[Jeff Sandberg] demonstrates that ably with his project to use ancient 1990s burglar alarm sensors in his modern smarthome setup. The sensors in question are from an old GM Interlogix security system.

Intrusion detection devices must maintain a delicate balance. Highly sensitive devices can cause too many false alarms, while devices with insufficient sensitivity are easily defeated by sophisticated ...
