LNR Series: Connecting and configuring audio capable cameras

Your LNR Series NVR system supports audio recording with audio-capable cameras (not included). Audio-capable cameras have either a built-in microphone or a camera with audio input cables that can be connected to an external microphone. Depending on your camera model you can either use Listen-In audio to be alerted to sounds occurring around your camera or you can also use 2-Way Audio to speak and listen to those around your camera with an external speaker (not included).

Prerequisites:

  • Ensure that your camera is audio-capable. Check your camera user manual for details. Click here for downloads and documentation for your product.
  • Ensure that you have connected your cameras to your Router and the same Local Area Network (LAN) as your NVR. Click here for information on how to connect your IP Camera to your NVR.

LIMITATION: The MIC IN / OUT ports on the rear panel of the system cannot be used for audio recording. They are used for service only.

IMPORTANT: Using surveillance audio can be restricted or regulated depending on your location. Always verify with local authorities how to properly make use of your audio enabled system without breaking any privacy laws. Audio recording without consent is illegal in certain jurisdictions. Lorex by FLIR assumes no liability for use of its products that does not conform with local laws.
