Chapter 8. Alarm I/O
Connector
Some features of the Camera ca n be activated by an external senso r that sense s 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 securi ty 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 ext ernal
device. The pin5 and 6 are connected to RS485 interface.
