Dahua DHI-ARD1233-W2 Wireless PIR Detector

SKU: DHI-ARD1233-W2
Description

The Dahua DHI-ARD1233-W2 is a wireless indoor PIR motion detector for the Dahua AirShield alarm system. It covers a 12-metre, 90-degree area, ignores pets up to 18 kg to cut false alarms, and reports to the hub over encrypted two-way 868 MHz wireless with a range of up to 1,600 metres in open space. It runs about four years on its battery and is part of a system, so it needs an AirShield hub to work.

01Overview

What the DHI-ARD1233-W2 is

The Dahua DHI-ARD1233-W2 is a wireless indoor PIR motion detector for the Dahua AirShield alarm range. Mounted on a wall at about 2.2 m, it covers a 12-metre area across a 90-degree spread, and its pet-immunity design ignores animals up to 18 kg so a dog or cat moving through the room does not set off the alarm. A dual-element low-noise PIR sensor with temperature compensation keeps detection steady across Australian summer and winter temperatures, and sensitivity is adjustable across three levels for the room it watches.

It talks to the AirShield hub over two-way 868 MHz wireless with AES128 encryption and frequency hopping, for a reliable encrypted link with a range of up to 1,600 metres in open space (less indoors through walls). Two-way communication means the hub confirms each message and the detector reports tamper and low-battery conditions, and it has a test mode and signal-strength check to make positioning easy during setup. It runs on a CR123A battery with roughly four years of life.

Two things to know: this is an indoor detector (rated for use from -10 to +55 °C, not weatherproof for outdoor mounting), and it is part of a system rather than a standalone alarm — it needs a Dahua AirShield hub to enrol to and report through.

04Why choose this

Built for the way you actually use the DHI-ARD1233-W2

Fewer false alarms

Pet immunity up to 18 kg and a dual-element sensor with temperature compensation cut the nuisance triggers that make people stop arming their alarm.

Secure, reliable wireless

Two-way 868 MHz with AES128 encryption and frequency hopping gives a confirmed, interference-resistant link to the hub, not one-way signalling.

Long battery life

Roughly four years on a CR123A battery with a low-battery warning means little maintenance and no surprise drop-outs.

Easy to place

A test mode and signal-strength check make it simple to find a spot with good coverage and a solid signal during setup.

05Where it fits

Right at home in these scenarios

Living areas and hallways

Cover a lounge, hallway or entry where intruders must pass, with pet immunity so the family dog does not trip it.

Homes with pets

Protect rooms a cat or small-to-medium dog uses, relying on the 18 kg pet immunity to avoid false alarms.

Small offices and shops

Add indoor motion coverage to an AirShield system for after-hours protection of a back room or floor.

Expanding an AirShield system

Add zones to an existing Dahua AirShield hub as you extend coverage room by room.

06Setup

Installation & setup

  1. What's in the box

    One DHI-ARD1233-W2 wireless PIR detector with a CR123A battery and wall-mount hardware. A Dahua AirShield hub is required and not included.

  2. Installation requirements

    Mount the detector on an indoor wall at about 2.2 m, aimed across the area to be covered and away from heat sources and direct sunlight. Enrol it to your Dahua AirShield hub through the app, set the sensitivity for the room, then use the test mode and signal-strength check to confirm coverage and a good wireless link before arming.

08Questions

Frequently asked about the DHI-ARD1233-W2

Q.01

Does the ARD1233-W2 work on its own?

No. It is a detector for the Dahua AirShield alarm system, not a standalone alarm. It enrols to a Dahua AirShield hub and reports motion to it, so you need an AirShield hub to use it. Once paired, the hub handles arming, alerts and any siren or app notifications.
Q.02

How big an area does it cover?

It detects motion over a 12-metre range across a 90-degree spread when mounted on a wall at about 2.2 metres. Aim it across the room rather than straight down a narrow corridor for the best coverage of an entry or living area.
Q.03

Will my pet set off the alarm?

It has pet immunity for animals up to 18 kg, so a typical dog or cat moving at floor level should not trigger it. Mount it at the recommended height and keep furniture that a pet can climb out of the detection path, since a pet up high and close to the sensor can still cause a trigger.
Q.04

How does it connect and is the link secure?

It uses two-way 868 MHz wireless to the AirShield hub with AES128 encryption and frequency hopping, so the signal is encrypted and resistant to interference. Open-space range is up to 1,600 metres; expect less indoors where walls and floors reduce it, and use the built-in signal-strength check to confirm a good position.
Q.05

How long does the battery last and how do I know when it is low?

It runs on a CR123A lithium battery with roughly four years of life under normal use. The detector sends a low-battery alarm to the hub well before it runs out, so you get warning to change the battery rather than losing coverage unexpectedly.
Q.06

Can I use it outside?

No. It is an indoor detector rated for use from -10 to +55 °C and is not weatherproof, so mount it inside. For an outdoor-style alarm trigger, use a detector designed for outdoor use such as an outdoor PIR or a PIR camera.
Q.07

Does it have a camera or record anything?

No. It is a motion sensor only, with no camera and no audio. If you want a detector that also captures an image of what triggered it, look at the AirShield PIR camera instead.
Q.08

Is it easy to set up?

Yes. It has a test mode and a signal-strength check that make it straightforward to position and confirm coverage during setup, and it enrols to the hub through the Dahua app. Mounting is a simple wall fix at the recommended height.
