N910 Series - 4K+ Ultra HD 12MP 16 Camera Capable NVR: Connecting Audio
The following article provides instructions for connecting audio devices and enabling audio recording on your NVR.
Make sure that 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.
Important: Use of an external microphone allows you to record audio on one channel on the system as long as the connected camera has a built-in speaker.
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).
