Dual-Tech Detector
HiLook HA-ALARM-PIR2 Dual-Tech Detector — Australian Stock & 3-Year Warranty
The HiLook HA-ALARM-PIR2 is a wired dual-technology motion detector that combines a passive infrared (PIR) sensor with a 24 GHz K-band microwave sensor. A target must be confirmed by both technologies before the detector alarms, which dramatically reduces false triggers from heat, draughts and reflections — making it the smart choice for tricky rooms where a standard PIR struggles. It covers up to 12 m at 85.9° across a 52-zone 3D optics array with no dead angle.
Built for demanding environments, the PIR2 offers pet immunity up to 30 kg, automatic sensitivity, digital temperature compensation, sealed optics against insects and IFT technology to head off interference-driven false alarms. Selectable EOL resistors and 9–16 V wide-voltage input with reverse-polarity protection make wiring straightforward on the HiLook AX Hybrid Pro panel, reporting through the hub to the Hik-Connect app. Backed by genuine Australian stock and a 3-year warranty.
Detection Range
12 m · 85.9°
Two Technologies, One Confident Alarm
PIR + 24 GHz Microwave
Dual-tech detection requires both the infrared and K-band microwave sensors to agree before alarming — virtually eliminating false trips from heating vents, sunlight and air movement.
52-Zone 3D Optics
A 52-zone 3D Fresnel lens array delivers full coverage with no dead angle, including creep-zone protection for the area directly beneath the detector.
Pet Immunity to 30 kg
Ignores larger animals up to 30 kg, so even big dogs won't trigger the alarm — ideal for homes and yards with sizeable pets.
Stable in Harsh Rooms
Automatic sensitivity, digital temperature compensation, sealed anti-insect optics and IFT interference handling keep performance steady where ordinary PIRs false-alarm.

Frequently Asked Questions
What does "dual-tech" mean?
The detector uses both a PIR and a 24 GHz microwave sensor, and only alarms when both confirm a target — greatly reducing false alarms.
How far does it detect?
Up to 12 m at 85.9°, across a 52-zone 3D optics array with no dead angle.
Will my dog set it off?
No — it offers pet immunity up to 30 kg, so even large dogs won't trigger the alarm.
When should I choose this over the PIR1?
Choose the PIR2 for rooms prone to false alarms — near heaters, large windows or draughts — where dual-tech confirmation adds stability.
Which panel does it work with?
It pairs with the HiLook AX Hybrid Pro panel, with selectable EOL resistors for compatibility with most wired panels.
How high should I mount it?
Between 1.8 m and 2.4 m. Optional wall and ceiling brackets are available separately.
