Definitions

  • the invention relates to a device for monitoring processes outside the field of view of a surveillance person according to the preamble of patent claim 1.
  • the monitoring cameras are generally connected to one or more screens.
  • the camera either continuously delivers images that are monitored by the surveillance personnel on the screen or images are stored at intervals, which results in a type of time-lapse recording (“time lapse recording”) that can be saved and viewed if necessary.
  • the image signals sent by the cameras are usually switched by the person monitoring to the individual screens assigned to the cameras.
  • Such monitoring systems are also used in the private sector for monitoring house and apartment doors or garage entrances or the like.
  • the disadvantage here is that an additional screen must be set up in the apartment on which the images supplied by the camera can be displayed.
  • Another disadvantage is that many operations are necessary for monitoring. So the camera and the screen must be switched on and after the surveillance person has seen the images delivered by the camera to the screen, all devices must be switched off again. For monitoring purposes, the person supervising must interrupt their activities.
  • the device according to the invention offers many advantages.
  • An additional screen next to the TV screen is not necessary. This can save the cost of a screen.
  • the use of a television set opens up the possibility of a picture of the area to be monitored being briefly faded in while the person watching a television program, the surveillance camera being able to be switched on by means of a switch-on device. In this way, the area to be monitored can be monitored "by the way", so to speak.
  • the image signals can be transmitted to a receiving device connected or integrated with the television, the status of the television being changeable by the receiving device so that the images of the surveillance camera are on the screen appear or appear in a screen window. After the images from the surveillance camera have been shown for a predetermined time, the old status of the television set can be restored.
  • the switched-off television set can be switched on automatically by the receiving device, for example if the surveillance camera has been switched on by means of the switch-on device by processes from the area to be monitored. After a predetermined time, the surveillance camera and the television set can be switched off again. The supervising person can pursue employment and still does not have to do without surveillance. By automatically switching on the television, you are made aware of the area to be monitored.
  • the wiring effort is considerably reduced and the surveillance camera can be installed more flexibly. This is particularly advantageous if the device for monitoring people in need of care is to be used, for example, in a retirement home or a hospital, since the surveillance camera can then be installed quickly and easily in a specific room if necessary and can also be removed after the surveillance is no longer necessary can.
  • the transmission power must be kept low. The power requirement of the sending components of the device is accordingly low.
  • An embodiment representing a self-contained invention is the subject of claim 3.
  • the conversion of Switch-on pulse in an infrared switch-on signal via a signal converter makes it possible to minimize the current consumption of the surveillance camera in standby mode, so that the surveillance camera can be switched on and operated in an economically sensible manner with minimal electricity consumption.
  • This configuration also opens up the possibility of operating devices which can be operated with infrared signals, such as, for example, almost all electrical devices in the entertainment industry and many electrical appliances in the household, with signals which are not in the infrared region of the spectrum and thus have a greater range .
  • the infrared switch-on signal sent by the signal converter to the surveillance camera can advantageously be emitted omnidirectionally. This allows the surveillance camera to be moved locally without having to move the signal converter of the device.
  • the switch-on pulse is advantageously in the MHz range.
  • walls or the like can be located between the transmitter and the receiver.
  • the signal converter and thus the surveillance camera can be set up anywhere outside or inside a building, regardless of the position of the transmitter of the switch-on pulse.
  • the switch-on device can be activated according to claim 6 by a remote control device assigned to the television set. This is advantageous because the remote control device is usually within reach.
  • the surveillance camera works independently of the mains, it can be installed easily and very flexibly. This makes it possible, for example in a department store, to change the position of the surveillance camera frequently, which ensures better protection against potential department store thieves is because the thief can no longer know the monitored and unmonitored areas. Even when using the device in the private area, it is particularly advantageous to use a surveillance camera that is independent of the power supply system, since it can be attached at any point, such as a house and apartment door, garden door, garage entrance or the like.
  • the surveillance camera So that the status of the television set can automatically be switched to receiving and displaying the image signals sent by the surveillance camera after the surveillance camera is switched on, the surveillance camera sends a control signal to the receiving device before the transmission of the image signals.
  • control signal is coded according to claim 10, crosstalk from one monitoring device to an adjacent monitoring device whose transmission ranges overlap is not possible.
  • the coding of the control signal can advantageously be set by the user of the device.
  • the connected devices take over the coding.
  • the video transmission of the surveillance camera is thus secured against any unauthorized use.
  • the receiving device has a separation circuit for separating the control and image signals sent by the camera.
  • the receiving device or a part of it is integrated into the television set, so that no additional device has to be set up.
  • a video recorder can be activated by the receiving device in order to record the signals sent by the surveillance camera. This means that monitoring is also possible without monitoring personnel possible. If, for example, the surveillance camera is switched on by a motion detector or the like in the area to be monitored at night, the transmitted image signals can be recorded and can be viewed by the person monitoring the next day.
  • the device for monitoring shown in FIG. 1 has a television set 10, a remote control unit 12 for operating the television set 10 and activation of a switch-on device 14 with which a monitoring camera 16 can be switched on. Furthermore, the device for monitoring has a receiving device 18, which forwards the image signals sent by the surveillance camera 16 to the television 10 for display on a screen 20 of the television 10.
  • the television set 10 has a SCART connection 22 and an infrared receiver 24 in a known manner and can be connected to a power supply at 25.
  • the remote control device 12 contains a remote control 26, as is known from known television sets. With the remote control 26, the television set 10 can be operated via infrared signals, which are to be shown with arrows 28 in FIG. Furthermore, the remote control device 12 contains one Radio frequency transmitter 32, which is part of the switch-on device 14. After activation, for example by pressing a button on the remote control device 12 connected to the radio frequency transmitter, the radio frequency transmitter 32 can generate a switch-on pulse, preferably an amplitude-modulated signal in the MHz range, in particular a signal of the frequency 433.92 MHz, which is shown in FIG. 1 by arrows 34 is send. The remote control device 12 is powered by a battery or accumulator 36.
  • the switch-on device 14 has a signal converter 37.
  • the signal converter 37 contains a radio frequency receiver 38 which receives the switch-on pulse 34.
  • the radio frequency receiver 38 is connected to an infrared transmitter 42 which, after receiving the switch-on pulse by the radio frequency receiver 38, emits a switch-on signal, preferably an infrared signal of wavelength 914 nm, preferably omnidirectionally.
  • the switch-on signal emitted by the infrared transmitter 42 of the signal converter 37 is indicated by arrows 44 in FIG. 1.
  • the switch-on signal preferably has a tone modulation of 30 kHz and a transmission time of 50 msec.
  • the signal converter 37 is preferably supplied via the household electricity network at 45.
  • the surveillance camera 16 has an infrared receiver 46 which receives the infrared switch-on signal 44. Furthermore, the surveillance camera 16 contains a control unit 52 connected to the infrared receiver 46, which in turn is connected to a camera 54, preferably a CCD camera, which detects the area to be monitored. The camera 54 and the control unit 52 are connected to a transmitter 56. After switching on the surveillance camera 16, the transmitter 56 of the surveillance camera 16 sends control signals supplied by the control unit 52 and image signals supplied by the camera 54 via a flat monopole antenna (not shown) at a transmission power of approximately 15 mW. The at 58 control and image signals are preferably transmitted in a frequency range of approximately 2.4 to 2.486 GHz and are preferably frequency-modulated at approximately 16 MHz.
  • the surveillance camera 16 is operated with batteries or accumulators 60. If the operating voltage drops below an adjustable threshold, the control unit 52 sends a signal to the receiving unit 18 via the transmitter 56, as a result of which a warning appears on the screen 20 with an instruction to change the battery 60 of the surveillance camera.
  • the signal converter is not necessary and the radio frequency receiver 38 can then be integrated directly into the surveillance camera 16 instead of the infrared receiver 46.
  • the receiving device 18 has an antenna 62, a converter 64, a tuner 66 and an isolating circuit 68.
  • the antenna 62 preferably operates in a frequency range of approximately 2.3 to 2.6 GHz and receives the signals 58 sent by the surveillance camera 16.
  • the antenna 62 is connected to the converter 64 ("low noise converter"), which receives the received signals transformed to about 2.03 GHz.
  • the converter 64 is further connected to the tuner 66, which in turn is connected to the isolating circuit 68, which separates the control and image signals sent by the surveillance camera 16 and feeds them to the SCART connection of the television 10 via separate lines 72 and 74.
  • the receiving device 18 can be integrated into the television set 10.
  • the tuner 66 and the isolating circuit 68 are preferably integrated in the television set, so that the antenna 62 can also be set up at some distance from the television set, so that a flexible arrangement which is adapted to the spatial conditions can take place.
  • the monitoring device shown in FIG. 2 will be explained as an example.
  • a monitoring person 80 sits in front of the television set 10. Then a person 81 reports in front of the front door 82, for example by pressing a bell button.
  • a switch-on pulse 34 is sent to the signal converter 37, which switches the switch-on pulse into an infrared - Turn-on signal 44 converts.
  • the signal converter 37 is plugged into a socket near the surveillance camera 16.
  • the infrared switch-on signal 44 is received by the surveillance camera 16, whereupon the surveillance camera 16 sends out a control signal 58.
  • the control signal 58 is received by the antenna 62 of the receiving device and forwarded to the television set 10, whereby the television set 10 is switched over to reception and display of the image signals 58 then sent by the surveillance camera 16.
  • the surveillance person 80 thus receives an image of the one to be monitored Area in front of the front door 82 faded in on the television 10.
  • the image signals 58 are preferably superimposed on the screen of the television set 10 for a predetermined time, for example 10 seconds, the images of the area to be monitored being able to be displayed on the entire screen or only in one screen window.
  • radio frequency transmitters 32 which transmit the switch-on pulse 34 can also be provided outside the remote control device 12.
  • the switch-on pulse 34 can be triggered by smoke detectors, motion detectors, noise-sensitive switches, vibrating contacts, actuating the doorknob or other switches, such as doorbells.
  • the surveillance camera can thus be switched on by processes from the area to be monitored. The supervising person an image of the area to be monitored is then automatically displayed on the television.
  • the monitoring device can also be used, for example, to monitor a baby.
  • further functions such as opening the front door or the like, can be carried out via the radio frequency transmitter 32 and possibly the signal converter 37.
  • the control signal sent by the surveillance camera 16 to the receiving unit 18 is preferably coded. This prevents crosstalk from one surveillance system to a neighboring one whose transmission ranges overlap.
  • the code is preferably adjustable by the user of the device.
  • not only image signals but also audio signals from the area to be monitored can be transmitted to the television set with the surveillance camera. This enables visual and audiophone monitoring.
  • the monitoring device can have a plurality of monitoring cameras which can be switched on by different switch-on pulses.
  • the television then shows the image signals sent by the surveillance camera that is switched on.
  • the switch-on device automatically switches on the individual surveillance cameras one after the other, so that the transmitted images of the individual surveillance cameras are successively displayed on the screen.
  • the area viewed by the surveillance cameras is monitored in this way in the so-called scanning mode.
  • Additional screens can also be used, so that several surveillance cameras can be switched on at the same time and send image signals to the various screens or can be displayed simultaneously or sequentially on one screen (picture in picture).
  • Infrared-sensitive cameras can also be used as cameras, so that even in poor visibility conditions, for example at night, it is possible to monitor the area to be monitored if an infrared light source is available.
  • the device for monitoring has a video recorder which can be switched on by the receiving device 18, for example via an infrared signal. After switching on the video recorder, the receiving device supplies the signals sent by the surveillance camera to the video recorder for recording. After the end of the transmission of the signals from the surveillance camera to the receiving unit, the video recorder can be switched off, preferably again via an infrared signal.
  • the receiving device described can also be operated independently of the television set. It can be connected to standard TV sets via a - usually available - SCART socket.
