18  Connecting Audio Devices

The system supports Lorex HD audio cameras, which transmit audio through the same network cable used for video connection and powering the camera. The system can also record one audio channel using the AUDIO IN port on the rear panel. You must have a self-powered microphone or an audio camera with an RCA–type audio connection to use this port.
The second RCA-type connector on the back panel is the AUDIO OUT port, which can be used to connect a self-powered speaker that will play audio from the system (requires audio-capable camera or self-power microphone).
