Q:Computer monitors can be used as closed-circuit surveillance TV, only monitors. If you add a converter, you can contact the camera to see the monitor

Want to know the wiring principle it is very simple, is a computer video, the video output is VGA interface, high-definition digital TV or now generally have this interface, according to the line then, if you want the original display can see, you can buy a VGA one minute (general a two can be a) signal is connected with the TV, if no VGA output, can buy a VGA turn lotus head video output converterTwo is audio, with 3.5mm to connect or 3.5mm to Lotus head line, receive the corresponding audio input on TV or sound

Q:About 100 meters of video surveillance, video surveillance video lines can be replaced by closed-circuit TV?

From the structure and performance of the words, the latter will be better than the former, but the current security system or this phenomenon is very strange. So you can directly use this cable to transmit video signals, absolutely no problem.

Q:What is security system engineering, please?

Security system is an emerging professional which has been paid more and more attention. At present, the application of security system is becoming more and more popular and the content of technology is getting higher and higher. Almost all high and new technology can promote its development, especially the advent of the information age, but also to provide an opportunity for the development of the profession. But as far as the monitoring industry is concerned, the system composition has not been clearly divided, which makes communication between the engineering company and the user talking about the security monitoring system very inconvenient.

Q:What is the working principle of TV wall display in security monitoring system?

TV wall display, general use monitors, monitors, television, as well as splicing screen, splicing screen is divided into DLP, PDP, LCD splicing.Analog surveillance generally adopts video matrix, through the BNC interface on the wallDigital monitoring usually adopts digital matrix through the upper wall of VGA interfaceIf splicing screen is adopted, arbitrary splicing can be realized by splicing processor.

Q:What is the difference between "closed-circuit surveillance electronic police" and "electronic police"?

Closed-circuit surveillance electronic police is the camera, monitored by the manual in front of the surveillance screen. "Electronic police" is a camera and sensor matching, illegal activities are automatically triggered records.

Q:How to install closed-circuit monitoring?

Computer monitoring has disadvantages, such as home no one, happen to power outages, after a call, if no one to open the computer, your monitoring system will not run.It is recommended to buy a small video camera, 4 on the road, inside a SATA hard disk, connected to a video camera in front of the house, you can run, can put the picture received on TV, you can watch the AV switch, usually does not affect watching TV

Q:What materials and equipment are needed for complete security monitoring?

TV wall: the main purpose of the TV wall in security video surveillance is to realize the centralized monitoring and management of the whole video surveillance, and the TV wall is the core of the whole monitoring room. Because the client computer relative to the screen size is too small, not easy to watch people at the same time, the TV wall can achieve many people watching the same picture at the same time, but also can be arbitrary switching according to the actual demand
