The Dahua DHI-ARD324-W2(868S) is the small version of Dahua's AirShield Wireless Door Detector Plus. As well as reporting when a door or window opens, its triaxial accelerometer detects shock and tilt, so it can raise an alarm if someone tries to force a window or lift a cover. A wired input lets you connect another detector, and it reports the surrounding temperature with an overheating alarm. It differs from the standard-size DHI-ARD324-W2(868) by its smaller housing.
Windows, slim door frames, patio doors and skylights on an AirShield alarm, where you want open, shock and tilt detection from one small device.
