Answer 1

In short, you must use three wires with a cross section of at least 0.5 mm2.
RS-485 A, Rs-485 B and 0. Using them, you need to combine the push terminals on the registrar with those on the Scanners.
If it is long, then it is desirable to know the brands of scanners, a photo of the rear panel of the recorder and a photo of the PTZ menu of the recorder.
