What triggers video events in Reveal

Video recordings are uploaded to Reveal when unsafe driving behaviour (such as hard braking) is detected by the vehicle tracker (in real time) and AI Dashcam (in real time).

When a video is recorded, the AI software analyses the video by looking for objects near the vehicle (such as stop signs and road users) and by comparing the road speed with the speed of the vehicle.

When the AI detects multiple events happening around the same time, its classification level is based on the most severe incident.

Devices that detect events and triggers

All vehicles are fitted with a vehicle tracker. Video users have cameras fitted to the vehicle. This is either an AI Dashcam or road-facing camera (model 2). The AI software interacts with all camera types.

How detection works
  Vehicle trackers AI Dashcam AI software
What type of AI does it use? None Camera AI Cloud AI
Where is it? One the tracker On the AI Dashcam On a remote server
What does it do? The tracker triggers a harsh driving event based solely on factors such as speed and g-force. Camera AI constantly monitors driving behaviour, provides immediate feedback to drivers and triggers videos to be uploaded to Reveal. The cloud AI, also known as the video analytics engine, analyses the severity of an event after it has happened. At this time, it also recognises incidents such as Tailgating.
When does it run? After the harsh driving event. In real-time. It runs constantly, when the vehicle is on, to monitor driving behaviour. After the event. It analyses videos moments after it receives them from the camera.
What events can it detect?
  • Hard braking
  • Hard acceleration
  • Harsh cornering
  • Sudden force

Road-facing:

  • Tailgating
  • Pedestrian ahead

Driver-facing:

  • Tiredness
  • Distraction
  • Smoking
  • Phone call detection

Road-facing:

  • Tailgating
  • Rolling stop
  • Posted speed exceeded

Driver-facing:

  • Phone distraction
  • Seat belt unfastened

 
How does it affect classification? Moderate and severe classifications are applied to the harsh driving event only, not any other incidents that occurred before, during or after it.

Data from this AI considers what occurred before, during and after an incident, to feed into the overall classification system.

 

This is the AI that applies the classification as Critical, Major, Moderate, or Minor.

Events detected by the vehicle tracker

The following unsafe driving behaviours are detected by the vehicle tracker:

  • Hard acceleration

    • The vehicle speeds up suddenly (by more than 5 mph (8 km/h) per second).

    • The g-force is above 0.220g for at least 1 second.

  • Harsh cornering

    • The vehicle makes a harsh turn at speed.

    • The g-force is above 0.4g for at least 2 seconds.

  • Hard braking
    • The vehicle slows down suddenly (speed decreased by more than 6 mph (9.5 km/h) per second).
    • The g-force is above 0.265g for at least 1 second.
  • Sudden force
    • The vehicle jolts suddenly (caused by impact with a person, animal, or object, for example).
    • The g-force is above 0.7g for 0.1 second.
    • Sudden force is only detected by certain device models. Contact Support to find out whether your device can detect it.

Videos not triggering?

If videos are not appearing in the Video List, check whether a camera is working.
