Adding External Mic Units to your IP Cameras

Some some cameras come with an internal microphone to capture audio:

In some environments the internal mic may not have enough coverage for customer needs. In this case you can use an external mic to help to increase coverage, or install in a better location.

 

What to know:

  1. Only one Cat 5/6 cable run is required
  2. External Mic connects into pigtail (Audio In) of supported Cameras
  3. You will need to add external AC to power the Microphone
  4. Camera Settings – Set to use External Mic and Adjust mic level inputs

Supported Cameras:

NCE-DFA, NCE-DTA, NCS-FEA, NCs-NMP-4, NCS-NMP-3, NCS-4CM, NCE-DVX-6, NCE-DVM, NCE-BVM, NCS-PMD-3, NCS-4LD-8, NCE-DVA-2, NCE-BVA-2, NCE-DVF-2
