Cable Connection
Connecting to PTZ Cameras through an RS-485 Port in PTZ Control Mode
The wiring for other cameras are similar, the following takes box camera as an example.
When using an RJ-45 connector, you can connect the RJ-45 connector to the PTZ control cable as
follows:
Connect T+ of the RJ-45 connector to A (RS485+) of the PTZ control cable; and connect T- of the
RJ-45 connector to B (RS485-) of the PTZ control cable, as shown in Figure 3-4.
If the PTZ camera uses a ground wire, connect the ground pin of the PTZ control cable to the
ground pin (pin 7 or 8) of the RJ-45 connector.
