Method and system for capturing and storing significant surveillance images using a plurality of i/r wavelengths
A method and system may include a first light source for generating infrared light at a first wavelength. The system and method may include a second light source for generating infrared light at a second wavelength that is different from the first wavelength. The system and method may also include a camera module for activating the first infrared light source to capture a first image of an object with the first infrared light source.
