Hi All
My PIC based alarm system have been blown up with a High Voltage
zapper; those handheld units for shocking people/animals...
Aparently this is a new craze among burgulars. Thy kill home alarms,
car alarms and cct video with these zappers.

Short of using screen cable for every sensor, is there other devices
or goodies that can protect alarm systems from this assult????

Regards
Cassie
