What are the security monitoring TV walls required?
This is easy to do, ah, I made a school two days ago, the project is doing so, and to the back end, with hard disk video recorder, the first hole in the upper left corner, pull a video line to the LCD TV, you can achieve. After you can make your hard disk video recorder online, register a peanut shell, so that 9 people can see it
The front end uses the network camera, then the surveillance video frequency acquisition has not been a problem.The 21 points are in different places, and the front end and the back end are all connected by network devices, of course. Don't you have a wiring problem?. Is the distance between the 21 points very far?Each video signal needs to be on the wall, it is best not to use the TV, with professional LCD monitor will be better. In addition to security monitors, you also need screen splitter, TV wall rack, and video recorder if you want a hard drive.
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
