Overview
The Dahua ARD1731-W2 is a wireless motion detector with a small still camera. When it senses movement it takes JPEG snapshots and sends them to the Dahua alarm hub, so you can look at the pictures in the app and decide whether to call for help. It suits homes, shops and offices where you want to check an alarm before acting, without recording video all the time.
Is it right for you?
- Choose it for a hallway, living room, shop floor or back office where a snapshot on alarm is useful.
- It only takes pictures when the alarm triggers, so it suits rooms where continuous CCTV is not wanted.
- Pets up to 18 kg are ignored.
- It is for indoor use only. For a yard or garden with pictures on alarm, see the outdoor ARD2251E-W2(V).
- If you do not need pictures, a plain motion detector such as the ARD2231-W2 (B) is simpler.
Key features
- PIR detection to 12 m across 86 degrees when mounted at 2.2 m, with 18 kg pet immunity.
- Snapshots from 320 x 240 up to 1600 x 1200 pixels, with an 88 degree horizontal field of view.
- Infrared illumination to 12 m, switching between colour and black-and-white, so pictures work in the dark.
- Pictures upload over a 2.4 GHz RF-HD link for speed, while alarms go over the two-way 433 MHz radio.
- AES128 encryption, frequency hopping and a tamper alarm.
- Three sensitivity levels and two-way digital temperature compensation.
- Three CR123A batteries, rated for about 4 years at two triggers a week.
- Cloud updates and low battery detection through the hub.
What else you need
A Dahua wireless alarm hub that supports PIR cameras. The ARC3000H supports up to 8 of them.
Three CR123A batteries.
The Dahua app, where snapshots are viewed and the detector is configured.
Installation
An alarm installer should fit and pair it. It wall mounts at 2.2 m, the height the 12 m range is specified at.
The picture upload link has a shorter range than the alarm radio: up to 300 m in open space at high speed, against 1,200 m for alarms. Check placement against the hub before fixing it.
Before you buy
Indoor use only, from -10 to 55 °C.
Frequent triggering shortens battery life; the 4-year rating assumes two triggers a week.
Pictures are still images, not video.
