Slim design. Built in IR LEDs. Unfortunately, my NVR can only dewarp 1 camera at a time and I bought 2. I replaced these fisheye cameras with cameras that have 2 cameras in 1 housing. This was much better for my use. The fisheye cameras work beautifully. I just wished I bought the type that have built in dewarping or that my NVR could dewarp more than 1 camera at a time.
Great way to see everything the fisheye takes some use to if mounted on the ceiling, but put on. The corner of a building and see two sides of a house at ones saves on camera placement. Good zoom and clear picture .
