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.
