A: Wire selection
1, video cable
The camera to the monitoring host is ≤200 meters apart, and the RG59 (128 series) video cable is used.
The camera to the monitoring host is separated by >200 meters, using the SYV75-5 video cable.
2. PTZ control line
The gimbal is separated from the controller by ≤100 m, and the RVV 6×0.5 sheathed wire is used.
The gimbal is separated from the controller by >100 m, and the RVV 6×0.75 sheathed wire is used.
3, lens control line
RVV4×0.5 sheathed wire is used.
4, decoder communication line
