VISCA Commands
1Beyond PTZ cameras can be controlled using the VISCA protocol through either a serial (RS-232 /
RS-485) or 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.
Start/Stop Tracking
To start or stop tracking on the 1 Beyond Hawk camera, call the following commands:
Command Command Packet Comments
Start tracking (Recall CAM_Memory 80) 8x 01 04 3F 02 50 FF Call Preset 80, camera addr x
Stop tracking (Recall CAM_Memory 81) 8x 01 04 3F 02 51 FF Call Preset 81, camera addr x
NOTE: These commands can only be used with AutoTracker, AutoFramer, Falcon, and Hawk
cameras. Under no circumstances should presets 80 and 81 be overwritten on these cameras. Once
configured, presets 0 and 1 must not be overwritten since these are used as references to adjust
framing while tracking is active.
Privacy
The PTZcameras can be tilted backwards for privacy when the camera is not in use. To tilt the PTZ
cameras backwards, call the following commands:
NOTE:Speaker tracking must be disabled to tilt the PTZ cameras backwards.
