Video analytics (also known as Video content analysis, VCA, or Video Motion Detection, VMD) consists in a software that exploits images from a CCTV camera, in order to elaborate an interpretation which characterizes a situation, and allows to warn a user about it. In opposition to image analysis, video analytics is based on the observation of the evolutions of single targets in a scene, while filtering potential perturbating effects, such as camera vibrations, or day/night illumination change, or cloudy vs. sunny changes. It aims at locating and analyzing these changes in order to get an interpretation of it.
Video analytics users are site operators (sensitive sites, or industry, or process, ...) who wish to monitor continuously their installations in order to ensure a permanent and reliable diagnostic of the respect of the rules they have assigned to be monitored, whilst reducing the cost of this monitoring.
Examples of video analytics users, in the case of EVITECH products, are the following :
- sensitive sites, for protection against robbery of goods, or staff, or intellectual property, spy and terrorism. They are official sites, military, nuclear, industries (ex : metal, tools, goods), luxe, transport, logistics...
- toll/customs and police officers, for borders control and inquiries,
- public site operators, in order to detect trouble in public behaviour and displacements. They are museums, sensitive sites with a public space around, often in the cities.
- motorway operators and ports, rivers, to analyze the moves of vehicles or boats,
- cities and public sites operators for parking control, for controlling duration of presence, detecting laid objects, counting, classifying (by real size and/or shape),
- industries, for early fire start detection,
- oil and gas sites, for detection of oil & gas leaks, or controlling flares.
Video analytics users require an acute detection capacity AND simultaneously the lowest false alarms rates.
EVITECH's video analytics solutions are proven for detecting 100% of searched events (single targets) when they are visible "with a naked eye" on the camera image, with (e. g.) less than 0.5 false alarms per day and camera checked and confirmed on all intruder detection applications on sites installed in 2011 with this application (several hundreds of cameras).
