Appendix A: Alarm I/O Connector
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. The pin5 and 6 are connected to RS485
interface.
