Dahua DHI-ARD1731-W2(868) - Wireless PIR Motion Detector with Temperature Measurement

Dahua DHI-ARD1731-W2(868) — Wireless PIR Motion Detector with Temperature Measurement

The Dahua DHI-ARD1731-W2(868) is a wireless passive infrared (PIR) motion detector that also measures ambient temperature and captures a snapshot image whenever it detects an intrusion, giving visual confirmation of an alarm event rather than a motion trigger alone. It uses Dahua's RF-HD transmission technology to send images quickly and at high resolution, and communicates over the 868MHz band using frequency hopping and two-way communication for a stable link back to the alarm hub.

Who is it for?

This detector suits homes and small commercial premises using a Dahua wireless alarm system, where a straightforward motion sensor with picture-based alarm verification is wanted. The built-in temperature reading and snapshot capture make it useful anywhere a simple visual check of what triggered the alarm is helpful, without the cost or complexity of a full CCTV system.

Key specification

What you will need

• A compatible Dahua wireless alarm hub/control panel to pair the detector with and receive its alerts and images
• Batteries to power the detector (check the hub's compatible detector list before ordering)

Frequently asked questions

Does the ARD1731-W2(868) work on its own?

No. It is a wireless PIR detector that needs to be paired with a compatible Dahua wireless alarm hub/control panel to trigger alarms and deliver its images and notifications.

What does the temperature measurement feature do?

Alongside standard PIR motion detection, the detector reports the ambient temperature in the protected area, giving an extra data point alongside the alarm trigger.

Why does it take a snapshot image?

On detecting an intrusion, the detector captures a snapshot using Dahua's RF-HD transmission technology, so you get visual confirmation of the alarm event rather than a PIR trigger alone.

What frequency does this variant use?

This is the 868MHz version, matching the European wireless alarm frequency band used across the Dahua ARD wireless alarm range.
