What triggers videos and in-cab alerts

AI Dashcams can detect unsafe driving behaviours and notify drivers with in-cab audio alerts. These prompts are designed to encourage safer driving over time.

Caution

Your company is obligated to let drivers know what video data is captured about them. Share this article with your drivers so they know what information is generated by the camera, stored in Reveal, and what it is used for.

Driver-facing triggers

The driver-facing camera analyses a driver’s head position, and their interaction with objects, such as cell phones. If the driver’s behaviour is outside of its normal range for too long, the camera may classify it as unsafe driving behaviour, and trigger an in-cab alert.

The AI then classifies the event, and a video is uploaded to Reveal.

The camera calibrates the driver’s head position during the first 30 seconds of a journey and every 30 minutes after that. The AI calibration can be disrupted if the driver is:

  • Wearing glasses, a hat, or a mask

  • Frequently touching their face

Tiredness

When the driver becomes sleepy.

The driver yawns and/or closes their eyes for at least 2 seconds.

The vehicle must be travelling over 25 mph (40 km/h).

Distraction

When the driver is not focusing on the road.

The driver looks away from the road for at least 2 seconds.

The vehicle must be travelling over 25 mph (40 km/h).

Activates if behaviour persists.

Smoking

When the driver is smoking while driving. This includes electronic cigarettes.

The driver holds the shape of a cigarette close to their face for at least 2 seconds.

The vehicle must be travelling over 25 mph (40 km/h).

Phone call detection

When a driver handles a cell phone to make or receive a call while driving.

The driver holds the shape of a phone to their face for at least 5 seconds while driving.

The vehicle must be travelling over 25 mph (40 km/h).

Road-facing triggers

The road-facing camera monitors driving behaviour and the vehicle’s proximity to other road users.

The type of lens that the camera is fitted with can affect how close and how fast objects appear.

Tailgating

The vehicle is dangerously close to the vehicle in front. The driver does not have enough time to stop if the vehicle in front slows down.

The vehicle in front may have entered the driver’s lane suddenly, or the driver got too close due to unsafe driving.

The vehicle must be travelling over 37 mph (60 km/h).

Note

Even if tailgating videos are disabled in your AI driving assistance settings, videos triggered by other events will be analysed and tailgating may be detected. This is because the AI can detect tailgating after the event.

Preview of second audio alert

Activates if behaviour persists.

Pedestrian ahead

The vehicle is close to a pedestrian or cyclist.

The vehicle must be travelling 6-18 mph (10-29 km/h).

How to prevent videos falsely triggering

Videos can be falsely triggered, usually when an AI Dashcam lens is obstructed or in the wrong position.
