PPE detection
PPE detection is the automatic check, performed on a camera image, of whether a person in frame is wearing the required personal protective equipment - most often a helmet, a high-visibility vest, safety glasses or gloves. A vision model evaluates every frame and reports only those situations where an item required in that particular zone is missing.
Computer vision
Computer vision is the field in which software interprets images on its own: recognising what is in the frame, where it is and what it is doing. In industrial use this means turning a camera stream into a record of events that can be acted upon, instead of footage somebody has to watch.
Edge AI
Edge AI means performing analysis on a device located where the data is produced, instead of sending it to a remote data centre. In vision systems the video is analysed on site, and at most event information leaves the premises.
Hazardous zone
A hazardous zone is a designated area of a plant where being present carries increased risk - a machine's working envelope, a forklift route, the vicinity of a furnace, an area of work at height. In a vision system the zone is a polygon drawn on the camera image, with a rule attached: who may be inside it and when.
Video analytics
Video analytics is the automatic processing of camera images to detect events and collect numerical data about what happens in the observed area. The output is not footage but a record of events and indicators that can be compared over time and between areas of a plant.
RTSP
RTSP (Real Time Streaming Protocol) controls the delivery of audio and video in real time. In industrial practice it is the way an IP camera exposes its image to other software - a recorder, a video management system or an analytics engine.
ONVIF
ONVIF is an open standard describing how video surveillance devices from different manufacturers communicate. It covers device discovery on the network, stream retrieval, pan-tilt-zoom control and event reading.
Fall detection
Fall detection is the recognition, from a camera image, of a situation where a person has ended up lying down and does not get up within a set time. The system judges not the moment of the fall but what follows it - a lack of movement over some seconds separates a collapse from crouching.
Video smoke detection
Video smoke detection is the recognition of the characteristic movement and change in air transparency within a camera view that indicate smoke. The method works at a distance and does not require smoke to reach a measurement point, which sets it apart from a point detector.
Anti-collision system
An anti-collision system warns when a vehicle approaches a person or another vehicle, and in some deployments limits the machine's speed. In the vision variant a camera mounted on the truck recognises a pedestrian in the path of travel and signals this to the operator.
VMS
A VMS (Video Management System) is software that manages cameras, recording, user permissions and live viewing. It ensures footage is recorded, retained for the required period and available when it needs to be replayed.
Object detection model
An object detection model is a program trained to indicate which objects appear in an image and where. The output is a list of boxes with an assigned class and confidence value, for example person, helmet, forklift.
False alarm
A false alarm is a report of an event that did not actually occur. In safety systems it is a more serious problem than an occasional miss, because it erodes operators' trust in every subsequent report.
Video monitoring and GDPR
An image in which a person can be recognised is personal data, so video monitoring falls under data protection law. Vision analytics does not change that principle, but its scope and processing method affect the risk assessment and the employer's obligations.
RTLS
RTLS (Real Time Location System) determines the current position of people, vehicles or equipment across a site. It answers where something is now and, combined with history, how it moved there.
Near miss
A near miss is a situation in which a hazard occurred but nobody was hurt - a pedestrian passed a forklift by a metre, someone entered a machine zone while it happened to be stopped. Statistically such situations are many times more frequent than accidents, so they reveal risk far earlier.
Lone working
Lone working means performing tasks in a place where the worker stays out of sight and hearing of others. The risk lies not in the incident itself but in the time that passes before anyone notices it.
Visual leak detection
Visual leak detection is the recognition of liquid appearing where it should not be - under a tank, beside a pump, on the floor around an installation. The system reacts to a change in the appearance of a surface, not to the chemical composition of a substance.
