The Dahua Wireless Door Detector combines a sensor and a magnet to monitor doors and windows. When armed, opening a door immediately triggers an alarm, and the system sends real-time notifications to the DMSS App, keeping users informed from anywhere.
Equipped with a tamper alarm, low battery warning, and test mode, this device ensures continuous, secure operation. Cloud update support allows for easy firmware upgrades, and the PC + ABS casing provides durability while remaining lightweight. It’s suitable for non-metal doors, with a detection distance of less than 40 mm (1.57″).
