    Default Infrared (IR) Illumination vs. Infrared Imaging

    Many traffic cameras, particularly those for automatic license plate recognition (ALPR), say they incorporate "infrared illumination". For these cameras, is the imaging all IR or is it both IR and visual spectrum? The new IR plate covers seem a bit more stealthy than the angle-sensitive covers, so I'm trying to figure out if the new type would be at least as effective as the old, and/or for which types of cameras.
