The Regulation-Ready Replacement for Wing Mirrors
The CMS31 replaces traditional physical wing mirrors with a camera-and-screen system that eliminates blind spots, improves visibility in poor weather, and meets the latest EU and UK regulatory requirements for commercial vehicle mirror systems — all while integrating AI safety features that a standard mirror simply can’t offer.
Why Fleets Are Moving to Camera Monitor Systems
Traditional mirrors have fixed, unavoidable blind spots — a major factor in pedestrian and cyclist collisions involving HGVs and buses. The CMS31 addresses this directly:
- Wider, clearer field of view than a physical mirror, with no blind spot at the mirror’s edge
- Reliable visibility in rain, snow, and fog — where physical mirrors are least effective
- 2-second fast start, with system latency as low as 50ms (60ms at 25°C)
- Self-cleaning camera module — automatic water spray and air jet keep the lens clear without driver intervention
- Built-in ultrasonic radar for additional collision warning
Built-In AI Safety Systems
The CMS31 goes beyond a passive camera feed, integrating three active safety systems:
- Blind Spot Information System (BSIS) — compliant with GSR ECE-R151
- Moving Off Information System (MOIS) — compliant with GSR ECE-R159, detecting pedestrians and cyclists as the vehicle moves off
- Blind Spot Monitoring (BSM) — includes door-opening warnings while parked and Blind Spot Detection (BSD) while driving
Full Regulatory Compliance
The CMS31 is built to meet the current wave of EU General Safety Regulation (GSR) requirements for commercial vehicles, alongside established mirror and vehicle standards:

Professional Installation Required
The CMS31 must be professionally installed to ensure correct operation and driver safety, and to avoid electric shock hazards, wiring damage, or reduced AI performance.
