Video Content Analysis: how far along are we now?<\/h1>\n

Alert operators.
\nAn extra pair of eyes.
\nFewer monitors in your control room.
\nIt is possible if you have expanded your camera system with Video Content Analysis (VCA).
\nVCA analyses your camera images (in real-time), recognises certain situations and, if necessary, generates alarms.
\nIn the event of an alarm, the operator is offered specific images showing the deviation.
\nIf you combine VCA with other forms of detection, even more reliable detection is possible, so that hardly any false alarms occur. <\/strong> Video Content Analysis is no longer new.
\nThe first serious systems emerged about 10 to 15 years ago.
\nIn the meantime, the technology has improved considerably, especially in terms of reliability.
\nDevelopments in camera technology have also played an important role in this.
\nVCA detects moving objects and then determines the size of an object and its length\/width ratio.
\nBased on this information, it can be determined to which ‘object class’ (e.g. human, animal, vehicle) the object belongs.
\nVCA also determines the direction in which and the speed at which the object moves.
\nThe color of the object can also be determined.
\nIf certain criteria are met, the system generates an alarm.
\nFor example, a virtual line or a surface can be ‘made’ directly on the inside of the fence in the outdoor area.
\nCameras with VCA can then detect all objects (or only the objects in a certain object class) that cross that line or come within the plane.
\nBut it is also possible to determine that a machine stops because there is no more movement, or that a car stops in a place where it is not allowed.
\nVCA is also used for crowd management: counting the number of people in a certain area, on the basis of which certain decisions can be made.
\nThis is already happening \u2013 albeit in test setups \u2013 at the Nijmegen Four Days Marches and during the Olympic Games.
\nVCA can also be used to detect manipulation, such as rotating or covering a camera.
\nAfter all, any deviation from the set standard is detected.
\nMost VCA systems can detect the following: <\/p>\n
