rocmay 0 Posted June 22, 2011 Ok I'm taking over a adt system has anybody ever messed with the pin out on these. The cameras are being fed into a adt dvr with a rj11 plug. I would like to keep some of the cameras going but change out the dvr system. I know it is a 12 volts on the red and black but im not sure how they are getting video back out of the system. I would like to cut the plug at the dvr, feed power to the camera's via another power supply but change over to a bnc via a ballum. I tried to use the yellow and black but I can't seem to get the video out of it for some reason. Share this post Link to post Share on other sites
jxk716 0 Posted June 23, 2011 I had an ADT system years ago and found the manual for the monitor which housed the power source. From what I can remember they were. 27 or 28 VAC but I can't be sure. The book also has the pinout. I promised myself never to throw that away so I will look for it and post details asap. Share this post Link to post Share on other sites

thewireguys 3 Posted June 23, 2011 easiest way to up grade is keep the ADT dvr and use the look outputs to your new DVR Share this post Link to post Share on other sites
