  • a virtual fence can be made which allow to track any ship in a harbor visually.
  • the flexibility of the system, especially MSMUR 109 allows to allocate resources flexibly, e.g. allowing to continuously follow a particular ship. No cabling is necessary to set up the complete port security system.
  • the flexible surveillance network system 101 comprises a traffic surveillance system which comprises a plurality of remote units 201 being arranged along a highway with, in normal circumstances, driving vehicles.
  • a first remote unit 201 at a first location and a second remote unit 201 at a second location along the highway each comprise a surveillance camera 202 and a microprocessor 203 connected to the surveillance camera 202, the microprocessor 203 being arranged to retrieve an image of each vehicle that is driving on the highway section captured by the surveillance camera 202.
  • the microprocessor 203 is further arranged for retrieving the license plate of each vehicle from the image of that vehicle, attributing a timestamp to the license plate of each vehicle, the timestamp associated with a time at which each vehicle passed the location of the remote unit 201, and storing the license plate number and the attributed timestamp in the storage memory 204 of the remote unit 201.
  • the surveillance central controller system 101 is arranged for retrieving the license plate number and the first and the second timestamp attributed to the license plate number from the first and second remote units 201.
  • the surveillance central controller system 101 is further arranged for dividing a distance between the first and the second location by the time difference between the first and the second timestamp and comparing the result to a predefined value, i.e.
  • the surveillance central controller system 101 is further arranged to calculate a fine and provide the license plate number to an administrative center, which is arranged to send a traffic violation ticket to the registered owner of the car which measured velocity exceeded the maximum speed, fully automated and without any human interference.
  • at least one of the remote units 201 is located at an intersection and video data from the intersection is stored for a predefined amount of time. This enables the operator of the flexible surveillance central controller system 101 to review an event that previously occurred on, or in the vicinity of, the intersection and determined, for example, the cause of an accident that happened at that intersection.
  • the surveillance central controller network 101 comprises surveillance cameras 202.
  • the surveillance cameras 202 comprise a microprocessor 203 being arranged for receiving the captured video and/or audio data from the surveillance camera 202 and for recognizing the type of each vehicle of the plurality of vehicles on the highway (i.e. whether they are cars, cars with trailers, earth moving equipment, heavy trucks, tanks etc.).
  • the flexible surveillance central controller system 101 is further arranged to increase the duration of consecutive (with respect to distance) green lights for the heavy traffic (i.e. heavy trucks, cranes, earth moving equipment etc.) which typically needs a long time to accelerate, if compared to luxury sedans, and hence improve the circulation of the total traffic because the heavy traffic is not forced to stop frequently.
  • camera's 202 may be provided to check dangerous situations on one or more traffic lanes, e.g. in case of an accident. When detecting such a situation, an alert may be generated, and manually or automatically, the respective traffic lane may be blocked off by visual markings. Also, the video data stream may be used by an operator to assess the level of an accident, and e.g. whether emergency services such as ambulances are needed and how many.

Abstract

L'invention concerne un système réseau de surveillance comprenant un système de contrôle et de commande central (101), une ou plusieurs sources (201) de données fournissant des données vidéo, et une liaison (103, 104) de communication entre la ou les sources de données, p. ex. une liaison de communication sans fil. La ou les sources (201) de données comprennent des moyens (203) de traitement permettant des traitements des données vidéo tels que le traitement des images, la détection d'événements, la compression des données, le stockage de données, et le système (109) de commande est conçu pour commander la ou les sources (201) de données, et les flux de données provenant de la source ou des sources de données.
