A night vision camera does not emit radiation; instead, it amplifies existing light, typically in the infrared spectrum, to create a visible image in low-light conditions. Some night vision devices use near-infrared (NIR) illuminators, which emit infrared light that is invisible to the naked eye but can be detected by the camera. This allows for enhanced visibility in complete darkness. Overall, night vision cameras primarily rely on the detection and amplification of ambient light rather than emitting their own radiation.
