Group Detection in Video Analytics is a function that automatically recognizes groups of people in a video or video stream.

Gun Detection is a technology that utilizes AI video analytics and machine learning to automatically identify the presence of firearms within a video feed.

H.264 is a video compression standard.

H.265 is a video compression standard and the successor of H.264.

Halons are known to be the most effective fire extinguishers in the aviation industry. They are gaseous when discharged, non-conductors of electricity and extinguish fires by disrupting the chemical reaction causing them.

Hard hat detection refers to the use of technology, often computer vision and artificial intelligence (AI), to identify whether individuals in a specific setting are wearing safety hard hats or helmets as required for safety reasons.

HD or 720p is an image resolution of 1280×720 pixel. HD is roughly equivalent to 1 MP.

Headway is the time that elapses between the arrival of the leading vehicle and the following vehicle at the designated test point.

A heatmap in video analytics is an overlay over the camera image to display frequently visited areas or areas of high activity.

Holdover Time (HOT) is the period of time for which ice and snow is prevented from adhering to the surface of an aircraft, i.e. the length of time between application and take-off.

Hard shoulder running (HSR) enables dynamic use of hard shoulders as an extra driving lane with the aim to increase road capacity in times of high traffic demand.

Identity and Access Management (IAM) is the process defining access control and authorized users through policies.

IBIS-IP is an abbreviation of Integrated On-Board Information System (IBIS) based on the Internet Protocol (IP). The IBIS-IP standard is defined by the Association of German Transport Companies (VDV) in the publication VDV 301.

IBIS is an abbreviation of Integrated On-Board Information System (IBIS). The IBIS standard is defined by the Association of German Transport Companies (VDV) in the publication VDV 300.

In-Block Time is the time at which an airplane arrives at the parking position after landing and taxi is completed.

Devices and security cameras with an IK10 rating can withstand an impact with an impact energy of 20 joule which is equivalent to an impact of a 1 kg mass dropped from 2 meters height.

The IK Code is an international standard which describes the degree of protection of a housing against mechanical impact.

Image resolution refers to the number of pixels captured in an image or video frame. The more pixels there are, the higher the resolution of the image/video and the more detail can be seen. Common image resolutions are HD, Full HD, WQHD and UHD / 4K.

Incident management refers to the structured approach and set of processes employed to handle and resolve incidents efficiently and effectively.

An Inductive Loop Traffic Detector detects vehicle presence through induction. The inductive loop consist of coiled wires which are installed in the road and a logic unit. Vehicles passing the loop can be detected through a loop field change.

Intersection monitoring refers to the systematic control of vehicle and pedestrian movements at road intersections to enhance safety and efficiency.

Intrusion detection system (IDS) in physical security refers to a security mechanism to detect unauthorized entry into a protected area or facility. It works by monitoring the environment for signs of intrusion, such as motion, heat, or sound.

Intrusion Detection Systems (IDS), also referred to as Intruder Detection Systems, are sophisticated security solutions designed to detect and alert individuals or security personnel about unauthorized access or breaches in physical premises. 

Input/Output (I/O, also referred to as IO) is the communication between an information processing system, such as a computer, and the outside world, such as peripherals, actuators or sensors.
