CCTV Camera
I have noticed many CCTV cameras have a ring of LEDs around the lens - but
behind a front glass (Saw this on a drone which made me wonder....) Can the LEDs be of any use given the sort of useful distance that the camera is expected to focus on? Does having the LEDs behind the front glass cause scatter off dust and moisture to ruin the image. Are they just a gimmick? (a bit like using a flash on a camera at a stadium concert - see Inverse Square Law of Light) |
