Appendix A: Alarm I/O Connector
Some features of the Camera can be activated by the external sensor that senses physical
changes in the area Camera is monitoring. These changes can include intrusion detection or
certain physical change in the monitored area. For examples, the external sensor can be a door
switch or an infrared motion detector. These devices are customer provided, and are available
from dealers who carry surveillance and security products. Electrically, they must be able to
provide a momentary contact closure.
This Camera provides wires for general I/O terminal and RS485 interface as below:
Cable for I/O connectors:
Name Cable Color Function
12VDC Brown/White DC 12V (50mA maximum)
GND Blue/White GND
D+ Purple/White RS485 TX +
D- Gray RS485 TX -
DI Green/White Digital signal input
DO Orange/White Digital signal output (alarm)
User can refer to the schematic below to make a proper connection between I/O connector and
external sensor and output device.

 THE LOW VOLTAGE/CURRENT CIRCUITS AND HIGH VOLTAGE/ CURRENT CIRCUITS
ARE IN THE NETWORK CAMERA CIRCUIT. THE QUALIFIED ELECTRICIAN SHOULD DO
THE WIRING NOT BY YOU. INCORRECT WIRING COULD DAMAGE NWTWORK
