Dahua DHI-ARD324-W2(S) Wireless Door Detector Plus
SKU: DHI-ARD324-W2(S)
Description
The Dahua DHI-ARD324-W2(S) is a Door Detector Plus for the Dahua AirShield alarm system. As well as sensing when a door or window is opened, it detects shock and tilt, so it catches someone forcing or lifting a door, not just opening it. It has a wired input for a third-party contact and even monitors temperature. It links to your AirShield hub over an encrypted two-way wireless connection and runs on a long-life battery, so there is no wiring to the hub. An AirShield hub is required and sold separately.
Key points
- Three sensors in one: open/close, shock, and tilt up to 25°
- Reed switch plus a triaxial accelerometer for accurate detection
- One wired alarm input for a third-party contact (NO/NC/impulse)
- Built-in temperature monitoring (-15 C to +65 C)
- Encrypted two-way wireless (AES128, frequency hopping), up to 1,000 m
- CR123A battery with up to around 3 years of life; tamper alarm
- Indoor use on non-metal doors; requires a Dahua AirShield hub

01Overview
What the DHI-ARD324-W2(S) is
The Dahua DHI-ARD324-W2(S) Door Detector Plus does more than a basic door contact. Fitted to a door or window, its reed switch reports open and close as you would expect, while a built-in triaxial accelerometer adds shock and tilt detection — so it can flag someone striking, prising or lifting the door, with adjustable shock sensitivity and a tilt alarm up to 25 degrees. It also has a wired alarm input, so you can bring a third-party contact into the same wireless point, and it monitors ambient temperature.
It is fully wireless to the hub. It connects over an encrypted two-way link with AES128 and frequency hopping at up to 1,000 m in open space, and a tamper alarm flags any attempt to remove it. A single CR123A battery runs it for up to around three years depending on how it is used, with a low-battery warning, and a test mode helps you confirm a good signal during setup.
Worth knowing before you buy: this is an indoor detector for non-metal doors and windows — it is not weatherproof and is not rated for outdoor or exposed positions. It is also an accessory, not a system on its own: it needs a Dahua AirShield hub, and you would normally pair it with a siren and a way to arm the system.

04Why choose this
Built for the way you actually use the DHI-ARD324-W2(S)
Bring in a wired contact
A wired input lets you add a third-party contact to the wireless system, handy for an existing reed or a roller door.
Years between battery changes
A CR123A cell lasts up to around three years with a low-battery warning, so upkeep is minimal.
Confirmed, secure link
An encrypted two-way wireless link with AES128 and frequency hopping confirms each report and resists interference.
05Where it fits
Right at home in these scenarios
Front and back doors
Protect main entry doors so any opening, shock or forcing raises the alarm through the hub.
Windows and sliding doors
Fit it to non-metal windows and sliders where tilt and shock detection add cover beyond a simple open/close contact.
Add an existing contact
Use the wired input to bring an existing reed switch or roller-door contact into the AirShield system.
Rooms worth watching
Use the temperature reading to keep an eye on a sensitive indoor room alongside door protection.
06Setup
Installation & setup
-
01
What's in the box
One DHI-ARD324-W2(S) Door Detector Plus with mounting bracket and a CR123A battery. A Dahua AirShield hub is required and not included.
-
02
Installation requirements
Mount it on the indoor face of a non-metal door or window with the magnet aligned to the marked gap, fit the battery and enrol it to your AirShield hub in the DMSS app. Set the shock and tilt sensitivity to suit the door, wire any third-party contact to the input, and use the test mode to confirm a good two-way signal before arming.
08Questions
Frequently asked about the DHI-ARD324-W2(S)
Q.01
Does the ARD324-W2(S) detector work on its own?
No. It is a detector for the Dahua AirShield system and needs an AirShield hub. Enrolled to a hub it reports door events wirelessly and the hub raises the alarm; on its own it has nothing to report to.
Q.02
How is the Plus different from a basic door contact?
A basic contact only tells you a door is open or closed. The Plus adds a triaxial accelerometer, so it also detects shock and tilt — catching someone striking, forcing or lifting the door — and it includes a wired input and temperature monitoring as well.
Q.03
Can I use it outside or in a weather-exposed spot?
No. It is an indoor detector for non-metal doors and windows and is not weatherproof or rated for outdoor use. For an exposed opening you would use a detector designed for that, or mount this one on the inner face of an indoor door.
Q.04
What is the wired input for?
It has one wired alarm input that lets you connect a third-party contact, such as an existing reed or a roller-door switch, and bring it into the AirShield system through this detector's wireless link, set as normally-open, normally-closed or impulse count.
Q.05
Why does it measure temperature?
It reports the ambient indoor temperature in the app, from -15 C to +65 C, which is handy for keeping an eye on a room as well as protecting the door. It is a monitoring feature, not a heat or smoke alarm.
Q.06
How long does the battery last and can I replace it?
It runs on a single CR123A cell for up to around three years depending on how often it is triggered and how the wired input is configured, with a low-battery warning. CR123A is a standard type you can replace yourself.
Q.07
Will someone be able to remove it without setting off the alarm?
No. It has a tamper alarm that triggers if the detector is removed or interfered with, so an attempt to take it off the door is reported to the hub.
Q.08
Is this genuine Australian Dahua stock?
Yes. It is supplied as genuine Australian Dahua stock with local 3-year warranty and support, and it pairs with the AirShield hubs and peripherals sold here.
Buying from Smarket
Is your Hikvision, Dahua, HiLook and TP-Link VIGI stock genuine Australian stock?
Yes, 100%. Every Hikvision, Dahua, HiLook and TP-Link VIGI product we sell is a genuine Australian-market model sourced through Australian supply chains — never grey imports. That means factory-sealed units, Australian-region firmware that works with the official apps out of the box, and a full 3-year local warranty.
How long does delivery take?
Metro delivery usually takes 2–4 business days after dispatch, and regional areas may take longer. You'll receive a tracking number by email as soon as your order leaves the warehouse.
How much is shipping?
Standard shipping is free on all orders over $300 AUD, Australia-wide. Orders under $300 ship at a flat rate of $25, calculated at checkout. Tracking is included on every order.
What warranty do you offer?
All cameras, NVRs and DVRs come with a 3-year back-to-base manufacturer warranty covering defects in materials and workmanship, in addition to your rights under Australian Consumer Law. Hard drives and accessories are covered as set out in our Warranty Policy.
What is your return policy?
You have 30 days from the day you receive your order to request a change-of-mind return. Items must be unopened, factory-sealed and in resalable condition. A 15% restocking fee applies and return postage is at your cost. Faulty or incorrectly supplied items are different: we cover the return shipping and refund or replace at no charge. Read the full Return & Refund Policy.

Add sirens
Make a triggered alarm heard with an ARA12-W2 indoor siren indoors and an ARA13-W2 outdoor siren outside.
Add more detection
Cover rooms and other openings with a ARD1233-W2 PIR detector, a ARD512-W2 glass-break detector or another ARD323-W2 door detector.
Add ways to arm
Arm and disarm with the ARK30T-W2 keypad or the ARA24-W2 keyfob.
