rory 0 Posted May 10, 2008 Is it a Distributed power supply, or a single plug in transformer? Maybe the cameras power board doesnt reset or something. Do you also have to reset the DVR or just the cameras? Share this post Link to post Share on other sites
si_kungs 0 Posted May 10, 2008 it is a distributed power supply. just turn off the power supply and it will be up an running again. it shows black screen after the brownout. don't need to turn off the dvr. so it is also possible that the camera board did not reset?
