Where does the risk come from on an aggregate site?
Human form recognition cameras for quarries and aggregate sites are built around one problem. Large plant works close to people who are hard to see. Human Form Recognition, or HFR, is AI camera technology trained to detect a person, rather than any object, near the machine and warn the operator straight away. There is a better chance of stopping before a near miss turns into something worse. Protection Végétale 360 is TrafficAngel’s HFR system. Keeping people on foot away from moving plant is the priority in HSE guidance on separating pedestrians and vehicles, and on a busy quarry that is not always simple.
Quarries, sand and gravel pits, and aggregate yards are noisy, dusty places that never stand still. Wheel loaders feed hoppers, dumpers run material between the face and the stockpiles, and excavators load out while workers walk the site to take samples, clear blockages, or check on plant. A loading shovel can have a large area behind and beside it that the operator simply cannot see, and a worker on foot can step into that area in seconds.

Why mirrors and reversing alarms only go so far
Standard kit still matters. Mirrors, reversing cameras, and reversing alarms all help. The trouble is that they do not always tell the operator the one thing they need to know in a hurry. Is there a person in the danger zone right now, and which side are they on? A reversing alarm warns everyone nearby that a machine is backing up, but it does nothing when the machine is creeping forward or slewing. A camera shows a view, but the operator has to be looking at the right screen at the right moment. On a busy aggregate site, that gap is where incidents happen. That is the gap human form recognition cameras is built to close. We work with all construction and travel sites including rail, warehouses,
What PlantShield 360 does on an aggregate site
Protection Végétale 360 uses up to four AI cameras around the machine, trained to pick out the human form inside zones you set. When someone enters a zone, the operator gets a clear warning on the in-cab LED display and an audio callout telling them which side the person is on.
There are two zones. The outer zone shows yellow with a callout such as “pedestrian left” or “pedestrian rear”, which tells the operator to slow down and check. The inner zone shows red and means stop. The logic is the same on every shift, so a stand-in driver reacts the same way as the regular operator. When the machine is parked, the system can warn on screen without the audio, which keeps the cab quieter when there is no movement.
It also works across a mixed fleet. A quarry runs several machine types at once, and each one has its own blind spots. Because the system can be set up to suit different machines and layouts, it is practical to fit across the plant you already run.
Solution To Aggregate Site Safety
Everyday situations on an aggregate site
A few moments come up again and again, and they are where PlantShield 360 does its most useful work.
A loading shovel turns away from the face to feed a hopper, and a worker steps in to clear a blockage just as the bucket swings back. A dump truck reverses towards a stockpile while someone is taking a sample or walking a haul road nearby. A tipper driver arrives to collect aggregate, climbs down at the loadout or weighbridge to sheet the load, and ends up on foot close to plant they do not work with every day. In each case the operator may have only a second of warning, and a person can be in the wrong place before anyone has registered it.
Visiting drivers are worth singling out, because hauliers coming in to tip or collect do not know the site the way the regular team does and are not always where an operator expects them to be. A system that watches for the human form around the machine, rather than relying on everyone following the same routine, helps cover that gap.
Building a fuller picture with recording and alerts
Detection is the first job. Knowing what happened afterwards is the second. Human form recognition cameras for quarries and aggregate sites can be paired with DVR recording and live video through LiveDrive, plus email or SMS alerts and a safe-approach feature that uses a visible thumbs-up signal. For a site manager, that means footage to review after a near miss, a way to check in remotely, and a record that supports toolbox talks and incident reviews. A single in-cab warning becomes something the whole site can learn from.

Why human form recognition cameras for quarries and aggregate sites is worth fitting
Installing human form recognition cameras for quarries and aggregate sites really earns its place because it deals with the risk that is hardest to control by training and planning alone, a person on foot in the wrong place at the wrong second. It does not replace good site rules, banksmen, or driver skill. It backs them up at the moment they are most likely to fail.
The mineral products industry treats the vehicle and pedestrian interface as one of its most serious hazards, and the priority is always to keep the two apart through site design. Traffic management plans, one-way haul roads, and marked pedestrian routes do most of the work of keeping plant and people apart, and PlantShield 360 adds a warning for the times someone ends up outside those routes. Used alongside inductions and toolbox talks, the same yellow and red logic gives operators, yard staff, and visiting drivers one consistent signal to act on.

Foire aux questions
It is an AI camera system that detects the human form around a machine and warns the operator when someone enters a set zone. TrafficAngel supplies this as PlantShield 360, using up to four cameras to cover the area around plant such as wheel loaders, excavators, and dumpers on a quarry or aggregate site.
A reversing camera shows a view and a proximity alarm tells you something is near. PlantShield 360 detects the human form in set zones and tells the operator which side the person is on, with yellow for caution and red for stop.
The cameras are made for demanding commercial environments. As with any camera, keeping the lenses clean is part of normal upkeep, and TrafficAngel provides service and aftersales support to keep systems working reliably.
Yes. It can be paired with DVR recording and live video through LiveDrive, so you can review footage after an incident and use it for training.
No. The two-zone setup is built to flag real risk rather than every movement, and when the machine is stationary, the system can warn on screen without sounding in the cab.
