Login to buy
The HiLook HA-ALARM-PIR2 is a commercial-grade wired dual-technology intrusion detector that integrates a passive infrared (PIR) sensor with a 24 GHz K-band microwave module. Requiring simultaneous verification from both detection technologies before triggering an alarm, it significantly eliminates false alerts caused by rapid thermal changes, air currents, and reflective surfaces—making it the ideal motion sensor for challenging environments where single-technology PIRs falter. Delivering up to 12 meters of coverage across an 85.9-degree angle via a 52-zone 3D optical lens system, it ensures comprehensive space monitoring with zero blind spots. Featuring 30kg pet immunity, automated sensitivity adjustment, dynamic digital temperature compensation, insect-proof optics sealing, and Independent Floating Threshold (IFT) technology, it maintains stable operation against environmental interference. Equipped with integrated selectable end-of-line (EOL) resistors and a 9–16V wide DC power input with reverse-polarity protection, wiring to HiLook AX Hybrid Pro panels and compatible hardwired alarm hubs is direct and reliable, reporting events seamlessly to Hik-Connect. Sourced through Total Security Equipment, it comes supported by genuine Australian stock and a 3-year warranty.

- Description
Product Overview
The HA-ALARM-PIR2 acts as an ultra-reliable motion detection solution for residential and commercial hardwired security setups. Engineered to excel in environments prone to environmental interference, it delivers precise volumetric protection across complex indoor layouts.
Featuring combined PIR and 24 GHz K-band microwave detection, this unit prevents false triggers from HVAC vents, drafty corridors, and large windows. Its 52-zone 3D optics layout provides total coverage with zero dead angles, while built-in 30kg pet immunity allows large pets to move freely without disrupting armed zones. Sourced via Total Security Equipment, it offers professionals an essential, highly stable intrusion detection sensor.
Key Capabilities
Dual-Tech Detection (PIR + 24 GHz)
Combines passive infrared and 24 GHz K-band microwave technology, requiring both sensors to confirm intruder presence before issuing an alarm signal.
12m Range & 85.9° Field of View
Provides reliable volumetric coverage across mid-to-large interior areas, reducing the total sensor count required to protect open room layouts.
30kg Pet Immunity
Ignores household pets weighing up to 30kg, permitting medium and large dogs to roam indoors without generating unwanted alarm trips.
52-Zone 3D Optics & Creep Protection
Engineered with a 52-zone 3D optical lens array that eliminates coverage gaps, including downward creep-zone optics for space right below the unit.
Onboard EOL Resistor Selection
Features selectable DIP switches for alarm and tamper EOL resistors, simplifying wiring integration with HiLook AX Hybrid Pro and third-party mainboards.
Best For
Perfect for rooms near air conditioners, heating vents, or sunlit window fronts where standard PIRs trigger false alarms.
30kg pet filtration allows homes with substantial pets to stay fully guarded without false activations.
Seamlessly pairs as a wired zone input with HiLook AX Hybrid Pro panels for remote app reporting via Hik-Connect.
Built-in EOL options speed up site deployment when replacing legacy sensors on existing hardwired control boards.
Why Choose the HiLook HA-ALARM-PIR2
When traditional motion detectors struggle with thermal turbulence, air movement, or direct sunlight, the HA-ALARM-PIR2 provides superior stability through dual-technology verification. Combining PIR detection with 24 GHz K-band microwave sensing, an alarm is verified only when both detectors trigger simultaneously. Enhanced with 3D 52-zone Fresnel optics, automated sensitivity tuning, IFT noise rejection, and sealed anti-bug optics, it maintains consistent accuracy regardless of room conditions. Sourced through Total Security Equipment, it represents a dependable solution for sites requiring high-reliability intrusion detection.

Ideal Use Cases
Drafty & High-Airflow Areas
Dual-tech confirmation ensures heating units, ceiling fans, and moving air currents will not cause false alarms when spaces are armed.
Residences with Large Pets
30kg pet immunity keeps interior alarm zones active without triggering when large dogs move through monitored living spaces.
Commercial Windows & Sunrooms
Microwave confirmation prevents solar heat surges across expansive glass panels from generating accidental intrusion alerts.
High-Security Open Areas
52 optical zones plus zero-dead-angle creep-zone optics ensure intruders cannot sneak below or around detection fields.
Wired AX Hybrid Pro Expansions
Integrates directly as a hardwired zone on HiLook AX Hybrid Pro mainboards, delivering real-time alert notifications to the Hik-Connect mobile app.
Choosing the Right Model
Choose this model if:
You require a hardwired dual-tech (PIR + 24 GHz microwave) motion detector with 12m reach, 30kg pet immunity, and selectable EOL options for challenging thermal environments.
Choose the PIR1 detector if:
Your site features stable environmental conditions without significant thermal shifts, requires up to 18m reach, and only needs pet immunity for animals under 10kg.
Choose a different detector if:
You require an outdoor-rated weatherproof sensor or a completely cable-free wireless detector for your alarm panel hub.
Frequently Asked Questions
What does "dual-tech" mean on the HA-ALARM-PIR2?
Dual-tech means the sensor combines both a PIR module and a 24 GHz microwave module. An alarm is generated only when both technologies detect movement simultaneously, drastically lowering false alerts.
What is the total coverage distance and angle?
It monitors up to 12 meters at an 85.9-degree angle across a 52-zone 3D optics layout designed with zero dead angles.
Will large pets trigger false alarms on this detector?
No. The HA-ALARM-PIR2 features pet immunity up to 30kg, preventing larger domestic dogs from activating armed zones.
When should I pick the PIR2 over the standard PIR1?
Select the PIR2 for rooms prone to temperature fluctuations or drafts—such as near heaters, large windows, or AC units—where dual-technology confirmation ensures superior zone stability.
Which mainboards and panels are supported?
It connects natively to HiLook AX Hybrid Pro panels, while selectable built-in EOL resistor settings maintain compatibility across standard wired alarm mainboards.
What is the recommended installation height?
Mount the detector between 1.8m and 2.4m above the floor. Dedicated wall and ceiling brackets are available separately if required.
Where is this product sourced and what warranty is included?
The HA-ALARM-PIR2 is supplied via Total Security Equipment with authentic local Australian stock and a 3-year warranty.
