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.
