Overview
The Dahua ARD512-W2 is a wireless glass-break detector. An omnidirectional microphone listens for the sound pattern of breaking glass, and an on-board algorithm separates it from everyday noise before the detector signals a Dahua alarm hub over 433 MHz radio. Use it to protect a shopfront, glass partition, large window or sliding door where an intruder may break the glass rather than open the frame. One detector can cover several panes within its range.
Is it right for you?
- It suits a shop, showroom or office with large glazed areas, on a Dahua 433 MHz wireless alarm.
- It covers glass from 0.3 x 0.3 m up to 3 x 3 m, 2.4 to 6.4 mm thick, within 9 m.
- Curtains and blinds can dampen the sound, so it needs a clear path to the glass.
- For a wired panel, the ARD511 is the wired equivalent.
- Indoor use only, -10 to 55 °C.
Key features
- Detection range up to 9 m.
- Recognises tempered, double-glazed, laminated, wired, plate and float glass, 2.4 to 6.4 mm thick.
- Covers glass panes from 0.3 x 0.3 m up to 3 x 3 m.
- Two external inputs (normally open or normally closed) for adding wired contacts.
- 1,200 m open-space radio range with frequency hopping and AES128 (Advanced Encryption Standard) encryption.
- Tamper alarm, test mode and cloud updates.
- One CR123A battery: about 3 years with the external inputs in NO mode, about 1 year if both inputs are used in NC mode.
- Surface mounted, 107.8 x 34.5 x 24.8 mm, 45 g.
What else you need
A Dahua 433 MHz wireless hub such as the ARC3000H and one CR123A battery. Combine it with door contacts and motion detectors for layered protection.
Installation
An alarm installer can fit it. Mount it on a wall or ceiling within 9 m of the glass with a clear line to the panes, away from curtains and blinds, pair it in the Dahua app and use test mode to check the link.
Software and licences
Pairing, zone type and test mode are set in the Dahua app. Firmware updates arrive through the cloud.
Before you buy
- Mount it with a clear path to the glass; curtains and blinds reduce sensitivity.
- Battery life falls to about 1 year if both external inputs are used in NC mode.
- Indoor use only.
