Bridgett15 0 Posted July 22, 2011 I have a Zmada 4 camera system that I purchased online. When I received it, it did not have a dvr. I have since purchased it and installed. I am now trying to playback after recording and I am getting an error message not HDD. Any suggestions? Pretty much surveillanc system illiterate..lol.
