Key Insights

The Geotab GO Focus Plus uses integrated ADAS and DMS rules to trigger near real-time video events. For Australian and New Zealand fleets, these rules are customised to suit heavy vehicle stopping distances and regional conditions, ensuring compliance with country-specific laws and requirements while reducing operational costs.

What are GO Focus Plus camera rules and thresholds?

A camera rule is a specific set of parameters that, when met, triggers a video event. These are categorised into Advanced Driver Assistance Systems (ADAS)—monitoring the road—and Driver Monitoring Systems (DMS)—monitoring the driver.

Rule thresholds control the sensitivity of these triggers. In Australia and New Zealand, a "one size fits all" approach fails due to our unique vehicle configurations:

  • Heavy Vehicles: For B-doubles or road trains, thresholds are set to detect tailgating much earlier. This accounts for the significantly longer stopping distances required compared to standard passenger cars.
  • Light Commercial Vehicles: For last-mile or metro delivery vans, thresholds may be adjusted to accommodate tighter traffic flow while still alerting to high-risk behaviours.

What are pre/post event buffers?

Buffers determine the start and end point of a recorded event.

  • Pre-buffer: Seconds recorded before the trigger.
  • Post-buffer: Seconds recorded after the trigger.

In rural Australian conditions, these buffers are critical. For example, if a driver swerves to avoid a kangaroo, the pre-buffer captures the animal entering the road, proving the driver's reaction was a necessary safety manoeuvre and not “erratic driving.”
