D Series DVRs: Audio recording

The system supports Lorex HD audio cameras, which transmit audio through the same coax cable used for video connection.

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.

NOTE: Use of an external microphone allows you to record audio on Channel 1 of the system. It cannot be moved to a different channel.

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).
