i took a remote control, aiming at my camera and look at the LCD screen on my camera. my camera sees the IR light from the remote control. but it seems that almost all cameras, my phone camera and web cam, they all take in IR.
i read from some places that devices like web cam, they sometimes block away IR with some filter. but why do cameras block IR?
it seems to me that most camera devices, camera, handphone and web cam, they all allow IR to go in.
