I use this camera with a 4 camera DVR set-up in a 0 lux environment. Typically I need at least 10 meters of lit area to work with, this camera provides it with no problem. I have used one of these cameras to cover a 30 meter area with great results. The beam pattern is even and covers the entire viewing area, cheaper units have the typical round pattern that doesn't cover the edges. You couldn't do better for the price, plus the additional lens is great!
