The most important factors are camera coverage (front, cab, sides, and rear), video quality (1080p HD minimum for road-facing), cellular connectivity with Store and Forward for long-haul routes, cloud retention length (TrackNet retains footage for 3 to 6 months, with incident clips retained longer on request), AI driver monitoring for coaching, and professional installation support for multi-camera configurations. GPS integration and a fleet management dashboard that ties video to location and driver data are also essential for claims defense and operational oversight.
