2.3 Setting Dome Camera Termination
The device which is connected at end of line, whether it be a dome camera or keyboard
controller, must have the cable for communication terminated by setting the appropriate DIP
switch. Without proper termination, there is potential for control signal errors. Total length of the
cable for communication should not exceed 4000ft (1.2km).
