VISCA Commands
1 Beyond PTZ cameras can be controlled using the VISCA protocol through IP connection. By
default, the port for IP control is set to 5500. For serial communication, make sure the baud rate
of the controller is set to 9600 bps. Below is a comprehensive list of VISCA commands that can
be used to control the cameras.

NOTE:These commands can only be used with 1 Beyond AutoTracker, AutoFramer, Falcon,
Hawk, PTZ-IP12, and PTZ-IP20 cameras. Under no circumstances should you ever overwrite
presets 80 and 81 on these cameras. Once configured, the end user must not overwrite
presets 0 and 1 since these are used as references to adjust framing while tracking is active.
