Dahua Cameras

The Dahua DHI-ARD822-W2 is a dual-button wireless panic button for the Dahua AirShield alarm system. It needs both buttons pressed together to raise an alarm, which makes accidental activation far less likely — ideal for busy counters, schools or anywhere a single button could be knocked. The alert goes to your AirShield hub and your phone. It is IP54 rated, battery powered, and links to the hub over an encrypted 868 MHz two-way connection. An AirShield hub is required and sold separately.

Key points
- Two buttons pressed together raise the alarm — strong false-alarm prevention
- 868 MHz two-way radio with AES128 encryption and frequency hopping
- Range up to 1,200 m in open space to the hub
- IP54 rated; multi-status LED with battery level in the app
- CR2032 battery, around 3 years; wall-mount or portable
- Requires a Dahua AirShield hub

The Dahua DHI-ARM7011-W2 is a wireless relay for the Dahua AirShield alarm system. It gives the system a switched, isolated dry contact (0-36 VDC, up to 5 A) that you can trigger from the app, on a schedule, in a scene, or automatically when an alarm event happens — handy for switching a light, a gate or garage trigger, or an extra warning device. It links to the hub over an encrypted two-way radio link and has overheat and overvoltage protection built in. An AirShield hub is required and sold separately.

Key points
- One isolated dry-contact relay output, 0-36 VDC, up to 5 A
- Trigger from the app, a schedule, a scene or an alarm event
- Encrypted two-way radio with AES128 and frequency hopping; range up to 800 m
- Overheat and overvoltage protection; one tamper input
- Powered from 7-24 V DC; compact wall mount
- Requires a Dahua AirShield hub

The Dahua DHI-ARA43-W2 is a wireless alarm repeater for the Dahua AirShield system. It sits between the hub and your detectors and sirens, forwarding their signals to extend wireless coverage and remove blind spots in larger or awkward buildings. It supports up to 128 peripherals at up to 1,600 m in open space, switches automatically between dual antennas for a reliable link, and has a built-in battery that keeps it working for over 35 hours through a power cut. An AirShield hub is required and sold separately.

Key points
- Extends the hub-to-peripheral range up to 1,600 m in open space
- Provides a second path for up to 128 wireless peripherals
- Automatic dual-antenna switching to reduce signal blind spots
- 868 MHz two-way radio with AES128 encryption and frequency hopping
- Built-in lithium battery, over 35 hours of backup in a power cut
- Tamper alarm and external-power loss detection; needs an AirShield hub

The Dahua DHI-ARD912-W2 is a wireless water-leak detector for the Dahua AirShield alarm system. Place it on the floor by a washing machine, dishwasher, hot-water unit or under a sink and it raises an alarm the moment water reaches its sensor, so you catch a leak before it does real damage. Sensitivity is adjustable to suit the spot, the casing is IPX5 water-resistant, and it links to your AirShield hub over an encrypted 868 MHz two-way connection. An AirShield hub is required and sold separately.

Key points
- Alarms as soon as water reaches the sensor
- Adjustable sensitivity to suit the location
- IPX5 water-resistant casing; no wiring, easy to place
- 868 MHz two-way radio with AES128 encryption and frequency hopping
- Range up to 1,200 m in open space to the hub
- Temperature display and overheat alarm; CR123A battery, around 3 years

The Dahua DHI-ARD512-W2 is a wireless glass-break detector for the Dahua AirShield alarm system. It listens for the specific sound of breaking glass within about 9 metres and raises an alarm before an intruder is through the window, covering tempered, double-glazed, laminated, wired, plate and float glass. It links to your AirShield hub over an encrypted 868 MHz two-way connection and runs on a battery, so there is no wiring to run. An AirShield hub is required and sold separately.

Key points
- Acoustic glass-break detection up to 9 m, for most common glass types
- Dual-frequency listening with algorithms to cut false alarms
- 868 MHz two-way radio with AES128 encryption and frequency hopping
- Range up to 1,600 m in open space to the hub
- Two wired alarm inputs to add third-party detectors
- CR123A battery with around 3 years of life; tamper alarm; indoor use

The Dahua DHI-ARD821-W2 is a wireless panic button for the Dahua AirShield alarm system. One press raises an immediate emergency alarm — useful for intrusion, fire, a medical scare or any moment you need help fast — and the alert goes to your AirShield hub and your phone. It is IP54 rated, runs on a coin cell and can be wall-mounted or carried, talking to the hub over an encrypted 868 MHz two-way link. An AirShield hub is required and sold separately.

Key points
- One-touch panic / SOS button raises an immediate emergency alarm
- 868 MHz two-way radio with AES128 encryption and frequency hopping
- Range up to 1,200 m in open space to the hub
- IP54 rated; multi-status LED with battery level in the app
- Accidental-press prevention to avoid false alerts
- CR2032 battery, around 3 years; wall-mount or portable; needs an AirShield hub

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.

Key points
- Magnetic reed contact for doors and windows; triggers on opening when armed
- Real-time open/closed status of each door and window in the DMSS app
- Encrypted two-way RF link with frequency hopping; signal-strength check
- Tamper alarm, ambient temperature monitoring and low-battery warning
- Slim design for discreet mounting; magnet gap up to about 40 mm
- CR123A battery, around 3 years; indoor; requires an AirShield hub

The Dahua DHI-ARK30T-W2 is a wireless keypad for the Dahua AirShield alarm system. It lets people arm and disarm by entering a PIN or tapping an IC card by the door, with support for up to 32 users so you can give everyone their own code. It is fully wireless and links to your AirShield hub over an encrypted 868 MHz two-way connection, so there is no cabling to run. An AirShield hub is required and sold separately.

Key points
- Arm and disarm by PIN code or contactless IC card
- Supports up to 32 individual users
- Emergency alarm functions (panic, fire and medical) from the keypad
- 868 MHz two-way radio with AES128 encryption and frequency hopping
- Range up to 1,600 m in open space to the hub
- Four indicator lights for communication, arm/disarm, fault and alarm
