The tinfoil sheets do work if you take your time and move slowly, however, as PIR's work with the changing temperature, any part of your body that gets exposed risks setting off the alarm.Passive infra red (PIR) can be avoided with a survival bag from Millets. The foil absorbs your body heat, you can cut a little hole to see through and its a good laugh... but is no good with motion sensors as I recently discovered![]()

I have used a Survival Bag at St Joes and it works on about 4 sensors, it stopped working on the last sensor to get into the main chapel sadly, but we still got the shots we needed.
