Definitions

  • the invention relates to a video monitoring device with at least one image recording device and a recording device for the recorded image signals.
  • Such video monitoring devices are used, for example, for monitoring bank or post rooms or counters.
  • the recording device is put into operation by being triggered for the recording process with the aid of a push button or switch.
  • statistical studies show that it can be relatively difficult, particularly when monitoring bank or post rooms or counters, to carry out the simple movement for triggering by means of the push button or switch for security reasons or for psychological reasons.
  • monitoring large spaces where one or a few monitors are located it can be difficult to capture the right pictures at the right time.
  • the known systems when monitoring - to replace staff, only of limited use.
  • the invention has for its object to provide a video surveillance device of the type mentioned, with the help of simple means a constant monitoring of objects and processes is possible and the recorded information is reproducible, the decision to reproduce the information still after surveillance can be taken.
  • the video monitoring device uses simple means to store the chronological sequence of the images recorded by the image recording device.
  • the images are stored on the tape of the audio frequency / tape recorder for a certain time and then deleted, so that the tape is available for further recordings. If a certain process is to be recorded by the video monitoring device, it is switched off after it has expired. The information recorded before the shutdown was saved. The stored information can now be evaluated in detail.
  • monitoring device If the monitoring device is not interrupted, information on the tape is deleted after a certain time. The tape is released to record new information. In this way, continuous monitoring is possible when inserting tapes of finite length. It is also possible to reproduce certain processes that only show at the end of their process that their reproduction is advantageous.
  • Audio frequency tape recorders are readily available on the market so that the cost of the video monitor is within normal limits.
  • the information can be saved for 60, 90 and 120 minutes.
  • Audio frequency recorders usually operate at low tape speeds, so that the tape has a long life. Although this limits the data storage density, it is sufficient for a recognizable reproduction of the recorded images. Storage densities of 6 to 60 fields per minute can be achieved, which are then reproduced at a slower speed with the aid of the tape recorder.
  • a further recording device which is started when the tape recording device which stores the previous information is stopped in order to store further information from one of the image recording devices.
  • relatively short tape lengths in the tape recorder can be used.
  • the output signals of the image pickup devices 1 to 4 then become an image frequency / audio frequency converter 5 fed.
  • the audio frequency signals formed in the converter are transmitted to an audio frequency tape recorder 6 and stored there.
  • the tape storage device stores over 60, 90 or 120 minutes or one or more hours of recording, while the information in front of it is deleted again.
  • the storage time can be set with the help of a part-time code generator 7.
  • an audio frequency / image frequency converter 8 and from there to a screen 9.
  • a memory can also be connected to the audio frequency / image frequency converter 8, into which the audio frequency signals can be input for a further reproduction as often as desired.
  • the screen 9 can also be connected directly to the image recording devices 1 to 4, so that the recorded processes can also be made directly visible.
  • the image recording devices 1 to 4 With the image recording devices 1 to 4, three, four or six images per minute can be recorded. At least 50 images are required to identify an event and to evaluate it.
  • Another advantage of the device is that the audio frequency signals can be transmitted over simple distances with simple lines, so that image frequency lines only have to be provided between the image recording device and the image frequency / audio frequency converter.
