Serial control allows remote PTZ, preset calling/setting and other control from 3rd party devices (e.g. joystick, Crestron) or software (e.g. RocoSoft) over a wired connection to the camera. 

Most meeting room users will be perfectly content with their infrared hand-held remote control, especially when all PTZ command are executed via preset calls. Some operators will require a better control interface for their application:

  • Produced events with camera operator(s), rooms with centralized touch-panel control systems, like Crestron/AMX/Extron, where all hand-held remotes have been removed from the room, etc...). 

Cameras with serial control capability will often conform to the industry standard mini-Din8 connector and Sony VISCA protocol. This makes using this feature fairly straightforward, as long as you have the right control cabling and set both the camera and controller to a matching baud rate, port number, and Visca control protocol.
