Appendix A
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 12VDC GND D+ DDI DO
Cable Color Brown/White Blue/White Purple/White Gray Green/White Orange/White
Function DC 12V (50mA maximum) GND RS485 data + RS485 data Digital signal input Digital signal output
User can refer to the schematic below to make a proper connection between I/O connector and external sensor and output device. Explanation of External I/O Circuit Diagram:
