Appendix A: Alarm I/O Connector
Some features of the Video Server 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:
