Securame 0 Posted March 9, 2016 You are right, if he has no audio in or only one audio in, it is time to change DVR. Share this post Link to post Share on other sites
SeattleBrian 0 Posted March 9, 2016 smcctv, I assume this is an IP system? Not analog? A) Connecting microphones to the NVR is an option. The input will be associated with a camera, so that audio & video for that camera channel are recorded together. My NVR has a single audio input, and it is associated with camera channel 1. Not configurable. B) Connecting a microphone to an audio-capable camera is an option. Or buying a camera with built in mic. In both cases, the audio is then recorded with the correct video. ie: The audio is encoded into the IP data stream from camera to NVR. Considerations: External mics usually require a power source. My POE camera with mic needed a cable for 12V, sorta defeating the benefit of POE. Mic location, sensitivity, background noise, etc. Share this post Link to post Share on other sites
