Actual Take Off Time (ATOT) is the time that an aircraft takes off from the runway. ATOT is equivalent to ATC ATD–Actual Time of Departure or ACARS = OFF.

Actual Turn-round Time (ATTT) is the time period between actual in block time and actual off block time (AOBT – AIBT).

Actual Taxi-In Time (AXIT) is the time period between the Actual Landing Time (ALDT) and the Actual In-Block Time (AIBT). AXIT = AIBT - ALDT

Actual Taxi-Out Time (AXOT) is the time period between the Actual Off-Block Time (AOBT) and the Actual Take Off Time (ATOT). AXOT = ATOT - AOBT

Age and Gender Detection in Video Analytics is a function that automatically estimates age and gender of a person from an image, video or video stream.

Analog Security Cameras transmit the video feed via a coaxial cable. A digital video recorder (DVR) converts the analog signal to a digital signal and stores it on the hard drive.

An anchor tenant, also referred to as an anchor store or key tenant, is a significantly larger tenant in a mall, often a department store or chain of retail stores. They are usually found at the ends of shopping malls.

Anomaly detection involves the identification of events, behaviors, or objects that deviate significantly from the norm or expected patterns. In the context of video analytics, it aims to identify abnormal activities captured by security cameras.

An anonymous people counter counts people in real time, without making use of any graphical or video data. This ensures anonymity, and protects the privacy of the detected objects identified as people.

Apron or Ramp is a designated area of an airport where aircraft are parked, unloaded, loaded, refueled, and boarded by passengers. The apron is typically located adjacent to the terminal building.

Average Transaction Value (ATV) refers to the average amount a consumer spends on a single purchase.

An axle counter in the context of road traffic systems is a sensor device used to monitor vehicle traffic on roads and highways.

Business Intelligence (BI) is a process of analyzing data and presenting actionable information that helps executives, managers and employees within organizations to make informed business decisions.

Background Change Detection in Video Analytics is a function which detects the change of background of a video or video stream over time. A background change can be triggered by a change in perspective, constructions or a broken camera.

Bandwidth is the maximum data rate of available information capacity on a physical communication link. Bandwidth is equivalent to the maximum available bitrate and usually measured in megabits per second (Mbps).

A Bicycle Counter is a device installed at roads to measure bicycle traffic. Bicycle Counters can be realized with different technologies such as radar, lidar or security cameras.

Bitrate is the number of bits that are transmitted or processed over time.

The Block Time is the time of a flight measured from the start of movement ("off-block") to the end of movement ("in-block"). It includes taxi-out time, flight-time and tax-in time.

A bullet camera is a security camera with a cylindrical shape.

Bus lane enforcement refers to the measures and systems put in place to regulate and ensure compliance with traffic rules and regulations in bus lanes.

Constant Bitrate (CBR) as opposed to variable bitrate (VBR) keeps the bitrate of a signal during compression constant independent of the signal complexity. As a result the quality of the result can vary.

Communications-Based Train Control (CBTC) is a modern signaling and control system used in rail transportation.

A Command and Control Center is a centralized facility designed to manage and oversee operations within an organization or a system.

A Closed Circuit Television (CCTV) system or video surveillance system comprises of security cameras and monitors (TV). Closed Circuit indicates that the system is restricted to authorized users.

CCTV analytics software is a type of software that uses artificial intelligence and machine learning to analyze video footage from CCTV cameras.
