securitynow.us 0 Posted February 22, 2013 (edited) I do not know where you are located, but be sure you check with your local laws first to see if audio surveillance is allowed where you are. Some states/areas consider it to be eavesdropping or wiretapping. Edited February 22, 2013 by Guest Share this post Link to post Share on other sites
securitynow.us 0 Posted February 22, 2013 If it is allowed where you are located, if the DVR/NVR that is present allows for audio, you just need to run a cable for audio with a small microphone, and then plug it into the audio input. I've done this for a customer where we just poked a small hole in corner ceiling tile and slipped the small mic in, wasn't noticeable. Share this post Link to post Share on other sites
bluegene 0 Posted February 22, 2013 Yes, I am covered as far as the state law is concerned.OK so is it possible to grab a microphone and hook it straight into the dvr audio-in because i don't want to spend money on a new analog camera that has built in audio feature..Thanks Share this post Link to post Share on other sites

RecycledEl 0 Posted March 5, 2013 I just ordered a few mics off eBay. Search for "security mic." They plug into the same power connection a CCTV camera does, and plug into an RCA cable. I have to admit: I was confused for days. I kept looking for an adapter from mics I already owned to my security DVR. I finally realized they need a different kind of mic. (I'm not saying an adapter is not available, I'm saying dedicated mics make more sense in my case.) Share this post Link to post Share on other sites
