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:Closed-circuit television monitoring system, video installation set what quotasfixed

In a digital communication system, the transmitted signals are digitized pulse sequences. When these digital signal streams are transmitted between digital switching devices, the rate must be completely consistent so as to ensure the accuracy of the information transmission. This is called synchronization".

Q:Can the closed-circuit line be a monitoring line?

Yes, but the quality of the closed lines, especially the intensity is less, so the life expectancy is shorter and the transmitted signal attenuation is greater.

Q:How to adjust the CCTV screen?

After the computer and television are connected, a screen display operation method is provided:1, in the computer click the right mouse button pop-up menu, select the screen resolution into the settings interface;2, in the resolution settings interface, set the TV set to expand the display;

Q:I'd like to have a closed-circuit monitoring at home

Monitoring requires encoders, decoders, storage, display devices, and so on.If you need to connect to the TV can extract the files, then buy a small hard disk recorder machine, plus a special small camera.

Q:Why is it called closed-circuit television monitoring system? Are there any other TV monitoring systems? For example, open circuit, etc., what is the difference between them?

Closed-circuit television monitoring system is a few years ago to open the wireless television system (wireless television system as long as the signal can receive TV programs, and closed-circuit television (cable) system must be received on the cable system to receive TV programs).

Q:Can the engineering monitor and test instrument measure the closed circuit and the network line?

Yes, you can test the website or video line

Q:How to choose the transmitter in security monitoring system?

APL, that is, the average image level, many engineers are not too careful or not too familiar with this indicator. However, if such a problem encountered in Engineering: when it comes to some video signal through the optical transmission, when a large area of white in the picture (such as camera glare screen) will monitor the level of jitter, so engineers must not strange. This is because the voop some manufacturers of the APL range is too narrow, when there is a large area of white in the image signal, the DC component of each line in the image signal increases, APL will increase, causing the line sync signal amplitude decreased or lost, the monitor cannot detect the line synchronization and screen jitter. If you need to buy otical if the Pacific security network, recommend a few brands pdh.

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

The air conditioning system for a large video monitoring project, monitoring room to install a lot of monitoring equipment and back-end server, and the equipment is expensive, high heat, in order to ensure the normal and stable operation of the equipment, the control room must have air conditioning system, ensure the monitoring center in a state of constant temperature. If there is no air conditioning system, the cooling equipment, monitoring room temperature will rise rapidly, high temperature will cause the device to crash or damage, ultimately affect the entire monitoring system operation.

Q:How to connect the CCTV special monitor power supply?

CCTV (closed-circuit television) has been used in security systems for many years. CCTV is a reliable and economic deterrent, as well as a good evidence of arrest and criminal charges. Now, most security systems need to use several different security technologies, such as alarm systems, fire detection systems, intrusion prevention and detection technologies, access control systems.
