jj3777 0 Posted December 30, 2005 if i get one of the wired mics from the web site. how do I install the mic? does it connect with the camera wire that connects the camera to the dvr. Share this post Link to post Share on other sites
rory 0 Posted December 30, 2005 A Louroe Mic? Depends on the mic as to what wire goes where for the mic, normally power and audio, 3 wires, can use standard 2 pair telco, 3 wires used are power, ground, and audio, then you bring that wire back to the DVR location and splice off for power and audio, and audio goes to the DVR, Power goes to a 12VDC source. Anyway, once its a mic like those, just tie it into a RCA cable, splice it how ever you wish, you can even use a Terminal Strip to join it if you dont like tape or heat shrink. Ground to ground, center to center, the RCA plug end goes into the Audio Input on the DVR. Share this post Link to post Share on other sites
spytown 0 Posted December 31, 2005 you could even get a cheap mic like this one from COP http://www2.cop-usa.com/ebproductdetail.asp?id=350 Share this post Link to post Share on other sites
Gesualdo 0 Posted January 21, 2006 How about for outdoor? Either at the camera(dome) or seperate. Share this post Link to post Share on other sites
rory 0 Posted January 21, 2006 outside, you will get "alot" of background noise so it isnt suggested, but you could use a weatherproof box and caulk a mic into that somehow .. Share this post Link to post Share on other sites
Gesualdo 0 Posted January 22, 2006 I figured that but was wondering if there was something other than the plates for next to doors that was weather proof and less obtrusive and obvious. By the way nice picture. Is that the latest in beach wear? Share this post Link to post Share on other sites
