Superb image quality - rivals almost a night vision device. I use the camera for covert surveillance. One downside is that it gets a little warm, maybe it's the additional *7456 OSD chip. If this is an issue, maybe I'll mod my camera. Here are images captured using a telephoto lens at night with only dim street lights. The OSD was misplaced at the center during testing. You can place it anywhere on the screen and add any text of your choice. The first 3 images were captured with a cheap 640x480 USB video class capture device that internally uses MJPEG compression, saved as BMP and recompressed again as JPG, so there is a quality loss. For comparison, I also captured video using a D1 DVR that captures at full D1 resolution (704x576) applies H264 compression, and the screenshot was saved directly to PNG format - it is the last 2 images where a timestamp is visible. The D1 DVR comes close in quality to an old DV format VCR. As far as analog SD (PAL/NTSC) cameras go, this is a top quality camera.. Bonus: The camera has a similar effect to old image-orthicon tube cameras - check out the halo that surrounds transitions of dark-light objects The next best thing would be an AHD/TVI/HDMI camera with this night-vision technology!
