Review on Gawker G1083PDIR Dome Security Camera, 1080P HD-TVI/AHD/CVI and CVBS(Default) Video Out Switchable, True Day & Night, IP66 Vandal Proof, 2.8-12mm Lens, IR Smart, DC12V/AC24V CCTV by Donna Armstrong

Thought we'd save a few cents and buy them from Revain. After spending over eight hours trying to get it working, we concluded that something was wrong. We bought four of these devices. One is noisy, one is too rich in contrast (classic horizontal saturation bars), the rest stays within limits. It advertises an external button to access the standard OSD menu to allow these various video settings to be adjusted. -- No external button as advertised. And there's no miniature internal mouse switch like you'd expect from professional security cameras. There is nothing in the instructions either. I called the seller, they don't know either. -- So I had to stick with a professional CCTV shop. I actually have >$1000 in work to save a few cents and a few hundred on useless hardware.
