Appendix A: Alarm I/O Connector
Some features of the Network Camera can be activated by the external sensor that senses
physical changes in the area Network 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, 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 Network Camera provides a general I/O terminal block as below:
Pin Function
1 12VDC power supply (50mA maximum)
2 Digital Input
3 GND
4 Alarm Output
User can refer to the schematic below to make a proper connection between I/O connector
and external sensor and output device.
