How does an Outside Night Vision Security Camera Work?
A Night Vision Security Camera uses something called image enhancement or image intensification. The camera contains a lens that senses light but not in absolute darkness, where you would need thermal imaging. This requirement isn’t normal in the home or factory situation where there is usually some light from the street or the building. The camera then converts and magnifies the light photons through a photocathode which produces a very good image on the camera’s screen. Night Vision Security Camera infrared illumination and LED’s and Images When you read descriptions of a night vision security camera and it uses words like infrared illumination and infrared LED’s [Light Emitting Diode], what this means that the area is saturated with reflective infrared light, so the night vision security camera gets far greater detail. It’s similar to shining a spotlight on an object making it far easier to see, and as a result you get far better and clearer image in the dark. This means not blurry
