RS-485
RS-485 is a serial data communication protocol that allows multiple PTZ
cameras on the same twisted pair cable to connect via serial connection for
control from one camera to the next
RS-485 offers high data transmission speeds (Up to 35Mbps on 10 meters
distance and up to 100Kbps on 1200 meters distance) and is able to cover
relatively long distances (approximately 1200 meters)
When included with an IP camera, the RS-485 interface can be used for
connecting the IP Camera to an external PTZ scanner
