dalis 0 Posted September 14, 2019 Hi all, this has been bugging for so long. I have a Q-See QC9116 DVR with cameras and wanted to add more cameras. This system is a HD Analog with BNC connectors. I ordered some cameras from china which they say are AHD but I don't get any picture. Talked to their tech support and tried moving some wires like they said. They said it's a analog and AHD camera. But they still couldn't get it going on my system. I had a friend with a cctv tool to check and the camera does work on AHD settings. But what is my problem? China uses a different AHD system or is there a difference between AHD and HD Analog? Should I try to purchase them somewhere else? Share this post Link to post Share on other sites
