changing the line or updating the line.
8. What are the benefits to the business through effective video surveillance?
The benefits of the video surveillance system are not only used to monitor thieves, but also to protect the safety of employees and investigate incidents. Employees know that they are monitored by video and usually feel safer and their work is not lazy.
The video footage provided by the surveillance system can be used to identify incidents such as theft, workplace violence, property damage and damage. This information is indispensable when suing for compensation or law enforcement reporting. However, having a good video surveillance system can bring benefits beyond just security and monitoring, and it can bring more benefits to business operations and analysis.
In some industries, such as retail. The video surveillance system can provide useful data and customer information not only in the security department, but also by marketing, customer service, IT and other departments to provide valuable customer information, thereby greatly improving customer experience and profitability.
For example, the marketing department can rationally arrange the products by sharing and analyzing the movement trajectories of the customers in the stores, and use the video surveillance face recognition technology to classify the customers by age and gender. These features allow shopkeepers not only to better understand their customers' personal data, but also to enable targeted advertising to help display the most relevant products for their target market.
9. What are the difficulties in video surveillance that need to be overcome? Is VMS software analysis useful?
A useful video management system is necessary because security personnel usually watch video for up to 20 minutes. If you use a video management system or built-in video analysis function, it will notify you the first time when a suspicious event occurs, greatly improving the efficiency of video surveillance.
Built-in motion detection and a variety of intelligent algorithms can provide practical, executable information, such as how many people came into the store. In comparison with the turnover, the retailer can evaluate the sales conversion rate at the time of the weekday and holiday promotion.
10. How to choose the right video management system?
First of all, you need to know what requirements you have for the video surveillance management system. For example, how do you intend to use the video management system? Be sure to know before buying. The reason that drives you to purchase a video management system must be that the system meets your requirements for all aspects of the video surveillance system.
If users often travel or have multiple monitoring points to manage, the VMS video management system must be accessible to users anywhere. Each different video management system should provide exclusive customization capabilities for users or applications.
