WebFeb 14, 2012 · In our field testing, the optimal range of IR light or producing clear evenly exposed surveillance video is about 1-5. When measuring IR, the metric used is microwatts/centimeter squared or uW/cm2. As such, this is 2-5 uW/cm2. If you have substantially more than 5 uW/cm2, the result will likely be an overexposed image.
