Any advice for a door tamper alarm for an isolated site? The idea is to
sense that someone is trying to gain unlawful entry before they actually
open the door, thus providing additional time to respond. In the case of
only a door entry alarm, valuable time is lost trying to verify if the entry
is legitamite.
Unlawful entry would be via drilling a hole through the door to get to a
deadbolt latch, or a shock sensor if the door lock (say a Unican) was being
smashed off. Issue with the shock sensor is that it would have to ignore
the door slamming shut, which seems to rule out the piezo stick-on variety.
Perhaps the second or third whack with a sledge hammer would set off the
alarm?
All reasonable ideas appreciated. Cost is a factor, since there are many
doors that require this solution in my application.
