I used VISCA commands to TCP port 5500 for the IV-CAM-I20s we just installed. Most of the commands are the same as any other PTZ dating back to Sony EVIs and probably before. Never did find the Crestron module.
I was testing a system today with four Crestron 1 Beyond IV-CAM-I12-B cameras, and CP4n using the 1Beyond AutoTracker_IV-CAMA3 module. It appears to control the cameras but I did notice an error log entry in the processor about an exception at Line 522 in the SIMPL+ module. Sorry I didn't have time to research it further. . .
