Sentinel Cameras™ Door Alarm

Sentinel Verified independent store

A wireless magnetic door and window alarm that guards an entry point around the clock. The moment the door or window opens and the magnetic contact separates, a built-in siren soun ds — waking the household and startling an intruder into leaving before they get any further. Instant detection. The magnetic sensor triggers the moment the contact breaks. No delay, no arming routine, no app — from the second it is installed, it is on guard. Loud enough to matter. Most break-ins end the moment a burglar knows they have been noticed. The siren makes sure everyone — inside the house and out — knows immediately. Installs in under five minutes. No wiring, no drilling, no tools. It attaches with the included double-sided adhesive, and the scale lines on the housing help you align the magnet correctly. Because there are no holes, it suits rentals, caravans, sheds and garages as well as houses. Completely wireless. Nothing to run, and nothing for an intruder to cut. In the box: 1 × door alarm unit and door magnet. Cover every way in — add one for each door or window you want protected. They work independently, so there is no hub, no pairing and no single point of failure. Show more
