Probe Alert Systems
Be alerted as soon as a vehicle enters.
Be alerted to movement of vehicles.
Our Probe Driveway Alert Systems are designed specifically to detect vehicles — and only vehicles — entering your driveway or private road. Using underground magnetic sensing technology, these systems provide accurate, reliable alerts without being triggered by people, animals, or weather.
Probe Product Specifications
Selective alerting of vehicles coming and going.
Coverage
Detects metallic motion up to 3metres from the probe.
Detection
Detects only vehicles. The directional probe will alert you to the direction of the vehicle.
Range
Up to 1.6km between sensor and receiver.
How the Probe system work
Unlike motion sensors that detect any movement, probe alert systems use magnetic detection to sense the presence of large metal objects, like cars or trucks.
A discreet probe is buried just below the surface alongside your driveway or access point. When a vehicle passes by or stops near the sensor, a wireless signal is sent to your indoor receiver, instantly alerting you.
The Directional Probe System
If you want to know whether a vehicle is arriving or leaving, our directional probe system is the perfect solution. It uses two buried sensors, spaced 1.2 metres apart, to detect the direction of movement. The system then triggers a distinct alert tone depending on whether the vehicle is entering or exiting your property.
Key Features & Benefits
Wireless & Easy to Install
Ignore pedestrians, stock and animals, and wind-blown branches. Only metal objects (like vehicles) will trigger the system.
Discreet Installation
The underground sensor stays out of sight and out of the way—ideal for properties where appearance matters.
Long Range Performance
With transmission distances of up to 1,600 metres (line of sight), you can monitor large driveways, farm entrances, or remote gates with confidence.
Weather Resistant Sensors
Designed to withstand rain, snow, and heat—ideal for New Zealand’s changing conditions.
Expandable System
