Alarm

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
- Two-colour status LED confirms normal or fault feedback
- CR2032 battery with around 3 years of life and low-battery warning
- Compact 60 mm keyring fob; works only with a Dahua AirShield hub

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

The Hikvision DS-PDTT15AM-LM is a wired outdoor tri-tech motion detector that combines dual passive-infrared sensors with a 24 GHz microwave sensor and tri-signal logic to catch intruders while filtering out false alarms. It adds active anti-masking, 40 kg pet immunity and an IP65 weatherproof housing, and connects by cable to a normally-closed zone on any wired or hybrid alarm panel.

Key points
- Wired outdoor tri-tech detector: dual PIR + 24 GHz microwave
- Tri-signal logic cross-checks all three sensors to cut false alarms
- Active anti-masking detects spray, cover or blocking attempts
- 15 m range, 90° @ 180° adjustable, 92 detection zones
- Pet immunity up to 40 kg; IP65 weatherproof
- Normally-closed output for any wired or hybrid alarm panel (12 VDC)

The Hikvision DS-PM1-I16O2-WB is an AX PRO wireless multi-I/O expander that lets you keep existing wired detectors when you move to a Hikvision AX PRO wireless alarm. It connects up to sixteen hardwired inputs and two outputs and reports them back to the wireless hub over Tri-X radio - so legacy cabling and sensors stay in use instead of being replaced.

At a glance
- Integrates up to 16 wired alarm inputs and 2 outputs into an AX PRO wireless system
- Tri-X two-way 433MHz radio to the hub, up to 800m open-air, AES-128 secured
- Each zone independently set to NO/NC, EOL or DEOL for professional wired sensors
- Mains powered 100-240 VAC, takes a 12V 7Ah backup battery for up to 36 hours
- For AX PRO wireless hubs - not for the DS-PHA64 hardwired panel

The Hikvision DS-PM2-S(AU) is a 3G/4G communication module that adds cellular reporting to a Hikvision AX Hybrid Pro alarm panel. With a SIM fitted, the panel can send alarms and notifications over the mobile network - useful where there is no phone line, or as a resilient backup to a wired internet path.

At a glance
- Adds 3G/4G cellular alarm reporting to AX Hybrid Pro hardwired panels
- AU variant: LTE-FDD B1/B3/B5/B7/B8/B28/B66, LTE-TDD B40, WCDMA and GSM
- SIM card slot - a suitable SIM and mobile coverage are required
- Plug-in module design for neat installation inside the panel
