Definitions

  • This invention pertains to a system and method for establishing and maintaining a central repository archive of digital video images or signals transmitted from a variety of sources via the Internet, direct transmission or any other means using telephone lines, cable networks, satellites or microwave transmitters.
  • Digital video cameras are used to capture the images to be stored.
  • Preferably separate sections of the depository are dedicated for different users. A user can only retrieve digital imaging data from his own section, thus providing security to the system.
  • Video cameras are commonly used to perform a large number of functions. Many of these functions pertain to security concerns. For example, many establishments associated with retail sales and similar activities involving cash transactions use video cameras to monitor and record the presence and movements of customers. Therefore if a robbery occurs, information is readily available about the perpetrators. Another frequent use for video cameras is the monitoring of the activities of employees to insure that they perform their job properly and do not misappropriate money and/or goods.
  • video cameras are used to monitor premises where attendants are not present or are present only at predetermined intervals. Arrangements of this type are found in museums, perimeters of warehouses, prisons, factories and even private homes.
  • Some facilities use tapes arranged in loops to record images only for a predetermined time period, for example, twenty four hours.
  • This arrangement has the same disadvantages as the system wherein tapes are re-used and moreover, the endless tapes usually break fairly often and must be spliced or discarded.
  • the existing systems become even more complex in facilities in which multiple cameras are used since frequently individual tapes are used for each camera, and each of these tapes must be separately replaced, tagged and inventoried.
  • a further disadvantage of the present systems is that they require the purchase and servicing of expensive equipment which often becomes rapidly obsolete. Moreover, all the systems require personnel with special training
  • an objective of the present invention to provide an archiving system in which images from a plurality of cameras located at various facilities and/or customers, are transmitted to a single central location where they are indexed, date/time stamped and digitally archieved in accordance to instructions from each user.
  • a further objective is to provide a system wherein a central archiving system is maintained in which images from different users are stored in separate folders to insure their security.
  • a further objective is to provide a centralized video archiving system which frees small business from the necessity of buying their own equipment, maintaining the equipment, training personnel to operate the equipment, storing the recorded tapes and so on.
  • An objective of the present invention is to provide a system which allows a user to see an image from a remote video camera instantaneously using standard computer equipment.
  • a further objective is to provide a security system that can provide instant imaging using relatively inexpensive equipment.
  • a further objective is to provide a security surveillance system which is easy to use.

  • the central station further includes a data bank which might comprise several hard drives or other mass data storage media.
  • the images are transmitted by using standard data channels, standard telephone lines, on the Internet and other similar means.
  • each camera is provided with a unique identification code which code is transmitted together with the images.
  • Camera codes and user codes are used by the central station to store the data to specific partitions or folder designated for the respective users.
  • the images are then stored as data in accordance with parameters set by users. Variances from programmed conditions or other factors determined by user can trigger user or third party (i.e., security detail) notification.
  • the system also includes monitors disposed either at the users' facilities or off the premises. The users can then access and view either the images being currently sent to the central station or images which have been stored in the data bank.
  • the system may also be used in environments wherein current and archieved images are used to detect changes in the characters of various objects or other items.
  • the user can request and receive current video signals on a PC or other similar device through an Internet, Intranet or other distributed computer network.

  • the images instead of storing the images in a databank dedicated to the lending institution, the images may be stored in an open databank available to a pool of lending institutions. Once the images are thus stored, they can be accessed, i.e., retrieved by any of the lending institutions, or other institutions, such as insurance companies, at will.
  • archiving and surveillance systems have been described in conjunction with an industrial or commercial environment.
  • the subject invention may be used in museums, exhibit galleries and similar environments.
  • museums can reduce costs by managing their surveillance more efficiently.
  • Critical sections and rooms of the museum may be equipped with digital video cameras and the images thus collected can be archived as discussed above. If an intrusion or vandalism takes place, the images stored from individual cameras or rooms can then be easily retrieved by time and date and reviewed by the management of the museum and/or the appropriate authorities.
  • Hospitals can benefit from the present system by monitoring patient care more effectively thereby reducing insurance costs. Doctors can monitor certain patients or procedures from home or office. Recordings from various sites within the hospital can be used as a teaching, training and evaluation tool. Homeowners could use the present system thereby gaining access to sophisticated surveillance techniques without the normal associated high costs of acquiring, and maintaining the same.
  • Cooperative apartment dwellers and rental apartment dwellers would be able to "piggy back" their surveillance on the "ground floor” system. If the building would protect the main door and service door, the same T-1 would be able to handle each elevator vestibule with no additional communication cost. This should substantially eliminate “inside jobs” and if properly publicized, should deter “would be” thieves.
  • Cameras could be set up on an "as needed" basis in order to monitor a construction site, monitor a suspect during a trial period etc., without creating the infrastructure each time.

Abstract

L'invention concerne un système et un procédé permettant d'archiver des signaux à partir d'une pluralité de caméras vidéo (14) au niveau de différents sites, qui consiste à émettre des signaux (18) vers une station centrale (16), et à les stocker dans une banque de données (26) dotée de sections attribuées à chacun des utilisateurs ou des sites d'une pluralité. Les signaux stockés sont horodatés, et également identifiés par le site d'origine et une caméra, de sorte qu'il est facilement possible de les trouver et de les extraire en fonction de l'heure et de l'emplacement de l'enregistrement. Un identificateur unique est attribué à un utilisateur qui l'utilise pour extraire les signaux de manière sûre. Il est possible de s'assurer qu'un utilisateur ne peut accéder aux signaux d'un autre utilisateur et les extraire. Les signaux vidéo sont affichés sur un écran, de manière sélective, soit avant leur stockage, soit après leur extraction. Des moniteurs (32) permettant de visualiser les signaux peuvent être placés soit au niveau des sites où les caméras sont implantées, soit au niveau d'un site à distance. En outre, un PC séparé au niveau du site peut être couplé à l'une des caméras vidéo, et agencé de façon à recevoir des images courantes, soit directement, soit par l'intermédiaire de la station centrale de sorte que l'utilisateur peut voir les images courantes à partir desdits moniteurs.
