Overview
The Dahua ARD324-W2(S) Door Detector Plus is a wireless opening sensor with a built-in three-axis accelerometer. As well as reporting when a door or window opens, it can raise an alarm when the frame is struck or a window is tilted, sending events to a Dahua hub over 433 MHz radio. It suits a ground-floor window, glass door, safe, cabinet or roller shutter where an intruder might force or knock the frame before opening it, giving earlier warning than a plain magnetic contact.
Is it right for you?
- It suits openings that may be forced rather than simply opened, on a Dahua 433 MHz wireless alarm.
- It is for non-metal doors and indoor use only.
- If you only need open and close detection, the ARD323-W2(S) is the plain model.
Key features
- Reed switch for opening detection, triggering beyond about 40 mm of magnet gap.
- Shock detection with high, normal and low sensitivity settings.
- Tilt detection up to 25°.
- One external input for a normally closed, normally open or impulse-count wired detector.
- Up to 1,000 m open-space range with two-way, frequency-hopping, AES128 (Advanced Encryption Standard) encrypted radio.
- Temperature measurement from -15 to 65 °C, accurate to within 1 °C.
- Tamper alarm, low battery detection, test mode and cloud updates.
- One CR123A battery: about 3 years with the external input set to NO, 1.5 years set to NC, at two triggers a day.
What else you need
A Dahua 433 MHz wireless alarm hub such as the ARC3000H, the Dahua app for setting shock and tilt sensitivity, and one CR123A battery.
Installation
An alarm installer can fit it, and a confident owner can manage a home. Fix the body on the frame and the magnet on the door or window with the supplied bracket, keeping the gap under 40 mm when closed, then pair it in the Dahua app, set the shock sensitivity and test it by knocking the frame.
Software and licences
Shock sensitivity, tilt detection, zone type and test mode are set in the Dahua app. Firmware updates arrive through the cloud.
Before you buy
