Dahua DHI-ARD323-W2(S) Wireless Door Detector
SKU: DHI-ARD323-W2(S)
Description
The Dahua DHI-ARD323-W2(S) is a wireless magnetic door and window detector for the Dahua AirShield alarm system. A sensor and a separate magnet sit on the door (or window) and its frame; when the door is opened while the system is armed, the magnet moves away from the sensor and the alarm is triggered. You can see the live open or closed state of every door and window in the DMSS app. It links to the hub over an encrypted two-way RF connection and runs on a battery. An AirShield hub is required and sold separately.

01Overview
What the DHI-ARD323-W2(S) is
The Dahua DHI-ARD323-W2(S) guards a door or window on a Dahua AirShield alarm. It is a two-piece magnetic contact: a sensor body on the frame and a small magnet on the moving door or window. While the system is armed, opening the door separates the magnet from the sensor and raises the alarm at the hub and on your phone. Even when disarmed, the DMSS app shows whether each protected door or window is open or closed, which is handy for a quick check that the house is shut up.
It is built to be easy to live with. The slim casing mounts discreetly on most door and window frames, the reed contact responds when the magnet moves more than about 40 mm away, and it carries a tamper alarm, signal-strength detection, ambient temperature monitoring and a low-battery warning. The link to the hub is two-way with frequency hopping and AES128 encryption, so it stays connected and protected.
Two honest notes. It is designed for non-metal doors and frames — a metal surface weakens the magnetic field, so on a metal door you fit non-metal spacers or use the small-magnet option. And like every AirShield device it needs a hub to work; confirm the detector's RF band matches your AirShield hub when you order. A single CR123A cell runs it for around four years with a low-battery warning, and it is genuine Australian Dahua stock with local 3-year warranty and support.

Discreet and simple
A slim two-piece design mounts neatly on most frames with no wiring and a several-year battery.
Secure two-way link
Frequency hopping and AES128 encryption over a two-way radio link keep it connected and protected.
05Where it fits
Right at home in these scenarios
Front and back doors
Fit one to each external door so any opening while armed raises the alarm immediately.
Windows on the ground floor
Protect accessible windows where a contact catches the opening before someone is inside.
Internal doors to valuables
Add one to a study, store or garage internal door for an extra layer around what matters most.
Check-before-arm routine
Use the live status in the app to make sure every door and window is closed before arming away.
06Setup
Installation & setup
-
01
What's in the box
One DHI-ARD323-W2(S) door detector (sensor plus magnet) with a CR123A battery and mounting hardware. A Dahua AirShield hub is required and not included.
-
02
Installation requirements
Mount the sensor on the fixed frame and the magnet on the moving door or window, aligned and close together when shut. On metal frames add non-metal spacers. Enrol it to your AirShield hub in the DMSS app, then open and close the door to confirm it reports and the signal to the hub is good before relying on it.
08Questions
Frequently asked about the DHI-ARD323-W2(S)
Q.01
How does the ARD323-W2 detect a door opening?
It is a two-part magnetic contact. The sensor body sits on the frame and a magnet sits on the door or window; when the door opens and the magnet moves more than about 40 mm away, the reed switch opens and, if the system is armed, the hub raises the alarm.
Q.02
Does it work on its own?
No. It is a detector for the Dahua AirShield system and needs an AirShield hub. The hub receives the open signal and handles the alarm and notifications, so on its own the contact has nothing to report to.
Q.03
Can I use it on a metal door or window frame?
It is designed for non-metal doors and frames. Metal weakens the magnetic field, so on an aluminium or steel frame you fit non-metal spacers to lift the sensor and magnet off the metal, or use the small-magnet option, and keep the gap within range.
Q.04
Can I see whether a door is open in the app?
Yes. The DMSS app shows the live open or closed state of each protected door and window, even when the system is disarmed, so you can check at a glance that everything is shut before you arm or leave.
Q.05
What gap between the sensor and magnet still works?
The contact stays closed until the magnet moves more than roughly 40 mm from the sensor, so a normal door or window movement triggers it cleanly. Mount the two pieces aligned and close together when the door is shut.
Q.06
Will it match my AirShield hub?
It pairs with the Dahua AirShield hub over the same secure two-way link as the other peripherals. RF bands are region specific, so confirm the detector's band matches your hub when you order.
Q.07
How long does the battery last?
It runs on a single CR123A cell for around four years in typical use, with a low-battery warning before it runs out. CR123A is a standard cell that you can replace yourself.
Q.08
Is this genuine Australian Dahua stock?
Yes. It is supplied as genuine Australian Dahua stock with local 3-year warranty and support, matching the AirShield hubs and peripherals sold here.

Pair it with an AirShield hub (required)
The detector needs a hub to work — build your system on the DHI-ARC3800H-FW2 Alarm Hub 2, or the smaller DHI-ARC3000H-FW2 hub.
Add motion and glass cover
Layer it with a ARD1233-W2 PIR detector and a ARD512-W2 glass-break detector so you are alerted on movement and at the glass as well as on an opened door.
Arm and sound the system
Add an ARK30T-W2 keypad for arming and an ARA12-W2 indoor siren so a break-in is heard.
Want a ready-made system?
Start from a bundled AirShield starter kit and add door contacts where you need them.
