Definitions

  • the invention relates to a method and a device for notifying a network unit connected to an area monitoring camera via an analog data network in an event to be detected by the surveillance camera.
  • Video surveillance systems usually consist of surveillance cameras connected to storage units for storing the captured video data and / or monitors for displaying the captured video data over a data network.
  • an analog or a digital data network such as, for example, a packet-switching communications network can be used as the data network.
  • the surveillance cameras can also be connected to a processing unit, such as a computer, a server, etc., which can process the video data recorded by the surveillance camera.
  • processing units can detect movements (motion detection), observe objects such as persons, vehicles, doors, windows, parking spaces etc. (tracking) etc.
  • video images or video data usually become analog transferred to then be displayed on video walls with multiple monitors and / or stored analog or digital. It is often left to the viewer to evaluate and interpret the video images. Since images coming from multiple cameras can not all be displayed simultaneously on a video wall, but are displayed sequentially (also in groups), it can easily happen that events can not be displayed or can not be perceived.
  • An intelligent surveillance camera according to the preamble of claim 1, for example, from Panasonic: "Color CCTV Camera WV-NP472 Operating Instructions", 2002, or AXIS Communications AB; "AXIS 221 Network Camera User's Manual Rev.1.0", 2005.
  • Movement is detectable in a predeterminable image area of acquired digital video data.
  • the detected movement activates an alarm output of the surveillance camera.
  • the image data captured by the surveillance camera as well as the alarm can be transmitted via a digital communication network to a correspondingly configured network node, for example to a so-called event server or PC, where image data and alarm information can be displayed in corresponding browser windows.
  • EP 1 081 953 A Furthermore, a device with a digital video camera, an image memory and a digital signal processor (DSP) is known. An image captured by the video camera is superimposed by the DSP on a text in the image and stored in the image memory and passed on in digital form.
  • DSP digital signal processor
  • the object of the present invention is to provide a possible simple and efficient way to notify a network unit in an event detected by a surveillance camera event.
  • a core of the invention is to be seen in that the video data recorded by a digital surveillance camera are at least partially evaluated with regard to events to be detected in the surveillance camera.
  • a positive evaluation result that is to say when an event to be detected is detected, at least one reference date is added to the video data and transmitted to a network unit via an analogue data network.
  • An event to be detected may be, for example, a movement in the monitored area, a fire, a smoke, stationary vehicles, moving vehicles (slow-moving, wrong-moving (in the opposite direction, ghost driver) etc.), monitoring of niches (tunnel niches ), a manipulation on the surveillance camera, such as covering the camera, opening the housing, twisting (changing the visible or monitored area) of the camera, an object to be monitored, such as a car, a door, a window , an entrance lock, a parking lot, a building, a staircase etc., a person to be monitored, etc. act.
  • Even so-called continuous events such as the continuous coloring of a surface or the event-dependent coloring of such a line, surface etc. in a video image are considered as events.
  • a reference date can be an alphanumeric message that is superimposed during playback of the video data, that is overlaid with the video data.
  • an audible and / or graphical reference date are conceivable.
  • a line, an area etc. in a specific color could be displayed as a graphical reference for the video data.
  • diagrams and the fading in of a certain geometry in the evaluated video data are conceivable according to the invention.
  • the video data can also be transmitted via a packet-switched communications network such as, for example, an IP communications network, a mobile communications network, etc. This can be done parallel to the analog transmission of the video data including the at least one reference date.
  • the at least partial evaluation of the video data is carried out according to the invention by a processing unit such as a processor unit (DSP), a host processor etc. in the surveillance camera.
  • a processing unit such as a processor unit (DSP), a host processor etc. in the surveillance camera.
  • the digital video data with the at least one reference date is converted into analog signals and transmitted to the network unit via an analogue data network.
  • the evaluated video data are encoded and / or buffered in a memory unit of the surveillance camera.
  • the stored encoded video data is then decoded again by means of a decoding unit.
  • a network unit an image output device, a monitor, a television, a video projector, a mobile image output device, a video data processing device (computer, server, etc.), a network storage device, etc.
  • the evaluation of the digitally recorded video data can be performed automatically by the camera depending on events, lighting conditions, environmental influences, etc. In this case, a false color display for highlighting certain features, a superimposition of stored video data, an increase in contrast of the video data, etc., can be carried out for the evaluation.
  • the evaluation of the digitally recorded video data is triggered due to manually entered commands or additional information.
  • Such commands or additional information can be transmitted from a computer, a server, a database, etc. via, for example, a packet-switched communication network to the surveillance camera.

  • the processing unit VE of the surveillance camera SC can execute various image processing algorithms or evaluation methodologies.
  • the algorithms required for the evaluation can be downloaded via, for example, the packet-switching communication network. This simplifies the maintenance and the updating of the surveillance camera according to the invention. For example, sabotage detection or manipulation detection can detect that the surveillance camera SC has been twisted, covered, darkened, etc. A corresponding warning message or a note date can then be superimposed on the image superimposed on the recorded image (see FIG. 3 ).
  • the analog video data is transmitted and displayed via the existing monitoring system by means of a transmission unit SE. By displaying the notice date, a viewer can take appropriate action. It is also conceivable for surveillance camera SC according to the invention to process the recorded video data as a function of events to be detected, light conditions or other environmental influences (eg by highlighting false colors to highlight certain features, overlaying stored images, increasing contrast, etc.). This video data processing can be done without additional external control. However, it is also conceivable that additional information or commands are transmitted to the camera via one of the connections, eg Ethernet (packet-switching communication network).
