Overview
The Dahua ARD2235 is a wired indoor motion detector that checks movement two ways before raising an alarm. A passive infrared (PIR) sensor and a microwave sensor feed an algorithm that confirms real movement, so heat from a heater or air conditioner does not trip it on its own. It suits kitchens, server rooms, warehouses, workshops and air-conditioned offices on a wired alarm panel.
Is it right for you?
- Choose it for rooms where a plain PIR would give false alarms: kitchens, server rooms, warehouses, workshops and rooms with heaters or air conditioning.
- Pets up to 25 kg are ignored, so it suits homes with a dog.
- For an ordinary room without heat sources, the simpler ARD1233 is enough.
- Microwave energy passes through thin walls and glass, so it is less suited to a room next to a busy corridor unless aimed carefully.
Key features
- PIR plus microwave detection, 12 m across 90 degrees.
- AND or OR logic between the two sensors, a dynamic threshold and 1P or 2P pulse count, so the installer can tune it for the room.
- Pet immunity up to 25 kg.
- White light resistance up to 6,500 lux and two-way digital temperature compensation.
- Alarm output NC or NO rated 60 V DC, 400 mA, plus a normally closed (NC) case tamper output rated 28 V DC, 100 mA.
- Red, green and yellow indicator for walk testing.
- 9 to 16 V DC supply, drawing 30 mA or less at 12 V DC.
- White ABS housing, 60 x 46 x 120 mm, 165 g.
What else you need
A wired alarm panel with a spare zone, such as the Dahua ARC2008C-V3 or ARC2016C-V3, powering the detector from its auxiliary output.
Alarm cable for power, the alarm output and the tamper output.
Installation
An alarm installer should fit, wire and walk-test it. It mounts on a wall.
Aim it away from doors to corridors and from moving machinery or fans, because the microwave sensor sees through thin walls and glass.
Before you buy
Indoor use, from -10 to 55 °C and up to 95% humidity.
The AND/OR logic, pulse count and sensitivity are set on the detector, so decide the settings with your installer.

Questions about this product
What does dual technology mean?
It has both a PIR sensor and a microwave sensor. With AND logic, both must detect movement before the alarm output switches, which cuts false alarms from heat sources.
Does it ignore pets?
Yes, pets up to 25 kg are ignored.
What power does it need?
9 to 16 V DC, 30 mA or less at 12 V DC, usually from the alarm panel's auxiliary output.
Which panels does it work with?
Any wired panel with a spare zone, such as the Dahua ARC2008C-V3 or ARC2016C-V3.
Can it be used outdoors?
No, it is an indoor detector rated from -10 to 55 °C.
