Title
(EN) SURVEILLANCE SYSTEM
(FR) SYSTÈME DE SURVEILLANCE
Abstract
(EN) A video surveillance system is disclosed. The system includes: at least one camera to observe a surveillance field and provide resulting video data; at least one beacon comprising at least one light emitting element and a controller providing an actuation sequence to the light emitting element such that it emits a binary signal comprising sequential on/off flashes; and a video analytics system comprising a processor configured to receive video data captured by the, at least one camera and analyse the video for the presence of light emissions from a beacon. The binary signal may consist of a plurality of transmission packets, each repeating an encoded set of data. Each transmission packet may comprise a plurality of functional sub packets, for example, a first sub-packet comprising a fixed code and a second sub-packet which changes between transmission packets. The video analytics system processor is configured to identify the sequence corresponding to the first sub-packet to determine a beacon identification and verify the authenticity of the beacon using the second sub-packet. A method of video surveillance monitoring is also disclosed.
(FR) L'invention divulgue un système de vidéosurveillance. Le système comprend : au moins une caméra servant à observer un champ de surveillance et à fournir des données vidéo ainsi obtenues ; au moins une balise comprenant au moins un élément électroluminescent et un dispositif de commande fournissant une séquence d'actionnement à l'élément électroluminescent de sorte qu'il émette un signal binaire comprenant des clignotements séquentiels de allumé/éteint ; et un système d'analyse vidéo comprenant un processeur configuré pour recevoir des données vidéo capturées par ladite caméra et pour analyser la vidéo par rapport à la présence d'émissions de lumière à partir d'une balise. Le signal binaire peut être constitué d'une pluralité de paquets de transmission, chacun répétant un ensemble codé de données. Chaque paquet de transmission peut comprendre une pluralité de sous-paquets fonctionnels, par exemple, un premier sous-paquet comprenant un code fixe et un second sous-paquet qui change entre des paquets de transmission. Le processeur de système d'analyse vidéo est configuré pour identifier la séquence correspondant au premier sous-paquet de façon à déterminer une identification de balise et pour vérifier l'authenticité de la balise à l'aide du second sous-paquet. L'invention divulgue également un procédé de surveillance de vidéosurveillance.
