Compliance

False positive rate (FPR)

A false positive is a detection raised when the condition being tested is absent. A true negative is a negative case correctly left unflagged. The false positive rate measures errors across those actual negative cases: FPR = FP / (FP + TN). Multiply by 100 to express it as a percentage. The test must define what counts as one case, such as a labelled driving interval, and how the reference outcome was established.

AI dash cam

An AI dash cam is a connected vehicle camera with enough on-device processing to run computer-vision models against the video stream in real time. Road-facing models typically cover following distance, lane departure and forward collision risk. Driver-facing models cover distraction, phone use, drowsiness, smoking and seatbelt use. The device decides which moments are worth keeping, saves a short clip either side of the trigger, and uploads it with the matching GPS and sensor data. The word AI describes where the analysis happens, not a difference in image quality.

ADAS (advanced driver assistance systems)

ADAS is the umbrella term for systems that sense the road environment and either warn the driver or intervene. In a passenger car this includes autonomous emergency braking and adaptive cruise control. In a fleet aftermarket camera it usually means warning only: the device detects a risk such as a short following distance, a lane departure or an imminent forward collision, and alerts the driver in the cab while flagging the event for review. ADAS is the outward counterpart to a driver monitoring system, which looks inward at the driver.

Video telematics

Video telematics combines road-facing and sometimes driver-facing camera footage with the telematics data recorded at the same moment: GPS position, speed, heading, acceleration and time. Traditional telematics tells you that a harsh braking event occurred at a location and a speed. Video telematics shows you what was in front of the vehicle when it happened. Most systems record continuously to local storage and upload only short clips around a triggered event, because uploading every minute of footage over a mobile network is neither affordable nor useful.

Fleet safety camera

A fleet safety camera differs from a consumer dash cam in management rather than optics. It is centrally provisioned, connected over a mobile network, tied to a vehicle record, and configured from a platform rather than a device menu. Footage handling, retention and access are set once for the fleet. Most units are dual-facing, combining an outward ADAS view with an inward driver monitoring view, and most carry GPS so events arrive with position and speed attached.

Harsh braking

Harsh braking is one of a small family of accelerometer-derived driving events, alongside harsh acceleration and harsh cornering. A telematics device measures the rate of change in speed and raises an event when it crosses a threshold set in the platform. Thresholds are configurable, which means the same driving can produce very different event counts on two systems, and event counts are not comparable between vendors unless the thresholds are known.

Chain of Responsibility (CoR)

Chain of responsibility (CoR) is a principle in Australia’s Heavy Vehicle National Law that makes every party who influences a transport task legally accountable for safety, not only the driver. Parties such as operators, schedulers, consignors, consignees, loaders, and packers each have a duty to ensure, so far as is reasonably practicable, the safety of their transport activities. It applies to risks like fatigue, speed, mass, dimension, and load restraint.

Fatigue Management

Fatigue management is the practice of controlling the risk that tired drivers pose to road safety. For fatigue-regulated heavy vehicles in Australia, it involves complying with work and rest hour limits, keeping accurate records such as a work diary, planning realistic schedules, and recognising the signs of fatigue. It is part of the chain of responsibility, so the duty extends beyond drivers to operators and schedulers.
