Abstract
Hidden camera detection systems and methods are disclosed herein. An example method includes illuminating a surface with infrared light, obtaining an image of the surface using an infrared camera, and determining the presence of a hidden camera associated with the surface by determining a difference in spectral reflectance between how the infrared light is reflected off of the hidden camera as compared to how the infrared light is reflected off of the surface.
