Its product portfolio spans camera systems (side, reverse, front, dome, and IP variants), Mobile Digital Video Recorders (Sentry S50 and S80), in-cab monitors, ultrasonic and radar sensors, audible alarms, and integrated safety systems. The company sells branded solution lines including SafetyStop Connexion™ (a patented auto-braking system), Fleet View (cloud-hosted telematics with live video and GPS tracking), Bike Hotspot (a cycling safety system), and a Low Bridge Detection System that uses AI camera-based road sign recognition with GPS verification. Its products are explicitly engineered to meet UK transport compliance regimes including FORS (Fleet Operators Recognition Scheme), DVS (Direct Vision Standard), and PSS (Progressive Safe System).

The company's business model combines one-time hardware sales, professional installation services performed by dedicated in-house UK engineers, ongoing maintenance and repair, and a growing recurring subscription revenue stream through Fleet View (delivered with a 4G SIM card package). Customers are primarily commercial fleet operators, local councils, and specialist vehicle operators across HGV, refuse collection, bus, van, road sweeper, industrial, and minibus segments. The company serves 1,000+ UK fleets directly through regional engineering teams and reaches international markets via distributor partners in Europe, North America, Asia, and Africa. Pricing is quote-based and not publicly disclosed. The company also operates adjacent compliance-driven sub-brands (SafetyStop, FleetView, Bike Hotspot) and maintains an in-house engineering and design function.
