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.
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.
