Eyes on everyblind spot.
Flexible proximity warning systems for any vehicle. Workers wear a tag, machines carry the sensors, and both get a warning the moment someone steps into a danger zone.
Most site fatalities involving machines happen at walking pace, inside a few metres, in a spot the operator simply cannot see.
Mirrors and reversing beepers help, but people stop hearing alarms that sound all day. A proximity warning and alerting system works differently. It knows exactly who is near the machine and how close they are, and it only speaks up when it matters.
Our PWAS uses ultra-wideband (UWB) radio to measure the distance between a machine and every tagged worker to within centimetres, in any light, through dust and around corners. Radar and AI cameras add detection for people or objects without a tag.
The system is hardware agnostic and retrofits to almost any vehicle, old or new, of any brand. Typical installs take two to four hours per machine with no permanent modification to the cab.
Tag. Detect.Alert. Report.
Four things happen in under a tenth of a second, every time a person and a machine get too close.
Wear the tag
Each worker carries a small rechargeable UWB tag on a helmet clip, vest or lanyard. It vibrates and beeps when they are in danger.
Sense the distance
Anchors on the machine range every tag many times per second. Radar and cameras watch for untagged people and obstacles.
Warn both sides
The operator sees and hears the warning in the cab. The worker feels it on the tag. Optional relays can slow or stop the machine.
Learn from it
Every event is logged with time, machine, tag and distance. Dashboards show hotspots so you can fix the layout, not just the symptom.
Calm untilit matters.
Each machine gets its own zones, measured from its edge and set during commissioning. Alerts get louder only as people get closer.
Aware
Every tag and object nearby is tracked and logged. No alarm, so operators are never distracted by people at a safe distance.
Heads up
The cab display shows who is close and where. A soft tone sounds and the worker's tag vibrates.
Act now
A loud alarm in the cab and on the tag. An optional relay can slow or stop the machine automatically.
The right sensorfor each hazard.
No single technology fits every site. We combine them based on the machine, the environment and how people move around it.
UWB tag ranging
Centimetre accuracy, works through dust, darkness and around corners. The backbone of person to machine detection.
Radar sensors
Detects any object, tagged or not, in rear and side blind spots. Ideal for reversing trucks and loaders.
AI pedestrian camera
On-board vision that recognises people and ignores clutter, with a live view on the cab display.
Vehicle to vehicle
Machines see each other too, so haul trucks and light vehicles get warned at blind intersections.
Speed & zone control
Geofenced areas can limit speed in walkways, loading docks or near offices, automatically.

Asked on almost every site visit.
Will it work on our older machines?
Yes. The system is brand agnostic and only needs a 12 or 24 volt supply. We have fitted it to machines over twenty years old alongside brand new fleets.
Won't operators just ignore another alarm?
Alarm fatigue happens when warnings sound all the time. Because PWAS knows the real distance, it stays silent until someone is actually inside a zone, so alerts carry weight.
What about visitors without a tag?
Radar and AI cameras cover people without tags. Most sites also keep a stock of visitor tags at the gate, which we can supply and manage.
