What triggers video events in Reveal

Leer en Español

Video recordings are uploaded to Reveal when unsafe driving behavior (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 cloud AI analyzes 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 cloud AI detects multiple events happening around the same time, its classification level is based on the most severe incident.

How detection works

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 cloud AI interacts with all camera types.

 
  Vehicle tracker Camera AI Cloud AI
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 behavior, provides immediate feedback to drivers and triggers videos to be uploaded to Reveal. The cloud AI, also known as the video analytics engine, analyzes the severity of an event after it has happened. At this time, it also recognizes 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 behavior. After the event. It analyzes videos moments after it receives them from the camera.
What events can it detect?
  • Hard braking
  • Hard acceleration
  • Harsh cornering
  • Sudden force

Events detected by the vehicle tracker

The following unsafe driving behaviors 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.
