Figure 3.4.4. PTZ Control setup screen.
To control the PTZ functions of the camera, connect the controller to the RS-485 port.
For speed dome cameras that supports RS-485, connect them directly to the RS-485 port. But if
the camera is controlled with RS-232C, it is needed to use Signal Converter (RS-485 to RS-
232C).
In the PTZ control setting in the setup menu, user can select or set the protocol type of the
camera which is the same as the one that is installed on the site. If the camera has a specific
camera ID, select the camera ID using Left/Right buttons.
