jobes 0 Posted May 13, 2014 I have GeoVision GV-BL1210 cameras that supposedly have mics built-in but I cant seem to get this working right. I'm running CAT5 (POE) and but the camera also has RCA jacks which I'm not using. With speaker/mic built-in shouldn't audio be carried over the ethernet back to the NVR? GeoVision is really confusing me saying this camera needs a mic to work the specs say two way audio. Anyone have a clue? Share this post Link to post Share on other sites
jeromephone 6 Posted May 13, 2014 Yes you do need a microphone and if you want a speaker you need to add that also. Look at the ETS website as they make a microphone that is setup to use the poe to the camera to power it. Share this post Link to post Share on other sites
