Connecting multiple PTZ Cameras is a simple process that takes several PTZ cameras and allows them to use one joystick. The easiest way to connect multiple PTZ security cameras is to Daisy Chain the data line.
PTZ cameras have three cable connectors, data (to run the joystick), power, and video (which are usually residing in one cable). Data can be daisy-chained but power and video cannot.
