door alarms
Threshold breach detectors
Door alarms are security devices that sound when a door is opened, closed, or tampered with.
They range from simple battery-powered units that attach to residential doors to sophisticated systems integrated with commercial security networks.
The door alarm went off when the kids snuck out.
Some versions alert caregivers when patients with dementia attempt to wander.
