Appendix E: Alarm I/O Connector

Interfacing to the External I/O
Some features of the Camera can be activated by an external sensor that senses physical
changes in the area device 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 device provides a general I/O terminal block with one digital input and one output for
device control. Pin 2 and 3 can be connected to an external sensor. The input voltage will be
monitored from the initial state 'LOW'. If the external sensor need 12VDC power, then it can
connect to Pin1 (50mA maximum). The Alarm Output of pin 3 and 4 can be used to turn on or
off the external device.
