Automated Noise & Speed Enforcement Solutions
From Insights to Action: Smarter Roads, Quieter Communities
Vehicle noise pollution, illegal exhaust modifications, and speeding disrupt local communities and endanger public safety. Traditional enforcement tools cannot isolate a single loud vehicle on a busy road, leaving local authorities with noise complaints but no actionable data.
The Truvelo Acoustic Monitoring System changes the game. By combining environmental monitoring with targeted education, our smart, connected outstations help authorities understand noise patterns and educate drivers.
Coming Soon
We are expanding our outstation capabilities to integrate radar speed detection and ghost plate cameras. This update will transform our monitoring zones into complete enforcement locations, delivering fully actionable evidence directly to the police.
Technical Ecosystem: Multi-Sensor Intelligent Mapping
Our future-proof solution combines multi-lane acoustic tracking with advanced visual imaging to remove all subjectivity from road monitoring.
Key Technical Features:
- Visual Sound Heatmaps: The system generates a high-definition JPEG and video clip overlaid with an acoustic heatmap, proving exactly which vehicle caused the noise disruption.
- Speed & Noise Syncing: Edge-processing technology syncs noise levels from the acoustic monitoring microphone array with vehicle speed data and registration plates at the exact millisecond of the event.
- Ghost Plate Detection: Upcoming camera upgrades will spot and bypass deceptive, reflective, or altered "ghost" plates, ensuring absolute vehicle identification.
- Pre-Integrated Cloud Pipelines: Fully compatible with core Vehicle Management Systems (VMS) and national offence databases like the NEC PENTIP Cloud for seamless escalation.
Proven in the Field: The Hertfordshire Success Story
Truvelo technology powers the UK’s leading county-wide acoustic monitoring initiative. Deployed by Hertfordshire Constabulary and the Hertfordshire Police and Crime Commissioner (PCC) along the strategic A405 and A414 corridors, our outstations successfully track illegal street racing and anti-social driving.
With the legal noise limit for new cars sitting at 72 dB (dropping to 68 dB), our systems successfully isolate extreme environmental offences:
- 96.2 dB captured from a modified sports car—operating at 100x louder than the standard vehicle baseline.
- 91.8 dB captured from an anti-social motorcycle rider—operating at 63x louder than the standard vehicle baseline.

| Vehicle
Type | Sound
Level | Acoustic Scale | Perceived Noise |
| New Car Standard | 68-72 dBA | Baseline (1x) | Baseline (x1) |
| Anti-Social Motorcycle | 91.86 dBA | 63x louder than baseline | Over 5 human perception |
| Modified Sports Car | 96.21 dBA | 100x louder than baseline | Over 6 human perception |
Our visual heatmap telemetry gives Hertfordshire authorities the definitive data needed to back their "education first" strategy, issuing warning letters to change motorist behaviour before moving to strict vehicle seizures.
Flexible, Scalable Deployment
Our hardware blends seamlessly into existing urban and highway infrastructure, adapting easily to your specific local hotspots.
- Adaptive Coverage: At a standard 4-metre mounting height, a single outstation reliably monitors an 8x8 metre area. For wide multi-lane junctions, mounting at 8 metres extends the coverage zone up to 16x16 metres.
- Optimal Alignment: Highly responsive brackets allow an exact 45-degree array tilt with a 70-degree microphone field of view to eliminate blind spots.
- Remote Management: A secure, browser-based dashboard gives engineering and enforcement teams the power to adjust decibel trigger thresholds remotely.
