Home experiment: Infrared remote control

In this video, which is aimed at KS4 pupils, you can see an infrared remote control. The remote control is pointed at the camera and a button is pressed. You can see the signal from the remote control, even though it would be invisible if you were to look at it with your eyes directly. The camera used is sensitive to infrared and so shows it up on screen. Pupils may be able to repeat this experiment at home, although some cameras include infrared filters to reduce glare from sunlight, so it may not show up properly.
