Bill,
At Carnegie-Mellon University we augment our alarm systems with a
plastic fiber optic cable daisychained and passing through each piece of
computer equipment. The alarm trips when the fiber cable is broken ot
tampered with. This is in addition to other sensors (contacts/PIR
Motion). I believe it is called the "Light Guard" system and is
avialable from Security Systems of America (George Boranti 412
244-4900).
With technicaly advanced students you need to have a more technicaly
advanced alarm system to make defeating more difficult. Magnets on
contacts and masking PIRs can be more easily defeated if one knows what
they are doing.
