Kawboy12R 0 Posted October 31, 2013 12v DC is a bit cheaper usually and is best on short runs. 24v AC is much better at avoiding voltage drop on long runs. Share this post Link to post Share on other sites
uaichina 0 Posted November 12, 2013 If the camera can support both DC12V and AC24V, there must one bridge chip inside which can transform 24V to be DC12V. If the distance from PSU to camera is closed, you'd better use DC12V that can make the camera working more reliable. If the distance from PSU to camera more than 2 meters, you should select AC24V for the transmission distance of AC24V is much longer than DC12V.
