Security monitoring, the monitor is too far away from the hard disk video recorder, how to answer?
First of all, if you want to connect to the security room through the VGA line, this is not advisable. Because the VGA line needs to be made to order, and the quality of the VGA line is uneven, the quality is good to 10 yuan per meter, it is estimated that no one will order 100 meters, so many, at most 20, 30 meters only.
Or, as you say, connect the video recorder of the computer room to the Internet, and put it in the security room, a computer, LAN can. This can also be achieved, disadvantage is high cost, but also as the video network transmission in the past.
You can only put a monitor, which is connected with a video line, general DVR with AV output, 100 meters video line to the security room, then the TV can be connected to the display, then you need to connect the AV-VGA adapter. This is the cheapest way to save money.
