Overview
The Dahua ARD1233-W2 is a battery-powered passive infrared (PIR) motion detector for a Dahua wireless alarm. A dual-element, low-noise sensor watches for the body heat of a moving person and reports to the hub over two-way radio. It is the standard indoor motion sensor for a living room, corridor, shop, office or storeroom, covering a room corner to corner when mounted at 2.2 m, and it ignores pets up to 18 kg.
Is it right for you?
- It suits an ordinary indoor room on a Dahua 433 MHz wireless alarm.
- It suits a home with pets up to 18 kg.
- For a kitchen, server room or a room with heaters or air conditioning, where moving warm air can fool a PIR, the ARD2231-W2 dual-tech detector suits better.
- Indoor use only, -10 to 55 °C.
Key features
- Detection range 12 m with a 90° field of view at a 2.2 m mounting height.
- Pet immunity for animals up to 18 kg.
- Three adjustable sensitivity levels and two-way digital temperature compensation, so range holds up in a warm room.
- White light resistance up to 2,000 lux, to reduce false alarms from sunlight and headlights.
- Detects movement from 0.3 to 3 m/s.
- Frequency-hopping, AES128 (Advanced Encryption Standard) encrypted radio, up to 1,200 m in open space.
- Tamper alarm, signal strength check, test mode and cloud updates.
- One CR123A battery rated for about 4 years; 104 x 60 x 50 mm, 100 g, wall mounted.
What else you need
