Door Sensor

This magnetic door sensor activates immediately once the door or window is pried open and the magnetic strips separate. It delivers zero-delay real-time on-site alert to deter intruders effectively. Unlike delayed linkage alarms, the standalone unit triggers sound right at the protected spot, creating immediate deterrence. It reliably detects tiny gaps from forced entry, offering sensitive and fast reaction for all entry points around your house.

Equipped with multi-level volume control including full treble loud mode and mute silent mode. The maximum 90dB loud alarm scares off thieves while silent mode lets you sleep peacefully without disturbance for late-night indoor access. You can switch volume freely to match different scenarios, balancing powerful burglary warning and quiet daily rest needs for families with kids.

Powered by two AA batteries, the sensor adopts ultra-low standby current design below 35μA to extend service lifespan drastically. It supports low voltage reminder to notify users for timely battery replacement. Without frequent power changes, it cuts maintenance trouble, ideal for long-term unattended monitoring on windows, storage cabinets and safes all year round.

Lightweight small-sized body fits all installation spots without occupying space. It works universally on room doors, glass windows, metal safes, storage drawers and cabinet doors for home, apartment, rental house and office use. No complicated matching host needed, single unit can independently guard any vulnerable entry to form a full coverage safety system.

Comes with strong 3M double-sided adhesive tape for punch-free mounting in seconds. Just peel off the sticker and attach the main sensor and magnetic strip on door frames, aligning them parallel within 2cm gap when closed. No wiring or professional technicians required, users finish DIY installation by themselves, no damage to walls, wood or glass surfaces.
