Definitions

  • the invention relates to a system for remote monitoring of rooms with at least two remote image devices that are connected to a dial-up network.
  • Remote image devices are to be understood here as receiving or transmitting devices which either have only one video camera or only one screen or both. In the latter case it is - if audio signals are also transmitted - video telephones.
  • Room surveillance systems in which video telephones connected to a dial-up network are used are known.
  • DE-A1-3827928 describes a video telephone that is suitable for room monitoring in conjunction with some additional circuits.
  • These additional circuits include an image memory, with the aid of which the differences between successive images of the running camera of the video telephone set are checked. If the difference exceeds a predetermined level, an alarm signal is automatically issued.
  • a monitoring station can also be called automatically in parallel via the dial-up network.
  • the invention has for its object to provide a room surveillance system of the type mentioned, in which a scene analysis is omitted to detect a dangerous situation.
  • One embodiment consists of the fact that at least one remote image device contains means which are intended to convert received character combinations into control pulses for the Implement the change in the position of his camera.
  • the invention will now be explained in more detail with reference to the figure and an exemplary embodiment.
  • the figure shows schematically an intercom that is suitable for a system according to the invention.
  • the video telephone 1 shown in the figure is divided into two groups 2 and 3 of functional units.
  • the functional unit 2 contains, as sub-units, all units which are required for a video telephone device according to the prior art, namely a camera 4, a monitor 5, a control unit 6 and a transmitting and receiving part 7.
  • the operating devices for the video telephone device 1 are not entered , since such devices are of secondary importance for the invention.
  • all functional units are summarized which are still important, among other things, for the special design of the video telephone, such as a data-reducing encoder, a corresponding decoder and a network access device for both transmission directions.
  • Group 3 of functional units is activated together with control unit 6 when the video telephone set is to be used for remote monitoring.
  • Group 3 consists of two memories 8 and 10, a comparator 9 and a timer 11.
  • the dial-up network itself is an ISDN network in which, for example, the caller's number is transferred to the called party when a call is made. This fact - as will be explained in more detail below - is used for a check by the called subscriber.
  • the video telephone 1 is switched to a "ready to test” state via the control panel (not shown). If it receives a call in this state, it changes to an “input” state, which begins with the setting of a timer 11 and ends when it expires. In the "input” state, the caller's number transmitted via the ISDN network is read into the memory 8. Separately, a further combination of numbers, which the caller has to enter on his device after the call number, is also stored in the memory 8. This combination of numbers is called the input number here. The input and telephone numbers are used to check whether the caller is authorized to access or not.
  • the test is carried out by the comparator 9, to which the two numbers are fed one after the other and which compares them with the numbers read by the controller 6 from the second memory 10. If one of the numbers received does not match the stored numbers, the video telephone 1 is reset to the "ready to test” state and the connection is released. Otherwise, the video telephone set 1 is put into a "send” state in which it transmits the images recorded by the camera 5 to the caller.
  • the caller can also enter character combinations via his operating device, which are transmitted by the controller 6 as pulses to the camera 5 for changing their position. If the connection is triggered by the caller, the video telephone device 1 falls back into the "ready to test” state.
  • z. B the input and output of data from the functional units of group 3 controlled by the control unit 6.
