Prioritize coverage that matches the vehicle's biggest blind spots. A truck camera system commonly needs strong side and rear visibility. A bus camera system may require exterior and passenger-area views. A van camera system should cover reversing and road evidence without unnecessary hardware. Position each commercial vehicle camera so body panels, doors, or equipment do not block the image. A fleet camera system should use repeatable mounting positions across similar vehicles. Test the truck camera system, bus camera system, and van camera system during turning and reversing. Check every commercial vehicle camera in daylight and darkness. A standardized fleet camera system simplifies maintenance. Finalize the truck camera system, bus camera system, van camera system, commercial vehicle camera, and fleet camera system only after blind-spot testing.
