PIR motion array sensor

Hi! I need a passive infrared motion sensor array. I found this in internet http://wearcam.org/safebath/toilets/
The page says they are using EXISTech's PIR array. I need something like this. Can you tell me where I can get one of these?
Thanks!

If you goggle "PIR motion sensor relay", you should get plenty of hits.

Yes! But I need to buy it, not to see how it works or how it`s made. I need a manifacturer or store where I can find it.
Thanks!

go to any alarm installation or electrical wholesaler company... they should also be readily available on eBay
