Operating Instructions

4.2Interfacing to the External I/O

The Alarm mode in the Image Transfer feature requires the external sensors/ devices to be connected to the External Sensor Input of the External I/O. Certain features of this Network Camera can be activated by an external sensor that senses physical changes in the area Network Camera is monitoring. These changes can include motion detection or a physical change in the monitored area. The external sensor can also 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.

	Explanation of External I/O
Pin	Function
1	GND
2	DC Power Output Terminal
	• 12—16 V DC
	• Maximum of 100 mA load drive is possible.
3	External Sensor Input
	• External Sensor Input receives the signal produced by the alarm
	sensors, (e.g., door sensor, infrared ray sensor). Those signals can
	activate Image Transfer in the Alarm mode feature on page 68.
	• Use it by opening or GND short-circuit.
4	External Device Control Output
	• External Device Control Output sends the electric current to activate
	the external devices, (e.g., light, buzzer).
	• External Output Control window can set the External Device Control
	Output. Refer to page 83.
	• It is an open collector circuit, and the maximum drawing-in current is
	100 mA. Prevent the maximum voltage from exceeding DC Power
	Output voltage of pin 2.
