Bests & Worsts Reviews from Amazon

Well constructed 850 nm (wavelength) IR "floodlight." Installation Note/Consideration: The AC/DC adapter is not the typical "wall wart" type (at the plug end of the power cord) - this one has a 2-prong 120vAC to 12vDC 3amp in-line rectangular adapter (dimensions 1.25"x1.5"x4.25") - what you'd typically have with a laptop computer. It also comes with a power connector that can be wired directly to a 12vDC source in lieu of the 120vAC adapter. A) Any reviewers reporting this product as one-star/or stating it "doesn't work" with their camera - likely have cameras of incompatible design (e.g. 940nm IR camera with an 850 NM IR illuminator, or vice versa.). *--> Before purchasing, you need to check your IR capable camera's specifications and closely "match" the Illuminator wavelength with your camera(s) wavelength. The images sensors in cameras are designed for specific frequencies ranges and are more/less sensitive to frequencies outside a design range. If you use an illuminator outside of or on the edge of your design spec, your illuminator will be less effective with your camera, and thus you'll need either more iluminator power, or a more compatible r frequency, so it's best they be closely matched. B) Regarding reviewer comments about this illuminator being visible to the "bad guys" please note: 1) 850nm illuminators in the dark, will emit a clearly visible glow to the naked eye - appearing as a dim red glow (in the dark). 2) 950nm illuminators in the dark, using so called "covert/stealth LEDs" are much less visible to the naked eye - typically appearing as a very very dim purple glow - so they are much harder to see. Note: Any illuminator regardless of frequency is visible to "night-vision" devices passive or otherwise (vs. the naked eye). The good and bad of increased range and width of illumination: If you have flying insects present at night, you may have to decrease your motion detection sensitivity a bit because you will have a lot more "visual contacts"/triggers with the significantly increased range and width of illumination this illuminator gives your security camera.
