1. A security camera system comprising: an imaging system for capturing frames of a scene; an infrared illumination system for illuminating the scene; a controller for analyzing images of the frames for objects in the scene exhibiting image aberrations in the captured frames of the scene and controlling a power provided to the infrared illumination system, which illuminates the scene, based on the analysis of objects in the images; wherein the controller increases the power provided to the infrared illumination system, waits for a settling time for the infrared illumination system to reach steady-state illumination, and then determines whether or not the increased power increased image aberrations in the images of the frames.
