Is it OK to monitor TV instead of closed circuit?
It is normal to use the cable in the project, but you need to install a dual effect line conveyor. If there is no UTP conveyor, your signal is not shielded, so there is interference and resistance. In this case, if you do not install a twisted pair conveyor, you have to change the video line. It does not rule out that the site you installed has interference (the probe of the network cable), and you also need to install an anti-interference device.
Surveillance TV can be used instead of closed lines.
Monitoring system is one of the most widely used systems in security system. Now, the site monitoring system is a handheld video communication device, and video surveillance is the mainstream now
