okshadow 0 Posted April 22, 2010 I bought a ULTRAK KC552BCN camera which is 24v, were you connect the power there are three tabs -G- do you have to have 24v on both sides of that and ground in the middle or how does it work, I have always used 12v cameras and not 100% sure where to go now.

Soundy 1 Posted April 22, 2010 The "ground" connection is there mainly to achieve UL certification. In most instances, you don't need to use it - just connect your 24VAC supply to the 24V tabs. Share this post Link to post Share on other sites
bpzle 0 Posted April 22, 2010 Right. AC cams are also not polarity sensative. Unlike DC cams, it doesn't matter which lead goes where. Share this post Link to post Share on other sites
