Do IR night vision cameras give off radiation?
Welcome to Blackview blog. Hope the guide helps.
Night vision cameras typically do not give off radiation that would be harmful or noticeable to humans. However, it's important to clarify what is meant by "radiation" in this context. Night vision cameras can be categorized into two main types: those that use infrared (IR) illumination and those that rely on thermal imaging.
Infrared (IR) Cameras: These cameras use infrared light, which is a form of electromagnetic radiation, to illuminate dark scenes. The camera captures the reflected IR light to produce an image. The infrared light used by these cameras is generally at wavelengths of 850 nm or 940 nm, which are invisible to the human eye. While this is technically radiation, it is non-ionizing and not harmful to humans or animals. The amount of IR light emitted is also minimal, similar to the kind of light your TV remote control uses.
Thermal Imaging Cameras do not emit too.
In summary, while night vision cameras may involve infrared radiation, the type of radiation involved is non-ionizing and harmless. These devices either emit minimal IR light (in the case of IR cameras) or do not emit any radiation at all (in the case of thermal cameras). Therefore, night vision cameras are safe and do not give off harmful radiation.
