A clear signal that closes the gap between the operator and the pedestrian
Digital Thumbs Up for plant machinery is a pedestrian-facing safety signal that we supply as part of our Protector Vegetal 360 setup. It puts a clear visual cue on the outside of the machine so a pedestrian, banksman or ground worker can tell at a glance whether to wait, or whether the operator has confirmed it is safe to come forward. We supply and fit vehicle safety systems for plant and site operators, and this is the part of that work that deals with the moment of communication, not just detection. A detection system tells the operator that someone is there. This tells the person on the ground that they have been seen.
The problem is rarely that nobody looked
On a working site, the operator is usually doing everything right. They are checking the monitor, watching the mirrors and working through their pre-move routine. The weak point is what the person on the ground actually knows. From outside a loader or a telehandler, it is hard to tell whether the operator has clocked you, whether the machine is about to move, or whether you are clear to step across.
People end up guessing, and they often guess in the second or two before a machine moves off. That guess is where a lot of near misses on site start. A camera system warns the operator, but on its own it does not tell the pedestrian anything. Digital Thumbs Up for plant machinery is built to fill that second half of the exchange.

What Digital Thumbs Up Does
The system consist of a round display fitted to the outside of the machine, in a position a pedestrian can see. By default it shows a red stop. When the operator has stopped, and immobilize the vehicle completely, checked the area and judged that it is safe, they press a single button inside the cab and the display changes to a green thumbs up. The pedestrian gets a plain, familiar signal. Red means hold back. Green means the operator has seen you and it is safe to approach. There is nothing for the person on the ground to interpret, and nothing complicated for the operator to do. Run as part of PlantShield 360, AI cameras watch the area around the machine and pick up human forms inside the zones set for that vehicle. The operator gets a clear visual, and where needed audible, alert in the cab. The external display then lets them turn that awareness into a signal the pedestrian can actually read.
How Digital Thumbs Up Works In Practice
1. The operator checks the mirrors
The operator runs their normal pre-move checks, using the mirrors and any sensors fitted to the machine.
4. The pedestrian gets a clear acknowledgement
The external display confirms the operator has seen them. The pedestrian, banksman or ground worker can read the signal at a glance and knows where they stand.
2. The operator identifies the pedestrian
PlantShield 360 helps the operator pick up a pedestrian, banksman or ground worker in the area around the machine, so they know someone is close before anything moves.
5. Everyone moves on safely
Once the green thumbs up is showing and the operator is satisfied it is safe, the pedestrian can approach or pass and work carries on.
3. The operator triggers Digital Thumbs Up
With the machine stopped and the area checked, the operator presses the in-cab button and the external display changes from a red stop to a green thumbs up on the outside of the machine.
Where Digital Thumbs Up makes the most difference
Anywhere people and machines share the same ground, a signal like this earns its place. It tends to matter most around forklifts, telehandlers, loading shovels, dumpers and excavators, on sites where someone is regularly on foot near a working machine. In practice that means construction sites, builders’ merchant yards, warehouses and distribution yards, recycling and waste sites, and manufacturing and production areas. The common thread is shared ground, blind spots and movement that does not stop for long. In those conditions, a clear stop or go signal on the side of the machine gives everyone the same reference point to work from.
Testimonials
The PlantShield 360 System and HFR Camera System have made a measurable difference to safety and operational awareness across our site. With heavy forklift movement and multiple high‑risk pedestrian zones, we needed a robust solution that would enhance visibility, reduce blind‑spot hazards, and support our wider commitment to safe, efficient operations.
The integrated AI‑driven camera setup, combined with real‑time driver alerts and high‑quality video recording, has significantly improved how our operators manage pedestrian proximity, particularly around busy production outputs, stacked materials, and restricted‑visibility areas. The external cameras reliably detect pedestrians in high‑risk spaces, while the internal monitoring system helps reinforce positive driver behaviours and supports targeted coaching where needed.
The installation quality was exceptional. Despite space limitations in the vehicle cab and challenging cable‑routing pathways, the TrafficAngel team delivered a clean, professional fit with optimised camera placement, precise ECU and DVR mounting, and secure antenna positioning. Their attention to detail resulted in a reliable, durable system that integrates seamlessly with our daily operations.
Since implementation, we have seen enhanced driver confidence, improved pedestrian safety, y clearer visibility around heavy loads and blind spots. The recorded footage has already proven valuable for incident review, training, and continuous improvement. The PlantShield 360 System has become a key part of our risk‑reduction strategy and is a solution we would strongly recommend to any high‑activity industrial operation looking to strengthen its safety performance.
“The PlantShield 360 and HFR camera system have transformed safety on our site. The AI-driven pedestrian detection, clear driver alerts, and high-quality video recording have noticeably improved visibility around blind spots and high-risk areas. Installation was exceptionally professional, and the system integrates seamlessly with our daily operations. It’s a reliable, intelligent safety solution that delivers real value from day one.”
Why a visual signal works where a shout or a wave does not
Plant sites are loud. Engines, reversing alarms, tools and general noise make spoken instructions unreliable, and a wave from inside a cab is easy to miss or misread from the ground. A visual signal does not depend on the pedestrian hearing anything or reading a hand gesture through glass. The Health and Safety Executive has long flagged workplace transport, and the point where people and vehicles meet, as one of the most serious risks on site. A clear, consistent signal is a practical way to take some of the guesswork out of that meeting point.
Where Digital Thumbs Up fits in a wider plant safety setup
We supply Digital Thumbs Up as a standalone product or as part of a broader plant safety build. On most machines it is offered as a safe-approach add-on for PlantShield 360, where it works with Human Form Recognition cameras to support clearer communication between operators and ground workers. It also sits alongside the cameras, sensors, monitors and alarms we already fit to plant and site vehicles, and the in-cab side of that is covered in how PlantShield 360 improves operator awareness on site.
This matters because pedestrian safety around plant is rarely one product doing one job. It is a layered setup, where each piece of equipment closes a gap that the others cannot fully cover.

ContáctenosFrequently Asked Questions
It is an optional feature that works as part of the PlantShield 360 setup. The AI cameras and in-cab alerts handle detection, and the external display adds the pedestrian-facing signal on top.
Yes. The signal does not replace mirrors, cameras or the operator’s own judgement. The operator checks the area first, then uses the display to confirm to the pedestrian that it is safe to approach.
A round display on the side of the machine showing either a red stop or a green thumbs up. Red means wait. Green means the operator has seen you and confirmed it is safe to come forward.
It can be suitable for forklifts, telehandlers, loaders, dumpers, excavators and other plant and yard vehicles. The best way to confirm fit for your machines is to talk it through with us.
That is where a visual signal is most useful. When noise makes audible warnings and spoken instructions hard to rely on, a clear stop or go signal gives the pedestrian something they can read at a glance.
Operators get a simple way to communicate outside the cab, pedestrians and banksmen get a clear cue, and site safety managers get a practical, easy-to-explain measure they can build into inductions and daily routines.
