The Dahua DHI-ARD1731-W2 is an indoor wireless PIR motion detector with a built-in camera, part of the Dahua AirShield wireless alarm range. When it detects movement it captures and sends a burst of HD snapshots to your Dahua alarm hub and phone, so you can visually confirm whether an alarm is a real intruder or a false trigger before you act.

Key points
- Indoor PIR detector with built-in 2MP camera (snapshots up to 1600 × 1200)
- Sends up to 6 HD images in about 10 seconds for visual alarm verification
- 12 m detection range, 88° horizontal coverage; pet immunity up to 18 kg
- Two-way encrypted wireless (AES128) with frequency hopping; tamper alarm
- Battery powered (3 × CR123A), about 4 years typical life
- Requires a Dahua AirShield wireless alarm hub (sold separately)

The Dahua DHI-ARC3000H-FW2 is the wireless hub at the centre of a Dahua AirShield alarm system. It manages your wireless detectors, sirens, keypads and keyfobs, decides when to raise an alarm and notifies you through the free DMSS app. It connects three ways — Ethernet, Wi-Fi and 4G cellular — so it keeps reporting even if one network drops, and a built-in rechargeable battery keeps it running through a power cut. Wireless peripherals are required and sold separately.

Key points
- Central hub for the AirShield system; up to 150 wireless peripherals
- Supports up to 6 sirens, 64 keyfobs, 8 keypads, 8 PIR cameras and 4 repeaters
- Triple connectivity: Ethernet (RJ45), Wi-Fi 2.4G and 4G cellular (dual SIM)
- Built-in rechargeable battery for around 12 hours of backup in a power cut
- Encrypted two-way wireless to peripherals (AES128, frequency hopping)
- Alarm video verification with IP cameras; app push, SMS and phone-call alerts to up to 5 numbers
- Self-monitor free in DMSS with no monthly fees; wireless peripherals sold separately

The Dahua DHI-ARA13-W2 is a weatherproof wireless outdoor siren for the Dahua AirShield alarm system. It combines a high-output sounder of up to 110 dB with a bright flashing strobe, so a triggered alarm is both heard and seen from outside the property. Its IP65 housing stands up to dust and rain, 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
- High-output siren up to 110 dB at 1 m, plus a flashing strobe
- Multiple alarm tones (intrusion, fire, panic and more)
- IP65 weatherproof housing; outdoor use from -25 C to +60 C
- 868 MHz two-way radio with AES128 encryption and frequency hopping
- Range up to 1,600 m in open space to the hub
- Powered by 4 x CR123A batteries or 9-15 V DC; tamper alarm
- Requires a Dahua AirShield hub

These Dahua Blue Mifare Tags are the proximity tags (part code DHI-ARK30T-W2-IC) for the Dahua ARK30T-W2 AirShield wireless keypad. Each tag is a contactless Mifare card that a user simply taps on the keypad to arm or disarm the alarm — no PIN to remember, and you can give each person their own tag. They are passive RFID tags with no battery, and they only work with the ARK30T-W2 keypad, which is sold separately.

Key points
- Blue Mifare proximity tags for the Dahua ARK30T-W2 AirShield keypad
- Tap to arm and disarm — no PIN code needed
- Give each household member or staffer their own tag
- Contactless Mifare RFID; passive, no battery
- Easily enrolled and removed in the DMSS app
- Requires the ARK30T-W2 keypad (and an AirShield hub)

The Dahua DHI-ARA12-W2 is a wireless indoor siren for the Dahua AirShield alarm system. When the system is triggered it sounds a loud alarm of up to 84 dB to startle an intruder and alert anyone inside, with three volume levels so you can match it to the room. It links to your AirShield hub over an encrypted 868 MHz two-way connection and runs on batteries, so there is no wiring to run. An AirShield hub is required and sold separately.

Key points
- Loud indoor alarm up to 84 dB at 1 m, with three selectable volume levels
- 868 MHz two-way radio with AES128 encryption and frequency hopping
- Range up to 1,000 m in open space to the hub
- Tamper alarm, test mode and low-battery warning built in
- Runs on 2 x CR123A batteries, around 2.5 years of life
- Bracket-mounted; indoor use; requires a Dahua AirShield hub

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.

Key points
- Indoor wireless PIR detector for the Dahua AirShield alarm system
- 12 m detection at 90° from a 2.2 m mounting height; pet immunity up to 18 kg
- Dual-element PIR with temperature compensation and 3 sensitivity levels
- 868 MHz two-way wireless, AES128 encryption, frequency hopping, up to 1,600 m open-space range
- CR123A battery with roughly 4-year life; tamper and low-battery alarms
- Wall mount, 104 x 60 x 50 mm; requires an AirShield hub (sold separately)

The Dahua DHI-ARA24-W2 is a four-button wireless keyfob for the Dahua AirShield alarm system. It lets you arm and disarm your alarm from your pocket and includes a dedicated SOS button to raise an emergency alert. It talks to your AirShield hub over an encrypted 868 MHz two-way link, so the keyfob confirms each command rather than firing blind. An AirShield hub is required and sold separately.

Key points
- Four buttons: Home arm, Away arm, Disarm and SOS emergency alarm
- 868 MHz two-way radio with AES128 encryption and frequency hopping
- Range up to 900 m in open space to the hub
