It has a filter on the front which stops the IR, and then a series of filters on the sensor chip itself to only allow one colour through to each sensor on the chip so they can detect different colours.When we just let IR into the camera by putting our filter on the front it will pass through all the coloured filters to slightly varying degrees, as these filters are not designed to stop it.This normally doesn't work because a diode is designed so that there are no free electrons to carry an electric current when you try and push electricity the wrong way.But if a photon of light with enough energy hits the middle of the diode it will knock an electron off a silicon atom which can now move and carry electric current.Then we look to identify ways to measure the campaign’s effectiveness through a Return on Investment analysis.In that way, you will know whether your money has been well spent.You are now looking for the IR filter this is a small piece of glass with a reddish or greenish tinge.If you are lucky it will just come off but in this case it is in front of the lens.
Your webcam has a sensor behind the lens which is sensitive to most colours of light and IR (and also ultra violet).
If you look at a light through a glass of cola it looks a very deep red, which tells you it's becoming more transparent at the red end of the spectrum, so we shouldn't be surprised that it transmits infra-red light.
In the IR you can see that the queen is not all there.
