Train Detection in Video Analytics is a function which detects trains in images, videos or video streams. Through the continuous detection and tracking of a train throughout a video, the train's speed and distance can be obtained.

A Train Detection System detects if a certain track is currently occupied by a train and provides that information to the train control system.

Trespassing, the act of entering or remaining on someone's property without permission, poses a significant challenge to property owners and the general public alike.

Turnaround control refers to the process required to prepare an aircraft for its next flight after it has landed.

The User Datagram Protocol (UDP) is an IP network protocol which does not require prior communication to set up communication channels or data paths between different hosts.

Ultra-HD (UHD) is an image resolution of 3840 × 2160 pixel. UHD is roughly equivalent with 8 MP.

Unattended Object Detection is a Video Analytics function which detects from a video or video stream if objects such as luggage are left unattended.

Unauthorized Access Detection is crucial for protecting sensitive information from unauthorized access. It includes strategies like IDS, IPS, UEBA, access control, and SIEM to promptly identify and respond to unauthorized access attempts.

Uncoordinated Fixed Time Signals are observed in rural areas that do not have traffic signals in close proximity and thereby do not require coordination. The signal timings in these signals are pre-timed to suit the existing traffic demand.

Uncoordinated Traffic Actuated Signals have in-pavement loop detectors installed to detect the minor street traffic and thereby activate the minor street signal timing.

Unicast Video Streaming is a technology to stream a video from one camera to one clients over an IP network via Transmission Control Protocol (TCP).

Vehicle-to-everything (V2X) is communication between a vehicle and any entity that may affect, or may be affected by, the vehicle.

Variable Bitrate (VBR) as opposed to constant bitrate (CBR) varies the bitrate of a signal during compression depending on the complexity of the underlying signal aiming for constant quality.

Video Content Analytics (VCA), also known as video content analysis, video analytics or video analysis, describes the process of analyzing video material automatically for a certain purpose.

A Visual Docking Guidance System is a system used to assist aircraft to dock at the exact position in front of respective gates.

VDV 457 is a guidance for the usage of Automatic Passenger Counting Systems in public transport.

A Video Management System (VMS) connects to security cameras and stores the video stream. Video Management Systems provide a user interface to view and playback video streams.

Variable Message Signs (VMS) are electronic roadside signs used to post traveler information messages to inform drivers of incidents, travel times, detours, special events, and other useful road conditions or travel information.

Vulnerable Road Users (VRU) is an umbrella term used to refer to a section of road users who are more susceptible to accidents and injuries on the road than the average road user.

Variable Speed Limits (VSL) is an active traffic management (ATM) strategy that uses dynamic speed limit signs to slow traffic before and through adverse conditions on the freeway to improve safety and keep traffic moving efficiently.

A video surveillance system (VSS) is a system that uses video security cameras to monitor and record activity in a specific area.

Video Surveillance as a Service (VSaaS) is a cloud-based video surveillance solution that enables security operators to remotely monitor multiple premises using cameras which send video to a central cloud storage over the internet.

Vehicle Classification distinguishes vehicles by type such as car or truck based on features like number of axles. Vehicle classifications vary by country. We explain the differences between FHWA, COBA and TLS 8+1 vehicle classification.

A vehicle traffic counter is a device or system used to monitor and record the number and types of vehicles passing a specific point on a road or highway.

Video Analytics (VA) uses computer algorithms and artificial intelligence to analyze video content for a specific purpose. We can also call it as a video content analytics or video analysis.
