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:
