Alarm Outputs

The camera incorporates two (2) types of alarm outputs: one dry contact relay and three (3) open collector outputs or transistor outputs.

Configuring a Dry Contact Relay

The dry contact relay acts like an on/off switch. It has a maximum voltage rating of 2 A @ 30 DC.

1.Connect the appropriate stripped wire to the camera’s COM connector.

2.Connect the appropriate stripped wire to the N.O. or N.C. connector, depending on your requirement.

Configuring an Open Collector Output

Outputs 1, 2, and 3 are open collector types. These outputs must be connected to a positive voltage between 5 and 32 V to complete the circuit, with a maximum voltage rating of 32 VDC @ 150 ma.

1. Connect the appropriate stripped wire to the open connector (1, 2, or 3) of the transistor.

2. Connect the appropriate stripped wire to the ground (GND) connector.

11.6	Audio Connections (Optional)
	The camera is capable of receiving line level input signals and transmitting them over a
	network. It is also capable of receiving audio from the same network and sending it as audio
	output from the camera. The audio input signal is transmitted in sync with the video signals.
	As a result, for example, a door intercom system can be connected at the camera location.
	Notice!
	The line ports of the intercom should be used for transmitting audio signals on the intercom
	systems.
	The audio line input is not suitable for direct microphone signal connection.
	The audio line output is not suitable for direct speaker connection unless using a powered/
	amplified speaker with line level input.
	Audio Line Input Specifications
	The following Line Input specifications should be complied with in all cases.
	Max. Input Voltage	1 Vrms
	Impedance	9 K Ω (typical)
	Shield	Bare copper braid: 95% coverage
	Internal gain level adjustment is available in case the signal level is too low.

Audio Line Output Specifications

The following Line Output specifications should be complied with in all cases.

Typical Output	1 Vrms
Voltage
Impedance	1.5 K Ω (typical)
Shield	Bare copper braid: 95% coverage

Internal gain level adjustment is available in case the signal level is too low.
