Q:What are the security monitoring TV walls required?

A network video decoder is needed to board the TV wall. This device does not normally support VGA interface display devices.Ten thousand mast meets this kind of situation, thought that the plan which does not use the television wall is simple, a computer plus a projection may substitute, the cost is also low

Q:Video monitor prices

Prices, monitors, brands, TCL, HIZOR, MYWAY, etc. are expensiveThe second tier brand Tiger clinkstone worried stone and so on the price a little cheaper

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:Characteristics of closed circuit monitoring system

Closed circuit monitoring system provides remote monitoring and control. According to the relevant national technical specifications, the system should be set up security camera, TV monitor, video recorders (or DVR) and image processor, the user can at any time any tune to see a picture of any remote control camera etc..Closed circuit monitoring system generally consists of three parts: front-end equipment, transmission part, back-end equipment (including control equipment and display equipment).The main components of closed-circuit monitoring system are: camera or image acquisition device, image transmission and control equipment, image processing and display equipment. Closed-circuit television monitoring system of the technical requirements are: the clarity of the camera, the system's transmission bandwidth, the video signal to noise ratio, television signal format, cameras achieve higher quality and operation function, as well as the environment of each part of the system to the extent.

Q:Now the design institute design closed-circuit monitoring, how to still use analog monitoring ah?

The difference between analog monitoring and digital monitoringIn accordance with the principle of economic application and stability, designers of design institutes recommend the use of analog signal monitoring system. Simulation monitoring is to generate analog signals, through the acquisition card or hard disk recorder converts analog signals into digital signals stored, or by the more primitive way is through the video and other media to store it.

Q:What should be paid attention to in the installation of security monitoring?

The correct grounding can minimize the effects of the ground loop. The voltage difference between the different ground shall not exceed 100mVAC (measuring the pressure difference between the disconnected coaxial cable and the shield layer and the ground terminal of the BNC behind the device).

Q:Closed-circuit monitoring software

Click the WIN keyboard to see the taskbar, which is on the keyboard, the one between Ctrl and Alt, and the icon with the Microsoft Icon

Q:How to improve the transmission speed of closed-circuit monitoring in the network

Principle：1, minimize the size of the data packet being transmitted. This requires the video card to have a good compression.2, to improve the network transmission speed. The speed is related to both sides.

Q:Is it okay to use CCTV for surveillance cameras? Is video line the same as closed route?

It's not the same thingMonitor line model: SYV75-5, -3, usually blackCable lines: SYWV75-5, usually whiteThe same brand with the specifications of the monitoring line, more expensive than cable TV line

Q:What should be paid attention to when installing decoder in CCTV system?

Note that the distance from the monitor is too far away and requires SDI or HDIM light converters3 、 the installation environment conforms to the electrical specifications of the decoder
