OK, PICs in security equipment?
The range of panels made by CADDX (USA) and sold in Australia as NX-4, NX-8 etc by Direct alarm Supplies are ALL built around PICs.
Also the range of PARADOX panels (Canada), sold in Australia by Security Merchants also are built around PICs.
Bound to be more out there that I don't know about 'cos I don't use them..
