Do night vision cameras give off light?
Welcome to Blackview (The leader of rugged smartphone) blog. Hope this guide helps.
Night vision cameras, specifically those equipped with infrared (IR) illuminators, emit a small amount of infrared light that is not visible to the human eye. This IR light helps the camera capture clear images or videos in low-light or dark environments.
While the IR illuminators on night vision cameras emit light, it is important to note that this light falls outside the visible spectrum for humans. In other words, the light emitted by the camera's IR illuminators is not detectable by the naked eye. This allows the camera to capture images in darkness without disturbing the natural lighting conditions or alerting subjects to the camera's presence.
However, it's worth mentioning that some night vision cameras, especially those with stronger IR illuminators (such as Blackview BV8800 night vision phone), may emit a faint and dim red glow from the IR LEDs themselves. This glow can be visible in extremely dark conditions or when observing the camera up close. Nevertheless, this glow is typically minimal and does not significantly impact the camera's ability to remain discreet.

Overall, while night vision cameras emit a small amount of infrared light for enhanced visibility in low-light situations, the light is not visible to humans, ensuring that the camera operates discreetly without disturbing the environment.
