Hi alfa88,
The Kaya PF filter blocks visible light but allows infra-red light to
pass through. Therefore, only infra-red light will reach the camera
sensor.
The CCD sensor in many camcorders and digital cameras responds to
infra-red light as well as visible light, but the dominant component
is normally the visible light. If the exposure level is increased by
about ten times, with the Kaya PE filter in place, the image formed by
the faint infra-red light will be recorded by the CCD sensor in the
camera.
Because infra-red waves pass through some materials quite easily, a
"see-through" image can be obtained as in these examples:

Kaya's site has a more detailed explanation here:
"How it works"

There is also a guide to choosing a compatible camera (click on
"devices" and "check cameras" on the left-hand panel).
