Appendix A: Alarm I/O Connector
Some features of the IP camera can be activated by the external sensor that senses physical
changes in the area IP 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 device provides a general I/O terminal block with one digital input and one output for device
control. The pin 1 is located at the right side of terminal block from rear view. 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.
This IP camera provides a general I/O terminal block as below:
Line Color Function
Brown/White 12VDC power supply (50mA maximum)
Blue/White GND
Green/White Digital signal input
Orange/White Digital signal input
User can refer to the schematic below to make a proper connection between I/O connector and
external sensor and output device.
