cctv infrared camera
Are the CCTV cameras we see in the street in London sesitive infrared?
Would it be possible for an object in a dark London CCTV cameras view by using high powered infrared LEDs? The answer will not be used for illegal purposes!
Good question! In theory I think on the basis of 2 small experiments I tried! 1) I placed an infrared sensitive CCTV cameras with integrated infra-red LED lights behind a window to the outside area record. The IR light reflected from the glass and the picture unreadable. 2) If you have a camcorder or a webcam, set the camera up to look at yourself. Then point a TV remote at the camera and press a button. You will notice beams of infra-red light. (based on UK PAL video) My conclusion is: a) If a CCTV camera has an infra-red filter (for night vision), then an object bathed in infra-red light can cause enough light to cause or white spots of the object. Some cameras like Baxhall Hyper-D may be able to compensate. B) If even one house camcorder can see infrared light, then it may be possible for a normal camera to block vision through infra-red light directly into the lens, but it should be a constant power light beam.
