Dahua DHI-ARD324-W2(868) — Wireless Door Detector Plus with Tilt and Shock Detection
The Dahua DHI-ARD324-W2(868) is a wireless door detector plus: a door sensor that goes beyond opening detection. Dahua says it detects the status of doors and windows, recognising when they are opening, shocking and tilting, and it displays the temperature of the surrounding environment with an overheating alarm. A wired detector can be connected as normally open, normally closed or pulse. It communicates on 868MHz as part of a Dahua wireless alarm system.
Also listed as ARD324-W2(868).
Key features
- Tilt and shock detection: generates an alarm when the event happens. Tilt up to 25°, shock sensitivity high, normal or low.
- Triaxial accelerometer and reed switch recognise a door or window opening, shocking and tilting; movement distance under 40 mm.
- Displays the temperature of the surrounding environment and supports an overheating alarm.
- One alarm input for a wired detector: normally closed, normally open or impulse count; configuration through the app.
- 868MHz two-way communication with AES128 encryption and frequency hopping, up to 1,200 m in open space; jamming detection supported.
- One CR123A battery: 3 years (external input type NO) or 1.5 years (NC) if triggered twice a day.
- Tamper and low battery detection, test mode, and cloud update with automatic restore if the update fails.

Common questions
What does the Plus version detect?
Dahua says it detects the status of doors and windows, recognising when they are opening, shocking and tilting, and it generates alarms when the event happens.
How do the tilt sensor and shock sensor work?
Dahua's datasheet lists a triaxial accelerometer alongside the reed switch. Tilt detection works up to 25° and shock detection has high, normal and low sensitivity levels.
Can I connect a wired detector?
Yes. It has one alarm input that can be used as normally closed, normally open or impulse count, and Dahua says all configurations can be done through the app.
Does it show the temperature?
Yes. It displays the temperature of the surrounding environment and supports an overheating alarm, with a measuring range of -15 °C to +65 °C indoors and ±1 °C accuracy.
Can I fit it to a metal door?
Dahua lists the scenario as non-metal doors, with a movement distance of under 40 mm.
How long does the battery last?
It uses one CR123A battery. If triggered twice a day with a battery efficiency of 70%, Dahua gives 3 years with the external input type NO and 1.5 years with NC.
Does it need an alarm hub?
It is a wireless detector that communicates two-way on 868.0 MHz-868.6 MHz, so use it with a Dahua 868MHz wireless alarm hub. The hub we stock is Dahua DHI-ARC3800H-FW2(868) 4G wireless alarm hub (868MHz).
