6.3 RS-485 

 

 

The camera adapts RS-485 in half-duplex pattern, which 

is a two-pin connectivity, as shown on the right picture.   

 

Installer must pay attention to the polarity of these two 

pins – yellow wire is the POSITIVE end, and orange is the 

NEGATIVE. Communication between controller and 

camera will break and control will not function if they are 

reversely connected. 

 

The RS-485 communication may run for 4,000 feet if the system network is properly 

built. Two important factors should be handled with care during the system 

build-up--- baud rate and termination impedance. More information about RS-485 

are in sections “Protocol and Baud rate” and “Applications”. 

 

6.4  Alarm Input and Alarm Output 

This camera is equipped with 3 alarm inputs and one alarm output for intrusion 
management. Installers may connect the inputs to the various sensors and program 
the camera to move and monitor specific spots for monitoring when evens take 
place. Dwell time for monitoring is programmable, subject to the system. Refer to 
the diagram on right for function assignments of the alarm I/O.

This speed dome has three alarm inputs, and each input is given by the software a 
companion view preset. When trigger single is sent to alarm-in, the following 
reactions will be taken by the speed dome:

The pan-tilt mechanism will move lens to the preset.
