Abstract

PROBLEM TO BE SOLVED: To provide a stealthy photographing detecting device which is generally practical and can inexpensively and continuously detect stealthy photographing. SOLUTION: Frequency information equivalent to the respective channels of TV broadcast are sequentially transmitted to a TV tuner unit by the processings of steps S2 to S7. When an AFT signal exists as the result of a check in the step S5, it is checked whether the channel 'has broadcast' or not (S9). When the channel 'has broadcast', a TV broadcast radio wave is regular. When the channel 'does not have broadcast', the radio wave (broadcast) detected by the AFT signal is not the regular TV broadcast radio wave, and it is highly probably a stealthy photograph radio wave radiated from the transmitter of a stealthy photograph system. Thus, stealthy photographing is performed in such a case, a green lamp 4 is turned out (S10) and a red lamp 5 is lighted (S11).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voyeur detection device for detecting the presence of a voyeur system.

[0002]

2. Description of the Related Art In recent years, cases of voyeurism have been increasing, and have been taken up as a social problem. With it,
Many women are worried about voyeurism in public facilities such as public toilets, and department stores regularly check voyeurism in toilets and changing rooms in stores.
A method often used in voyeurism is a method of transmitting an image of an ultra-small CCD camera by a transmitter of a TV broadcast wave and receiving the electric wave by a television receiver or a video device at a remote place. If a voyeur is performed in this way, the person who installed it cannot be identified unless it is a current criminal, and a very small CCD
It is also difficult to find cameras and transmitters.

[0003] In order to detect the existence of such a voyeur system, a professional radio wave detector has come to appear.
However, professional radio wave detectors are expensive, and their use is complicated, requiring radio knowledge, and is difficult for ordinary people to operate. For this reason, when a store or the like performs voyeur detection, the actual situation is that a professional company using these professional models is outsourced.

[0004]

However, if the voyeur detection is entrusted to a professional who uses the above-mentioned professional model, not only is it expensive to carry out the detection work of the trader, but also the cost is high. Even if the device detects any radio waves, the radio waves are unrelated to TV broadcast waves,
Even TV broadcast waves are overwhelmingly often regular broadcast waves unrelated to voyeurism. For this reason, even if the voyeur detection is entrusted at a high cost, there is a disadvantage in terms of cost.

[0005] In addition, the voyeur device may be installed at any time. Therefore, even if the voyeur device cannot be found by a single detection operation, there is no guarantee of safety thereafter, and it is necessary to periodically detect the voyeur device. Therefore, in order to secure the security against voyeurism, periodic patrol detection is required, which requires a large cost.

Further, some recent voyeur devices are equipped with a human body detection sensor (infrared sensor) or the like, and do not emit voyeur radio waves unless a person comes close to the device. In that case, there is no radio wave unless the detector accidentally approaches the sensor.
It is difficult to find even if it is detected by the professional radio wave detector.

The present invention has been made in view of such conventional problems, and provides a voyeur detection device which is practical for general use and which can continuously detect voyeur at low cost. The purpose is.

[0008]

According to a first aspect of the present invention, there is provided a voyeur detecting apparatus according to the present invention, wherein: a receiving means for receiving a radio wave; and a frequency of the radio wave received by the receiving means. Reception control means for sequentially and repeatedly changing radio wave information, storage means for storing radio wave information in advance, comparison means for comparing radio waves received by the reception means with radio wave information stored in the storage means, Notification control means for controlling notification means for notifying that voyeurism has been performed in accordance with the comparison result of the means.

Therefore, after the radio wave information is stored in the storage means in advance, the voyeur detection device is placed in a place where the voyeur device may be arranged, for example, in a public facility such as a public toilet or a locker room in a store. Is placed. In this arrangement, the reception control means sequentially and repeatedly changes the frequency of the radio wave, and the reception means receives the radio wave of the frequency changed by the reception control means. Then, the comparison unit compares the radio wave received by the reception unit with the radio wave information stored in the storage unit, and the notification control unit controls the notification unit according to the comparison result of the comparison unit. Therefore, by simply arranging the voyeur detection device at a location where the voyeur device may be arranged, it is possible to continuously detect the voyeur at low cost, thereby continuously ensuring the security against the voyeur. It is possible to secure.

According to a second aspect of the present invention, in the voyeur detection device according to the present invention, the reception control means sets a frequency of a radio wave received by the reception means to each broadcast channel received by the television receiver. Corresponding frequencies are sequentially set, the storage unit stores the presence or absence of broadcasting for each broadcast channel as the radio wave information, and the notification control unit receives the reception based on the comparison result of the comparison unit. When there is no broadcast on the channel corresponding to the frequency of the radio wave, the notification means is operated.

That is, the most common use in voyeurism is to transmit the image of an ultra-small CCD camera with a transmitter for TV broadcast waves and receive the radio waves (voyeur radio waves) with a television receiver or video device at a remote location. How to Therefore, the frequency of the radio wave transmitted from the transmitter is one of the frequencies corresponding to each broadcast channel received by the television receiver. However, it also includes radio waves of regular broadcasting. Therefore, the presence / absence of broadcasting for each broadcast channel is stored in the storage unit as radio wave information, and the radio wave information of this storage unit is compared with the radio wave received by the receiving unit. Then, when there is no broadcast on a channel corresponding to the frequency of the radio wave received by the receiving means, it is extremely likely that the radio wave is not a regular broadcast radio wave but a voyeur radio wave. Therefore, in this case, the notification means is operated to notify that the camera is being stolen.

According to a third aspect of the present invention, in the voyeur detection device according to the present invention, the reception control means sets a frequency of a radio wave received by the reception means to each broadcast channel received by the television receiver. Corresponding frequencies are sequentially set, the storage unit stores the radio wave intensity of the broadcast for each broadcast channel as the radio wave information, and the broadcast control unit receives the radio wave intensity based on the comparison result of the comparison unit. When the received radio wave is stronger than the radio wave intensity stored in the storage unit, the notification unit is operated.

[0013] That is, as described above, the most frequently used voyeurism is to transmit the image of an ultra-small CCD camera with a transmitter for TV broadcast waves and receive the radio waves with a television receiver or video device at a remote location. How to Therefore, the frequency of the radio wave transmitted from the transmitter is one of the frequencies corresponding to each broadcast channel received by the television receiver. However, it also includes radio waves of regular broadcasting. Therefore, the radio wave intensity of the broadcast is stored for each broadcast channel as the radio wave information, and the radio wave information of this storage unit is compared with the radio wave received by the receiving unit. At this time, if a voyeur is taken nearby, the intensity of the voyeur radio wave is higher than the intensity of the radio wave of a regular broadcast. Therefore, if the radio wave received by the receiving unit is stronger than the radio wave intensity stored in the storage unit,
It is very likely that it is not a legitimate broadcast wave but a voyeur radio wave. Therefore, in this case, the notification means is operated to notify that the camera is being stolen.

Further, the voyeur detection apparatus according to the present invention further comprises video information recording means for recording video information based on the radio wave received by the receiving means. Therefore, by reading the video information from the video information recording means and displaying it after the voyeur notification is made, it is possible to find out where the voyeur device is located based on the displayed video.

Further, the voyeur detection device according to the present invention further includes an output unit that outputs a video signal based on the radio wave received by the reception unit to an external device. Therefore, by displaying the video on the TV monitor based on the video signal output from this output means, it is possible to check the voyeur video on the external TV monitor and to promptly respond by security personnel etc. It becomes.

Further, the voyeur detection apparatus according to the present invention further comprises an output means for outputting a control signal for controlling the notification means from the notification control means to an external device. Therefore, it is possible to recognize that the voyeur device is arranged outside.

Further, in the voyeur camera detecting apparatus according to the present invention, the output means wirelessly outputs to the external device. Therefore, based on a signal wirelessly output from the voyeur detection device, in an external security room or the like, the voyeur video is confirmed on a television monitor without wiring, or a voyeur notification is performed in the security room or the like. be able to.

Further, the voyeur detection device according to the present invention according to claim 8 further comprises input means for inputting a stop control signal for stopping the operation of the notification means,
The notification control means stops the notification operation of the notification means based on the stop control signal. Therefore, after the notification is made by the notification means, the operation of the notification means can be stopped by an external operation, and the monitoring by the voyeur detection device can be resumed.

According to a ninth aspect of the present invention, the stop control signal is transmitted wirelessly, and the input means includes means for receiving the wirelessly transmitted stop control signal. Therefore, mobile phones and PHS
By using a terminal of an existing wireless communication system such as described above, the operation of the notification means can be stopped by an external operation, and the monitoring by the voyeur detection device can be resumed.

Consists of CPU, program ROM, work RAM, etc.
By operating according to the program stored in the program ROM, the entire device is controlled.

The green lamp 4 is provided by
Is lit during the detection operation, and the fact that this lamp is being lit indicates that voyeur is not being performed.
The red lamp 5 is a notification unit in the present embodiment, and is turned on when a voyeur device is detected. The alarm release switch 9 is a switch operated to release the lighting of the red lamp 5 and turn it off. Note that the notification means is not limited to a means for visually notifying such as a lamp, but may be an audible notification such as a buzzer.

The LCD display unit 6 and the key input unit 8 are used to write radio wave information for each of the broadcast channels “1” to “62” of the TV broadcast into the nonvolatile memory 11. That is, “1” is stored in the nonvolatile memory 11.
Radio information indicating whether or not a receivable broadcast is being performed at the location where the voyeur detection device 101 is arranged (“broadcast” or “no broadcast”) is stored for each of the broadcast channels “〜” to “62”. You. When the key input unit 8 is operated to write the radio wave information into the nonvolatile memory 11, characters and the like corresponding to the operation are displayed on the LCD display unit 6. Therefore,
Prior to the arrangement, the person who arranges the voyeur detection device 101 operates the key input unit 8 to input radio wave information while looking at the LCD display unit 6, and the input radio wave information is stored in the nonvolatile memory. 11 is stored. Of course, when the voyeur detection device 101 is shipped from the factory, radio wave information different for each region may be stored in the nonvolatile memory 11 in advance.

The TV tuner unit 12 includes a tuner 121 connected to the antenna 14, an IF detection / demodulation unit 122, an interface 123 with the control unit 10, and the like. Then, the radio wave of the frequency set by the control unit 10 is tuned, demodulated and detected, the video signal A is output, and the AFT signal B is output. The video signal A is output to an external monitor display 15 connected to the cord 3 as necessary, and the AFT signal B is output to the comparator 13. The comparator 13 compares the AFT signal B output from the TV tuner unit 12 with a preset reference voltage and supplies it to the control unit 10 as binary information.

On the other hand, as shown in FIG. 3, the voyeur system to be detected by the voyeur detection device 101 is an ultra-compact C
The video of the CD camera 102 is transmitted by the transmitter 103 of the TV broadcast wave, and the radio wave is received and displayed by the television receiver 104 at a remote place. Therefore, the frequency of the radio wave transmitted from the transmitter 103 is one of the frequencies corresponding to each broadcast channel received by the television receiver 104. Therefore, in the present embodiment, the presence / absence of broadcasting for each broadcast channel is stored in the non-volatile memory 11 as radio wave information, and the radio wave information of the non-volatile memory 11 and the radio wave received by the TV tuner unit 12 are stored. Are compared to detect the presence of a voyeur system.

In the operation of the present embodiment having the above-described configuration, when using the voyeur detection device 101, the voyeur detection device 101 is disposed, for example, in a public facility such as a public toilet or a dressing room in a store. Is determined in advance. Next, the person who performs the arrangement operates the key input section 8 while watching the LCD display section 6 prior to the arrangement, and selects the channel 1.
The voyeur detection device 10 for each broadcast channel
Radio wave information (“broadcasting present” or “no broadcasting”) indicating whether receivable broadcasting is being performed at the location where 1 is arranged is input. Then, the radio wave information is stored in the nonvolatile memory 11.

Next, the voyeur detection device 101 is arranged at a predetermined location, and if necessary, the voyeur detection device 101 is connected via a cord 3 to a monitor display 15 disposed, for example, in a security room. Let it be. Thereafter, when power is supplied to the voyeur detection device 101, the control unit 10 executes the processing according to the flowchart shown in FIG. 4 based on the program stored in the program ROM.

That is, first, the green lamp 4 indicating that the detection is being performed is turned on (step S1). Next, channel = 1 is set (step S2), and the frequency information (channel information) corresponding to "1" of the TV broadcast is set to the TV.
It is sent to the tuner unit 12 (step S3). Then, the TV tuner unit 12 tunes the radio wave of the frequency set by the control unit 10 from the radio wave input from the antenna 14, demodulates and detects it, outputs the video signal A, and outputs the AFT signal B Is output. At this time, if there is no broadcast wave of the “1” channel, the AFT signal B is not output naturally.

After transmitting the channel information, the control unit 10
A predetermined time corresponding to the time when the AFT signal B is established is waited (step S4), and thereafter, it is checked whether the AFT signal B is input (step S5). And
If the AFT signal B is not input, that is, if there is no broadcast radio wave of the channel, it is determined whether or not the channel being scanned has become the last channel “62” (step S6). And channel # 6
If it is 2, the value of the channel is incremented (step S7), and the processing from step S3 is repeated. If the channel becomes 62, the processing from step S2 is repeated.

As a result of the check in step S5,
If the AFT signal B is present, the radio wave information of the channel stored in advance is read from the nonvolatile memory 11 (step S8), and it is checked whether the channel is "broadcasting" (step S9). . As a result of this check, if the channel is “broadcasting”, the radio wave (broadcast) detected by the AFT signal B is not a voyeur radio wave radiated from the transmitter 103 of the voyeur system, but a registered regular radio wave. TV broadcast radio waves. Therefore, in this case, the process proceeds to step S6, and the channel scan is restarted.

However, if the result of the check in step S9 is that the channel is "no broadcast", A
The radio wave (broadcast) detected by the FT signal B is not a regular TV broadcast radio wave but a transmitter 10 of the voyeur system.
The probability of being a voyeur radio wave radiated from 3 is extremely high. Therefore, in this case, it is concluded that the camera has been stolen,
Turn off the green lamp 4 (step S1
0), the red lamp 5 is turned on (step S11).
Therefore, during the detection operation, the green lamp 4 is lit to indicate that no voyeur has been taken, and when voyeur is detected, the red lamp 5 is lit to indicate that voyeur has been taken.

Further, once the red lamp 5 is turned on, the control section 10 temporarily stops the control until the alarm release switch 9 is operated in the next step S12. Therefore, since the channel scan is not executed, the video based on the radio wave determined to be the voyeur radio wave is continuously displayed on the monitor display 15 in the security room. Therefore, by watching the image displayed on the monitor display 15 by the security guard, it is possible to confirm the contents of the radio wave (broadcast) determined to be the voyeur. That is, by comparing with the situation of the place where the voyeur detection device 101 is disposed, it can be confirmed whether or not the voyeur is actually performed. In addition, based on the image on the monitor display 15, the location where the CCD camera 102 of the voyeur system is located is located, and further, the location of the transmitter 103 connected to the CCD camera 102 is located to find these locations. Can be.

If the CCD camera 102 and the transmitter 103 of the voyeur system are found in this way, they are removed, and then the alarm release switch 9 is operated. As a result, the determination in step S12 becomes YES, and after turning off the red lamp (step S12), the processing from step S1 is repeated. Therefore, by simply arranging the voyeur detection device 101 at a predetermined location where the voyeur system is likely to be installed, it is possible to continuously detect voyeur at low cost, thereby maintaining the security against voyeur. It becomes possible to secure it.

According to the present embodiment, the use of the TV tuner unit 12 ensures that only TV broadcast waves including voyeur radio waves are received, the TV broadcast units do not react to other radio waves, and that regular TV broadcast By setting the channel of the wave in the non-volatile memory 11 in advance and comparing the detected radio wave with the detected radio wave, a legitimate TV broadcast can be excluded from the detection target, so that high-precision voyeur detection can be performed.

(Second Embodiment)

FIGS. 5 and 6 show a second embodiment of the present invention. The voyeur detection device 201 according to the present embodiment includes the voyeur detection device 10 according to the first embodiment.
1 is replaced with A as shown in FIG.
Only the point that the / D converter 16 is provided is different from the first embodiment. That is, in the first embodiment, the AFT signal B is input to the control unit 10 via the comparator 13 as binary information, whereas in the present embodiment, the radio field intensity signal C is multi-valued. The information is input to the control unit 10 via the A / D converter 16.

In the operation of the present embodiment having the above configuration, when the voyeur detection device 201 is used,
The person who performs the arrangement operates the key input section 8 while watching the LCD display section 6 prior to the arrangement, and can receive the broadcast at each location where the voyeur detection device 201 is arranged for each of the broadcast channels 1 to 62. Information indicating whether or not broadcasting is being performed (“broadcasting” or “no broadcasting”), and in the case of “broadcasting”, the radio wave intensity (signal strength) is input. Then, radio wave information including the radio wave intensity in the case of “broadcast”, “no broadcast”, and “broadcast” for each of the broadcast channels 1 to 62 is stored in the nonvolatile memory 11.

Next, the voyeur detection device 201 is arranged at a predetermined position, and if necessary, the voyeur detection device 201 is connected to the monitor display 15 disposed in a security room, for example, via a cord 3. Let it be. Thereafter, when power is supplied to the voyeur detection device 201, the control unit 10 executes processing in accordance with the flowchart shown in FIG. 6 based on the program stored in the program ROM.

That is, first, the green lamp 4 indicating that the detection is being performed is turned on (step S21). Next, channel = 1 is set (step S22), and frequency information (channel information) corresponding to “1” of the TV broadcast is set to T.
It is sent to the V tuner unit 12 (step S23).
Then, the TV tuner unit 12 is connected to the antenna 14
Out of the radio waves input from the control unit 10, the radio wave of the frequency set by the control unit 10 is tuned, demodulated and detected, the video signal A is output, and the radio wave intensity signal C is output. At this time, if there is no broadcast radio wave of the “1” channel, the radio wave intensity signal C is not output.

After transmitting the channel information, the control unit 10
After waiting for a predetermined time (step S24), it is checked whether or not the radio wave intensity signal C has been input (step S25). Then, when the radio wave intensity signal C is not input, that is, when there is no broadcast radio wave of the channel, it is determined whether or not the scanning channel has become the last channel “62” (step S2).
6). If channel # 62, the value of the channel is incremented (step S27), and the processing from step S23 is repeated. If channel = 62, the processing from step S22 is repeated.

If the result of the check in step S25 indicates that there is a radio wave intensity signal C, the nonvolatile memory 1
The radio wave information of the channel stored in advance is read out from step 1 (step S28), and the intensity of the received radio wave indicated by the radio wave intensity signal C and the radio wave intensity (signal intensity) of the channel stored in the nonvolatile memory 11 are read. Are compared (step S29). As a result of this comparison, the strength indicated by the radio wave intensity signal C is equal to the stored radio wave intensity (signal strength) of the channel, or the strength indicated by the radio wave intensity signal C is equal to the stored radio wave of the channel. If the signal strength is lower than the signal strength (signal strength),
The radio wave (broadcast) detected in is not the voyeur radio wave radiated from the transmitter 103 of the voyeur system,
It is determined that the registered TV broadcast wave is registered. Therefore, in this case, the process proceeds to step S26, and the channel scan is restarted.

However, as a result of the check in step S29, when the strength indicated by the radio wave intensity signal C is higher than the stored radio wave intensity (signal strength) of the corresponding channel, it is detected by the radio wave intensity signal C. The radio wave (broadcast) is not a regular TV broadcast wave, but has a very high probability of being a voyeur radio wave radiated from a transmitter 103 of a nearby voyeur system. Therefore, in this case, it is determined that the camera is being voyeurized, the green lamp 4 is turned off (step S30), and the red lamp 5 is turned on (step S31). Therefore, during the detection operation, the green lamp 4
Lights to indicate that voyeurism has not been performed, and upon detection of voyeurism, the red lamp 5 lights to indicate that voyeurism has been performed.

Further, once the red lamp 5 is turned on, the control unit 10 temporarily suspends the control until the alarm release switch 9 is operated in the next step S32. Therefore, since the channel scan is not executed, the monitor display 15 in the security room keeps displaying an image based on the radio wave determined to be the voyeur radio wave. Therefore, by watching the image displayed on the monitor display 15 by the security guard, it is possible to confirm the contents of the radio wave (broadcast) determined to be the voyeur. That is, by comparing with the situation of the place where the voyeur detection device 201 is arranged, it can be confirmed whether or not the voyeur is actually performed. Further, based on the image on the monitor display 15, the CCD camera 10 of the voyeur system is used.
2 is located, and furthermore, CCD
The location of the transmitter 103 connected to the camera 102 can be located and found.

In this way, if the CCD camera 102 and the transmitter 103 of the voyeur system are found, they are removed, and then the alarm release switch 9 is operated. As a result, the determination in step S32 becomes YES, and after turning off the red lamp (step S32), the processing from step S21 is repeated. Therefore, by simply arranging the voyeur detection device 201 at a predetermined location where the voyeur system may be arranged, it is possible to continuously detect the voyeur at a low cost, thereby maintaining the security against the voyeur. It becomes possible to secure it.

According to the present embodiment, the use of the TV tuner unit 12 ensures that only TV broadcast waves including voyeur radio waves are received, that the TV broadcasters do not react to other radio waves, and that regular TV broadcasts are not received. By setting the channel of the wave and its radio wave intensity in the nonvolatile memory 11 in advance, and comparing the detected radio wave with the detected radio wave, it is possible to exclude a legitimate TV broadcast from the detection target, thereby enabling high-precision voyeur detection.

In such a configuration, the video signal A from the TV tuner unit 12 is always stored in the video memory 17. Further, as described in the flowchart of FIG. 4, once the red lamp 5 is turned on, the control unit 10 temporarily stops the control until the alarm release switch 9 is operated in the next step S12. Therefore, since the channel scan is not executed, the capture of the image is stopped in the video memory 17 when the voyeur is detected, and the video at the time of the voyeur remains in the video memory 17. Therefore, a voyeur system equipped with a human body detection sensor (infrared sensor) and the like does not emit a voyeur radio wave unless a person is approaching immediately.

Since it has been notified that the voyeur is detected, simply by arranging this voyeur detection device at a place where the voyeur device may be arranged, it is possible to continuously detect voyeur at low cost, This makes it possible to continuously ensure the security against voyeurism.

Further, while sequentially setting the frequency corresponding to each broadcast channel received by the television receiver,
The presence or absence of broadcasting is stored for each broadcasting channel, and when there is no broadcasting of the channel corresponding to the frequency of the received radio wave,
By operating the notification means, it is possible to reliably receive only television broadcast waves including voyeur radio waves, not to react to other radio waves, and to exclude regular television broadcasts from detection targets. Therefore, high-precision voyeur detection becomes possible.

Further, while sequentially setting the frequency corresponding to each broadcast channel received by the television receiver,
The radio wave intensity of the broadcast is stored for each broadcast channel, and when the received radio wave is stronger than the stored radio wave intensity, the notifying means is operated. , Which does not respond to other radio waves, and can also exclude legitimate television transmissions from detection based on the radio wave conditions at the location where the voyeur detection device is located. High-precision voyeur detection according to the radio wave condition of the arrangement location becomes possible.

Further, by further comprising video information recording means for recording video information based on the received radio wave,
After the voyeur notification, the video information can be read from the video information recording means and displayed, and the location where the voyeur device is located can be found based on the displayed video. In addition, a voyeur system equipped with a human body detection sensor (infrared sensor) and the like does not emit a voyeur radio wave unless a person comes close to the voyeur system. It is possible to confirm the fact of the voyeur based on the video recorded in the recording means.

Further, by further providing an output means for outputting a video signal based on the received radio wave to an external device, the voyeur video can be confirmed on an external television monitor, and a response by a guard or the like can be promptly performed. It is possible to do.

Further, by further providing an output means for outputting a control signal for controlling the notification means to an external device, it is possible to recognize that the voyeur device has been arranged outside, and to take quick action. It becomes possible.

Further, since the video signal based on the received radio wave and the control signal for controlling the notifying means are wirelessly output, a location away from the place where the voyeur detection device is arranged without wiring. Thus, the voyeur video can be confirmed on the television monitor, or the voyeur notification can be performed.

Further, since a stop control signal for stopping the operation of the notifying means is inputted from the outside, the notifying operation of the notifying means can be stopped. , The operation of the notification means is stopped, and the operation of restarting the monitoring by the voyeur detection device can be remotely performed.

Since the stop control signal is transmitted wirelessly, the operation of the notifying means is stopped by an external operation using a terminal of an existing wireless communication system such as a mobile phone or a PHS. Thus, it is possible to construct a system capable of continuously restarting monitoring by the voyeur detection device.
