Network cable as a monitor video cable to monitor can, how to connect

1, the network cable is 8-core, with one of the core can do video

With the other 2 cores can be done with the power cord

And ordinary with the power cord and video cable to do the same. If you put the power cable alone, that one cable can connect 4 monitoring probes for video. Wiring is much easier than normal video cable. But if the distance is a little longer you need to add a twisted pair amplifier.

2, orange, blue, green and brown, in accordance with the twisted pair of wire winding degree of the larger connected to the farthest, the smaller connected to the closer the two twisted together to a camera, with the twisted-pair principle of anti-interference. Received 100 meters is no problem, far from the test. Active twisted-pair transmitter transmission, less likely to be interfered with.

3, outdoor wiring, as much as possible to choose the outdoor water-blocking wire, although the price is higher, but reliability can be guaranteed, for the interference of particularly strong places, such as power plants, substations, etc., it is recommended that the use of shielded wire, or in the ordinary wire coat metal pipe, such as the use of shielded wire must pay attention to the transmission distance, generally controlled in the 700 meters, the use of single-ended in the monitoring room, the principle of grounding; for elevators, the interference, it is recommended to use special twisted-pair elevator transmitter transmission. The interference of the elevator, it is recommended to use the elevator special twisted-pair cable.

4, the connection of the network cable, should be reliable welding, in the outdoors must do a good job of waterproofing, after treatment, pay attention to prevent immersion in water, you can put the joints in mineral water bottles, bottle mouth down, and then seal the mouth of the bottle; due to the use of twisted-pair cable transmission, "virtual ground" technology, coaxial cables are more prone to inductance of static or lightning, the choice of twisted-pair cable transmission, the use of twisted-pair cable transmission. Lightning, the choice of twisted-pair transmission equipment, be sure to pay attention to the selection of products with anti-static, lightning, if in the area of multiple mines, it is best to do in the front of the lightning grounding.
