26 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 audio using the AUDIO IN port on the rear panel. You must first have a self-powered microphone or an audio camera with an RCA-type audio connection to use this port.

To utilize the listen-in feature, your camera must have a built-in speaker.
To utilize the two-way talk feature, your camera must have a built-in speaker and microphone.

The first 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).
