  However, as the security camera device has various functions, the number of devices such as sensors and light sources necessary for the security camera device and the number of control devices therefor increase. It may be necessary to install these devices separately from the camera body and to perform complicated wiring between them. Due to the recent increase in security awareness, security camera devices are increasingly installed in ordinary households, but many users of ordinary households are not familiar with electrical and electronic equipment and electrical wiring. In that case, it is difficult for the user to install a large number of devices and perform electrical wiring. In addition, installing a large number of devices at the front door or garden of a general home will damage the appearance of the house.

  The problem to be solved by the present invention is that it is possible to threaten and warn an intruder in addition to acquiring images regardless of day and night, and that installation and wiring are easy, and the number of devices that need to be installed is small It is to provide a security camera device.

  In order to solve the above problems, a security camera device according to the present invention is sensitive to infrared light and visible light, and has an imaging means for taking an image, a human sensor for detecting a human, and a light intensity detection. A light sensor, a visible light source, an infrared light source, and a control means for controlling them, and a voice alarm means, and the light intensity detected by the light sensor is a set value. If it is lower, the infrared light source is turned on to allow the image pickup means to take an image, and when the human sensor detects a person, the visible light source is turned on for a certain period of time and a sound is emitted from the alarm means. The gist is to give a warning.

  Here, the alarm means may be provided in the housing.

  Alternatively, the housing further includes wireless signal transmission means, and the alarm means is provided in a remote alarm unit independent of the housing together with the wireless signal receiving means, and when the human sensor detects a human being It is also conceivable that the wireless signal transmitting means transmits a wireless signal, the wireless signal receiving means receives the wireless signal, and a sound is emitted from the alarm means.

  The security camera device further includes face recognition means for detecting a skin exposure amount of a human face and face concealment notification means for emitting sound or light, and the human face recognition detected by the human sensor. When the exposure amount of the facial skin detected by the means is lower than the set value, it is preferable to notify the outside by the face concealment notification means.

  Furthermore, the sound emitted from the alarm device is preferably an electronic siren sound.

  Alternatively, the sound emitted from the warning means can be a warning voice by a human voice recorded in advance.

  According to the security camera device according to the invention, an image is taken by the imaging means, and when the presence of the intruder is detected by the human sensor, threats and warnings are given to the intruder by the visible light source and the warning means. , Can prevent the intrusion of suspicious people. In addition, the imaging means is also sensitive to infrared light, and it is possible to shoot with the imaging means even at night by turning on the infrared light source at night after judging whether the light sensor is day or night, Together with monitoring by the human sensor, night theft can be effectively prevented. In addition, it is possible to easily install and wire a security camera device by providing an image pickup means, a human sensor, an optical sensor, a visible light source, an infrared light source, and a control means for controlling them all in one housing. Even those who are not familiar with electrical and electronic equipment and electrical wiring can easily install it. Furthermore, since all the above-mentioned members are provided in one housing, the number of devices that need to be installed is less than when either one is installed as a separate body. Hard to damage the appearance.

  Here, when the alarm means is provided in the casing together with the members such as the image pickup means, the number of devices that need to be installed is further reduced, so that the installation is further facilitated and the appearance of the house and the like is further unlikely to be damaged.

  Alternatively, if the alarm means is provided separately from the housing provided with the member such as the image pickup means and generates an alarm by wireless communication, the alarm means is a security camera device body provided with the image pickup means and the like. Since it can install in a remote place, the freedom degree of an installation place is raised.

  The security camera device further includes a face recognition means for detecting the skin exposure amount of the human face and a face concealment notification means, and notifies the outside when the detected skin exposure amount of the human face is lower than the set value. Therefore, since suspicious persons such as night thefts often conceal their faces with sunglasses or masks, it is possible to distinguish suspicious persons such as night thefts from householders and visitors. In addition, by informing the user of the security camera device of the intrusion of a human who conceals the face, the user can quickly take measures by, for example, checking the image taken by the imaging means on the monitor. .

  Furthermore, when the sound emitted from the alarm means is an electronic siren sound, it is possible to effectively give intimidation and warning to the intruder, and to notify the inhabitants and passers-by that the intruder has been detected. The electronic siren sound is particularly effective in that it can be heard clearly even from a distance and has a high alerting effect.

  Similarly, when the sound emitted from the warning means is a warning voice that is recorded in advance by human voice, it effectively gives intimidation and warning to the intruder and also detects the intruder in the house and passers-by. Can be informed. In particular, in the case of a warning voice by human voice, it is possible to give a specific warning to an intruder depending on the content, and to alert a family member or a passerby to the specific content. Is possible.

  Hereinafter, the security camera device according to the first embodiment of the present invention will be described in detail with reference to the drawings. First, based on FIG.1 and FIG.2, the outline | summary of the structural member of the security camera apparatus concerning this embodiment is demonstrated.

  The security camera device body 1 has a casing 2 having a circular front surface. On the front side upper side of the housing 2, a flange portion 2 a protruding forward is provided, and raindrops, snowflakes, etc. are attached to the front of the camera module 4, the human sensor 7, and the optical sensor 8 which will be described later. Preventing intruder detection and light intensity detection from being hindered.

  At the center of the housing 2, a camera module 4, which is an imaging means, is arranged with the imaging lens facing the front side of the security camera device body 1. The camera module 4 needs to have sensitivity not only in the visible region but also in the infrared region so that image acquisition using infrared light as a light source can be performed at night. As the camera module 4, a CCD camera corresponding to the infrared region can be exemplified. In order to obtain a good image both day and night, it is desirable to provide a switchable between a visible light photographing mode (color photographing mode) and an infrared light photographing mode. In this case, images are acquired in the visible light shooting mode during the day when the light intensity detected by the light sensor described later is strong, and infrared light shooting mode is used at night when the light intensity detected by the light sensor is weak. The camera module 4 is controlled so as to acquire an image at. In addition, the camera module 4 can perform various settings such as a photographing magnification and a focal length by so-called on-screen display (OSD) so that a user who is not familiar with electrical and electronic equipment can easily perform various settings. Good.

  A human sensor 7 is provided above the camera module 4. The human sensor 7 detects the presence of a human and is provided for the purpose of determining the presence or absence of an intruder. Any type of sensor can be applied as long as it can detect the presence of human beings. However, infrared light or ultrasonic waves that are irradiated forward and reflected from a moving object are reflected. Examples include a Doppler sensor that measures a wavelength shift due to the Doppler effect in sound waves, a pyroelectric infrared sensor that detects thermal infrared rays generated by a living body, and the like. In either case, since the magnitude of the detected object can be determined based on the intensity of the detected signal, it is possible to distinguish small animals such as dogs and cats from humans. A Doppler sensor is particularly suitable from the viewpoint of detection sensitivity and simplicity.

  An optical sensor 8 is installed below the camera module 4. This detects the intensity of ambient light. Thereby, it is possible to determine whether day or night. When the intensity of the light detected by the optical sensor 8 is small, it is determined that it is night, and the infrared LED 5 described below is turned on. The optical sensor 8 may be anything as long as it can detect light intensity and convert it into an electrical signal, but a semiconductor optical sensor such as a CDS sensor or a photodiode is suitable. In particular, a CDS sensor is preferable in that it has high sensitivity to visible light. The detectable distance may be about 5 m for the purpose of detecting a suspicious person entering the house.

  Around the camera module 4, white LEDs 6 are arranged in a circle around the position of the camera module 4 as a visible light source. The white LED 6 is lit for a certain time when an intruder is detected by the human sensor 7. By irradiating the intruder with visible light, it is easy for the housekeepers and passers-by to see the presence of the intruder, and it is possible to threaten the intruder by irradiating the intruder with a powerful light beam suddenly. . In addition, the intruder is warned by informing the intruder that the security camera device is present and detected by the security camera device, and the intruder abandons the intrusion to the inside of the house etc. Also have. Here, since the plurality of white LEDs 6 are arranged in a circular shape, the surroundings can be illuminated in a wide range, and these effects are enhanced, and the security camera device body 1 as a whole is also reduced in size. doing.

  Outside the white LED 6, a plurality of infrared LEDs 5 as infrared light sources are arranged in a circular shape around the position of the camera module 4 as in the case of the white LED 6. The infrared LED 5 serves as a light source for acquiring an image by the camera module 4 at night. The infrared LED 5 is turned on when the light intensity detected by the optical sensor 8 is equal to or lower than a set value. Since the plurality of infrared LEDs 5 are arranged around the camera module 4 with high symmetry, the camera module 4 can shoot an image with spatially uniform brightness. In addition, the infrared LED 5 and the white LED 6 are arranged concentrically, thereby contributing to downsizing of the entire security camera device body 1.

  In addition, although LED is employ | adopted as both an infrared light source and a visible light source, another kind of light sources, such as an incandescent lamp, can also be used. However, the LED is optimal in that it has high brightness, a long life, and requires a small installation space. In this embodiment, two types of infrared LED 5 and white LED 6 are provided independently. However, one type of LED capable of emitting both infrared light and visible light by switching is provided instead. You can also.

  A glass window 3 is provided on the front surface of the housing 2. Among the members described above, the camera module 4, the optical sensor 8, the infrared LED 5, and the white LED 6 other than the human sensor 7 are all disposed inside the glass window 3. Thereby, even when the security camera device main body 1 is installed outdoors, it is possible to prevent these members from being contaminated and the function exerted from being deteriorated. On the other hand, the human sensor 7 is provided with the detection portion exposed to the outside of the glass window 3. The infrared LED 5 is provided inside the glass window 3 and the human sensor 7 is provided outside the glass window 3, so that the human sensor 7 is a Doppler sensor using infrared rays or a pyroelectric sensor based on the principle of infrared detection. Even in this case, the disturbance of the operation of the human sensor 7 due to the light emission of the infrared LED 5 is prevented.

  A slit 10 is provided on the side surface of the housing 2, and a speaker of the alarm means 11 (not shown in FIGS. 1 and 2) is installed inside the slit 10. When the presence sensor is detected by the human sensor 7, the alarm means 11 emits an alarm sound. Accordingly, intimidation and warning are given to the intruder in combination with the light irradiation by the white LED 6, and the intruder can be complimented to enter further inside the house or the like. In addition, the presence of an intruder can be notified to a householder or a passerby.

  An electronic siren sound can be exemplified as the alarm sound emitted by the alarm means 11. In general, the electronic siren sound is clearly transmitted to a distant place, and can strongly call attention to the occurrence of an abnormal situation.

  Alternatively, the warning means 11 may emit a warning voice such as “What are you doing there” or “I found a suspicious person” by a human voice recorded in advance? . In this case, a warning with specific contents can be given to the intruder, and the specific contents of the abnormal situation that the suspicious person has entered the house can be notified to the housekeeper and the passerby. The alarm sound can be recorded in advance by connecting a microphone to the control means 12 inside the housing 2.

  A cable bundle 9 extends from the rear of the housing 2. The cable bundle 9 is a bundle of a plurality of cables, and includes a power cable for supplying power to the camera module 4, the light sources 5 and 6, the sensors 7 and 8, and the control means 12 described later. The cable bundle 9 also includes a camera cable for sending an image captured by the camera module 4 to an external monitor or recording device.

  Although not shown in FIGS. 1 and 2, data receiving means 13 for receiving infrared signals is provided behind the housing 2. This is to receive an infrared signal from a remote control means (remote controller) 16.

  A control means 12 for controlling each of the above members is provided inside the housing 2. The relationship between the control means 12 and each member is shown in the block diagram of FIG. The control means is for controlling the camera module 4, the sensors 7 and 8 and the light sources 5 and 6 to cooperate with each other, and can be exemplified by a micro control unit (MCU) equipped with a microcomputer.

  The control means 12 receives electrical signals from the optical sensor 8 and the human sensor 7, and outputs control signals to the infrared light source 5, visible light source 6, alarm means 11 and camera module 4 based on the input signals. And control them. Further, the control means 12 includes a state counter that measures the time during which the infrared light source 5 and the visible light source 6 are in the on state or the off state, and an alarm counter that measures the time during which the alarm means 11 generates the alarm sound. ing. The infrared light source 5 and the visible light source 6 are controlled by the light source control unit 14 based on a signal from the control means 12. Further, the control unit 12 receives a signal received from the remote control unit 16 by the data receiving unit 13, and based on the signal, the infrared light source 5, the visible light source 6, the alarm unit 11, the light sensor 8, and the human sensor 7 are respectively set. While controlling, the setting time of a status counter and an alarm counter can be set.

  Infrared light source 5, visible light source 6, alarm means 11, optical sensor 8, human sensor 7, control means 12, data receiving means 13, infrared light source 5, visible light source 6, and light source controller 14 are all common substrates. 15 on board. As a result, a multi-function security camera device capable of performing nighttime image capturing using infrared light as a light source and light and voice threats and warnings when an intruder is detected is housed in a single housing 2. It is realized as a device. There is no need for the user to separately install an infrared light source, a visible light source, and an alarm means configured separately. In addition, the above-described members are mounted on a common substrate 15, and the infrared light source 5 and the visible light source 6 are concentrically arranged around the position of the camera module 4, thereby saving space. The entire housing 2 that houses the module 4 and the substrate 15 can be reduced in size.

  Next, the operation of the security camera device according to the present embodiment will be described based on the block diagram of FIG. 3 and the flowchart of FIG.

  After the power is turned on, the system is initialized in step S0. At this time, the infrared light source 5 and the visible light source 6 are turned off by the light source control unit 14.

  Next, the light intensity is measured by the optical sensor 8 in step S1. If the light intensity is higher than a set value A, it is determined that it is daytime, the process moves to step S2, and the camera module 4 is set to the visible light photographing mode. Further, the infrared light source 5 is maintained in a light-off state. Further, the state counter of the control means 12 is reset. On the other hand, if the light intensity measured in step S1 is lower than the set value A, it is determined that it is nighttime, the process moves to step S3, the infrared light source 5 is turned on, and the camera module 4 is in the infrared light shooting mode. Set to Further, the state counter of the control means 12 is reset.

  Subsequent to steps S2 and S3, step S4 is executed. Here, after the state counter is reset, it is determined whether or not the fixed time B has passed while the infrared light source 5 and the visible light source 6 are in the same state, and if so, the process proceeds to step S5. If the fixed time B has not elapsed, the process proceeds to step SA and returns to step S1. In this series of steps, it is determined whether it is daytime or nighttime, and settings suitable for each are made. Here, 3 seconds can be exemplified as the time B measured by the state counter.

  In step S <b> 5, the control unit 12 receives an output from the human sensor 7. If the human sensor 7 does not detect a signal derived from a human, it is determined that there is no intruder and the process proceeds to step SA and returns to step S1. On the other hand, when an intruder is detected by the human sensor 7, step S6 is executed. That is, the visible light source 6 is turned on by the light source control unit 14 that has received a signal from the control means 12. Next, step S7 is executed, the alarm means 11 is activated by the control means 12, and an electronic siren sound or a recorded warning sound is emitted.

  If the passage of the predetermined time C from the start of alarm generation is not measured by the alarm counter of the control means 12, step S9 is executed. That is, the control means 12 receives the output of the human sensor 7 and confirms whether or not an intruder has been detected. If an intruder is detected, the alarm counter is reset in step S10, and the process returns to step S8. That is, it is determined that the intruder continues the intruding action despite the warning by the warning means 11, and the generation of the warning is continued.

  On the other hand, when the passage of the predetermined time C is measured by the alarm counter in step S8, the process proceeds to step S11. That is, it is determined that the suspicious person has stopped the intruding action, and the visible light source 6 is turned off and the warning by the warning means 11 is stopped. In addition, the state counter is reset. Thereafter, the process proceeds to step SA. The operation time C of the alarm means 11 measured by the alarm counter can be exemplified by 20 seconds that is considered to be a time sufficient for causing an intruder, a housekeeper, or a passerby to recognize the alarm sound.

  As described above, the control unit 12 controls the camera module 4, the visible light source 6, the infrared light source 5, and the alarm unit 11 based on the outputs of the optical sensor 8 and the human sensor 7.

  In the security camera device main body 1 according to the present embodiment, all members including the camera module 4, the two types of light sources 5 and 6, and the two types of sensors 7 and 8 are incorporated in a single casing 2. Therefore, the user can start using the security camera device body 1 by simply installing the security camera device body 1 at a desired location, connecting the power cable to the power source, and connecting the camera cable to the monitor or recording device. Step S0 is automatically executed after the power is turned on.

The security camera device includes a remote control means 16 in addition to the main body 1, which can be used to preset the times B and C measured by the status counter and the alarm counter. Moreover, the visible light source 6 and the alarm means 11 can be turned ON / OFF independently of the control step according to the flowchart of FIG. For example, when the user himself / herself finds an intruder earlier than the human sensor 7 detects, threatening and warning are performed, or the human alarm sensor 7 reacts to generate an alarm sound and the visible light source 6. When the user himself confirms that the suspicious person has dissipated after is automatically turned on, the alarm means 11 and the visible light source 6 can be turned off. Further, the human sensor 7 and the optical sensor 8 can be turned ON / OFF using the remote control means 16.

  In the first embodiment, the alarm means is incorporated inside the housing of the security camera device body including the camera module and the human sensor, but the installation location of the security camera device body and the living space of the user are different. In some cases, it may be advantageous to be able to install alarm means at a location different from the security camera device main body, such as when away from the camera. From this point of view, the security camera device according to the second embodiment of the present invention is not provided with the alarm generation device in the housing of the security camera device body but is provided separately.

  FIG. 5 shows a block diagram of a security camera device according to the second embodiment. The alarm means is not provided on the substrate 35 of the security camera device main body 21 but is provided in the remote alarm unit 39 instead. Information transmission between the security camera device main body 21 and the remote alarm unit 39 is performed by a high-frequency wireless signal. Therefore, the wireless signal transmission means 36 is provided on the substrate 35 of the security camera apparatus main body 21, and the wireless signal reception means 38 is provided in the remote alarm unit 39. The wireless communicable distance may be about 100 m when use in a house is assumed. As the frequency of the high-frequency radio signal, 315 MHz, which is a frequency for a weak radio signal, is preferable. If a wireless LAN is used, it is possible to transmit a signal farther away.

In the remote alarm unit 39, the signal received by the wireless signal receiver 38 is sent to the alarm controller 37. The alarm control means 37 is a micro control unit (MCU), and controls the alarm means 31. Other configurations are the same as those of the security camera device according to the first embodiment.

  FIG. 6 is a flowchart showing the operation of the security camera device according to the present embodiment. The difference from the first embodiment of FIG. 4 is that wireless data is first transmitted by the wireless signal transmitting means 36 in step S27a and received by the wireless signal receiving means 38 in step S27b. . When the wireless signal is received by the wireless signal receiving means 38, the warning control means 37 generates an alarm by electronic siren sound or sound recording from the alarm means 31 in step S27c. Secondly, the difference from the case of the first embodiment is that, when the alarm counter of the control means 32 of the security camera device main body 21 measures a certain time C in S28, the radio signal is the radio signal transmission means 36 in step S31a. And is received by the wireless signal receiving means 38 in step S31b. When the signal is received by the wireless signal receiving unit 38, the alarm is stopped by the alarm control unit 37 in step S31c. In parallel with this, in step S31d, the visible light source 26 is turned off and the state counter is reset by the control means 32 of the security camera device body 21.

  In the above two embodiments, when the human sensor reacts, the visible light source is turned on and an alarm sound is generated. However, there may be a case where the human sensor reacts to a householder or a visitor. From this point of view, it is desirable that the security camera apparatus has a function capable of detecting a characteristic peculiar to the suspicious person. For this purpose, the security camera device according to the third embodiment is provided with face recognition means.

  People who infiltrate other people's homes for illegal purposes, such as night theft, generally hate to be seen by family members or passersby or photographed by security cameras. There are many. Therefore, by measuring the exposure amount of the skin of the face by the face recognition means, the suspicious person can be distinguished from the householder and the passerby based on the amount.

  FIG. 7 shows a block diagram of a security camera device according to the third embodiment. The camera has the same configuration as that of the security camera apparatus according to the second embodiment except that the face recognition means 60 and the face concealment notification means 61 are provided on the substrate 55 of the security camera apparatus body 41.

  Any device can be used as the face recognition means 60 as long as it can recognize the exposure amount of the target skin. For example, an infrared sensor such as a pyroelectric sensor can be exemplified. The more the face is exposed, the more heat released from the skin is detected. Therefore, if the amount of detected heat is smaller than a set value, it can be determined that the face is concealed. If an infrared sensor such as a pyrothermal sensor is used as the human sensor 47, the human sensor 47 can also serve as the face recognition means 60. Alternatively, the face recognition means 60 may analyze the face image taken by the camera module 44 and calculate the amount of skin exposure. However, from the viewpoint of simplicity, it is preferable to use an infrared sensor. The determination result by the face recognition means 60 is input to the control means 52 as an electrical signal.

  The control means 52 causes the face concealment notification means 61 to display the presence / absence of face concealment by the face recognition means 60 that has been input. As the face concealment notification means 61, for example, a set of a red warning lamp 61a and a green warning lamp 61b can be exemplified. If it is determined that the face is concealed, the red warning light 61a is turned on, and if it is determined that the face is not concealed, the green warning light 61b may be turned on. The face concealment notification unit 61 may be a voice notification unit.

  FIG. 8 shows a flowchart of the operation of the security camera device according to the present embodiment. Here, the face concealment notification means 61 is configured as a set of a red warning light 61a and a green warning light 61b. The difference from the case of the second embodiment in FIG. 6 is that after detecting an intruder by the human sensor 47 in step S45a, the face recognition means 60 is activated to determine whether or not the face is hidden. If it is determined that the face is concealed, the control means 52 turns on the visible light source 46 in step S46a, and turns on the red warning lamp 61a in step S46b. On the other hand, if it is determined that the face is not concealed, the visible light source 46 is turned on in step S46c by the control means 52, and the green warning lamp 61b is turned on in step S46d. After step S46b or step S46d, wireless data is transmitted and received in steps S47a and S47b, and an alarm sound is emitted in step S47c.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention. For example, the alarm means is provided only in the housing of the security camera device main body in the first embodiment, and is provided only in an independent remote alarm unit in the second embodiment. However, the security camera device main body and the remote alarm unit are provided. It is also possible to adopt a configuration in which alarm means are provided on both. In this case, the alarm means of the security camera device main body can be specialized for intimidation and warning directed at the intruder, and the alarm means of the remote alarm unit can be specialized for notification to householders and the like.

  In the third embodiment, the alarm means generates an alarm sound both when the face of the detected person is concealed and when it is not concealed, but does not conceal the face such as a householder. If it is not desired that an alarm sound be generated when a person is detected, the alarm sound may be generated only when face concealment is detected. Further, the face concealment notification means may be provided as a separate body instead of being provided in the security camera device body.
