An aerial view of a two-lane forest highway shows a long queue of stopped trucks and vans backed up in one direction, with two dark cars pulled onto the right shoulder and a few people standing on the shoulder beside them. The camera descends closer over successive frames, revealing the stopped truck convoy, skid-like marks on the pavement, and the small group of people gathered next to the two shoulder-parked cars while the opposite lane still carries moving traffic.

Customer challenges
Footage is reviewed after a crash is reported, not understood as it happens
Legacy AI cannot judge crash type, severity, injuries or whether responders have arrived
Debris, stalled vehicles and uncovered loads in view are not recognised until a secondary crash
Dangerous-goods and uncovered gravel trucks are not identified or tracked across cameras
Agencies receive separate calls with no shared scene understanding
Incident timelines and evidence are compiled by hand from scattered footage
Customer benefits
