Q:What are the security monitoring TV walls required?

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.

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

Computer monitors can be used for closed-circuit televisionNow there is a way of looking at HDTV, that's what it is. Play high-definition video files on your computer and broadcast the signals on tv. In other words, it is to use television as a big monitor, and to use the sound of the TV as the output speaker.

Q:How to install home security monitoring system?

If the house is under construction, decoration, the use of wired home security system is a good choice. The outdoor monitoring system monitors the house and property facilities from invasion. If you want to install surveillance systems outdoors, it's better to use night vision cameras so that you can see images in very low visibility nights. And these surveillance cameras are also equipped with moving sensors. When can the audible alarm to detect any ring. One drawback is that these mobile probes can also be triggered by some animals (such as mice, dogs, etc.) and cause false positives. The good news is that the new detectors have been able to judge the weight and size of moving targets before they are triggered, which greatly reduces the likelihood of false positives.

Q:What do you need to add an ordinary home computer to a closed-circuit monitoring host?

Look at the camera monitoring system there are several points, according to the situation to buy a video acquisition card, buy soft card, low price, good quality video if you want to the best use of the card, the 7130 chip currently on the market price is low, but the image quality is not high.
