Video surveillance is an important part of the security system. It is an integrated system with strong prevention capabilities. Video surveillance is widely used in many occasions for its intuitive, accurate, timely and rich information content. In recent years, with the rapid development of computers, networks, and image processing and transmission technologies, video surveillance technology has also made considerable progress. Now video surveillance has been widely used in various fields, and some families have begun to install monitoring equipment. Did you consider the following ten questions during the installation process?
1. What is the installation of a video surveillance system?
Video surveillance is often installed for a variety of purposes. For some units, the main purpose of video surveillance systems is to protect collective property and reduce property loss. Others focus more on protecting personal safety, such as schools and nurseries, so that parents can rest assured that their children are at school. For home users, their use varies according to their needs. It can be used to protect the safety of family property, but it can also be used to remotely care for the elderly and children. The difference in monitoring objectives and focus directly determines the user’s concern about the convenience of real-time video and access to recorded video content. In addition, if you pay much attention to the function of Internet access, you need to pay special attention to whether the screen resolution can be adjusted according to your needs.
2. What is the type of infrastructure monitored?
There are multiple buildings that need to be monitored? Are they geographically dispersed? If you have multiple buildings, do you want to monitor the targets in different locations? These are issues that must be considered. If you want to centrally monitor the goals of all locations, you also have to consider the type of connection between the goals. The type and location of the infrastructure also affect the location of the camera deployment. If the camera is deployed outside the building, then the building itself requires a special security system. If you want to implement a camera that can adjust the surveillance angle, you need to purchase a PTZ-enabled camera (PanTiltZoom).
PTZ is an abbreviation of Pan/Tilt/Zoom, which represents the pan tilt, zoom, and zoom control of all directions (up and down, left and right). In the scene range monitored by the camera, when the moving target appears, the user can manually lock (for example, the target is locked by a mouse click) or the preset position automatically triggers locking of a moving target to trigger the PTZ camera to perform autonomous automatic PTZ tracking. And automatically control the pan tilt of the PTZ camera to rotate in all directions, and perform a visually guided automatic tracking of the locked moving target to ensure that the tracking target continuously appears in the center of the lens. The automatic PTZ tracking module compensates for the shortcomings of the narrow vision of the fixed camera surveillance and is an essential function of a perfect security monitoring system.
3. What is the type of network connection between buildings and buildings?
There are many optical fiber networks installed in buildings or inside buildings. If this is the case, you may consider using IP cameras or hybrid IP cameras and traditional analog cameras. Although IP cameras are much more expensive than traditional analog cameras, the total cost is still superior.
IP cameras do not require additional wiring and can be easily installed by a network administrator. In addition, the price of IP cameras will gradually decline. If you already have an analog camera, but want to use an IP camera, then you might consider building a hybrid system that supports both cameras.
4. Do you already own tape camcorders based on the VCR system?
If you already have a tape system, then you can make full use of existing cameras and cabling systems, which will save a lot of unnecessary expenses. However, you should also take this opportunity to revisit the number of cameras you use and the location of your deployment. In addition, it depends on whether you install the video surveillance system yourself or through an integrated approach. If you are installing it yourself, you need to understand the structure and wiring of the house. Do you understand the basic cabling and camera deployment locations? If you are not using an IP network, then you need to install the coaxial cable. Community monitoring Even if you do not use IP cameras, you also need to have people who understand the network technology to help you achieve network viewing and recording video content. If you plan to use integrator solutions, have they had success stories similar to yours? How often do the video surveillance installations demonstrated by these successful cases usually last?
5. What are your requirements for picture quality?
Different video surveillance systems can support different resolutions and frames. Resolution is a reference standard for measuring picture quality. The higher the resolution, the higher the picture quality. Frames per second (fps) Description The number of frames (pictures) captured in one second. The higher the fps, the more coherent the recorded picture becomes. High frame rates can often be used to monitor detail-oriented video, such as casinos can use high frame rates.
6. How long do you want to keep the recording?
High resolution and high frame rates require more network bandwidth resources and also occupy more video storage space. How long do you want to keep recorded content? Your system provider or integrator will tell you the approximate requirements for resolution and frame rate, and will therefore tell you how many days of video storage you want to keep. To a certain extent, this has a lot to do with the type of system purchased. Using a PC system can usually be upgraded to get more video storage space.
7. What kind of company is the manufacturer of video surveillance system?
Whether you install video surveillance systems on your own or use integrated systems for installation, you should be concerned with the actual manufacturer of the system. How long are these manufacturers engaged in this field? What type of support can they provide? Many companies are located in Asia, and the support provided is not very rich. For example, if you want to set up a video surveillance system for your school, ask them for reference materials about school applications.
8. What are the strengths of vendors and the rich reference support they provide?
The number of security companies is actually a lot, including both foreign brands such as Sony and Samsung, as well as well-known brands such as Hikvision, Tiandi Albert, and Wave Grain. Hikvision's DS-2CD762MF-FB(H) day and night waterproof and anti-riot dome network cameras, DS-2DF1-7XY series network infrared high-speed intelligent dome cameras and DS-2DF1-57XY network high-definition and high-speed intelligent dome cameras are currently relatively Welcome to the HD surveillance camera. Now, powerful companies not only produce products but also provide solutions based on customers' different needs.
9. Who is responsible for providing technical support for video surveillance systems?
Who provides technical support for your existing IT environment? If you have such support, using a PC computer system will be even more handy. Some manufacturers also provide technical support.
10. What is your budget?
After answering these questions, I now return to understanding system costs and my own budget issues. How much is your budget? Whether to contact a local system integrator or search for a video surveillance manufacturer online. Ask for different vendors and compare their product differences according to your requirements. It should be noted that this is not only a matter of purchase, but also a special consideration of the installation and maintenance of products and systems.
The factors that determine the purchase of a video surveillance system are complex and wasteful. After answering these ten questions, at least one can be sure.
