Today, Dicheng cable editor will talk about the selection standard of monitoring cable RVV. In the above video surveillance cables, we see that the use of RVV cables is very much. RVV full name: PVC insulated PVC sheathed flexible cable. The letter R stands for flexible cord. Of course, when R is placed behind V, VR means PVC soft sheath. Is the implementation of GB/T. In the application of RVV cable in monitoring, we can understand the relevant standards one by one, and we can see whether it meets the requirements in the actual installation. 1, monitoring video line camera to monitoring host distance ≤ 100 meters, with 75-3/64

1. The distance from the monitoring video line camera to the monitoring host is ≤ 100 meters, and 75-3/64P video line is used. The distance from the camera to the monitoring host is ≤ 200 meters, using 75-3/96P video line. The distance from the camera to the monitoring host is ≤ 300 meters, using 75-5/96P video line. The distance from the camera to the monitoring host is ≤ 500 meters, using 75-5/128P video line. The distance from the camera to the monitoring host is ≤ 800 meters, and the video line is monitored with 75-5-1/128P.
2. The distance between the pan-tilt control line and the controller is less than or equal to 100 meters, and the RVV6 × 0.5 sheath line is used. The distance between the pan-tilt and the controller is> 100 meters, and RVV6 × 0.75 sheath line is used.
3. The lens control line adopts RVV4 × 0.5 sheath line.
4, decoder communication line camera to monitoring host distance ≤ 200 meters, should use RVVP2 × 0.5 shielding line camera to monitoring host distance ≤ 500 meters, should use RVVP2 × 0.75 shielding line
5. The power line of the camera can only be reasonably selected through calculation. The specific calculation method is not introduced here. The following is a list of how thick the line diameter is to be selected for the projects I often do, hoping to be helpful to everyone's projects:
