2. Description of the Related Art Conventionally, a monitoring system using a monitoring moving image or a still image camera (surveillance camera) has been attracting attention because of an increase in security (safety) awareness and a demand for labor saving of security.
The monitoring system is a system that includes an imaging device such as a security monitoring camera, and a device that displays a still image or a moving image acquired by the imaging device.
In surveillance systems, fixed image sensors are installed in places where monitoring is required for crime prevention and disaster prevention, such as hotels, buildings, convenience stores, financial institutions, dams, or facilities visited by an unspecified number of people. A type system is often used.
In these fixed-type monitoring systems, a captured person monitors a captured image and alerts it according to the purpose and necessity, and records / stores the image.

However, since such a monitoring system is installed in a public place, it is necessary to prepare for theft of an expensive camera by a suspicious person.
For this reason, as a conventional image storage device for theft, referring to Patent Document 1, in the surveillance camera system, a surveillance camera system including prevention of theft of the camera device itself, which is a device originally intended for monitoring, is described. (Hereinafter referred to as prior art 1).
The surveillance camera system of the prior art 1 does not store the image data captured from the camera device in the camera device, but directly transmits it to the monitoring terminal via the network.
Based on this, sensors are installed on the door of the camera housing (camera case) of the camera device and the door of the control panel, and when the door is opened, alarm information is output and the control device and the location of the alarm are confirmed. A control signal is transmitted from the control device to another possible camera device, and an alarm occurrence point is photographed.
Furthermore, an alarm mail can be transmitted to an address of a monitoring system administrator's PC (Personal Computer) or a mobile phone set in advance.

On the other hand, in recent years, with the diversification of needs for image storage devices and the advancement of technology, surveillance systems using image storage devices of small size, portable type, outdoor installation type and the like have been frequently used.
In such a monitoring system, unlike the apparatus of the prior art 1, the image storage device includes an HDD (Hard Disk Drive) or the like, and can store image data captured by the camera.
An image storage device provided with such a storage unit is often installed in a place where a third party other than the user (related person) can visually recognize, and is more than a conventional fixed type monitoring system such as the prior art 1. There is a problem that there is a high risk of being damaged by operations, destruction, theft, etc. by a suspicious person other than the user.

[Configuration of Image Storage Device 10]
Next, the configuration of the image storage device 10 will be described with reference to FIG.
The image storage device 10 includes a control unit 200, a main camera unit 210, sub-camera units 221, 222, a storage unit 230, a vibration sensor 250, an open / close sensor 260, an uninterruptible power supply 280, and a power cable 285. And a wireless transmission unit 290.
Among these, the vibration sensor 250, the open / close sensor 260, and the uninterruptible power supply 280 are configured as an abnormality detection unit 500 that detects an operation abnormality such as when the image storage device 10 is subjected to destruction by a suspicious person. The

The control unit 200 is a control unit such as a CPU, an MPU, a DSP (digital signal processor), a GPU (graphic processing unit), and an image search dedicated processor. The control unit 200 controls each unit of the image storage device 10. The control unit 200 may be configured to incorporate a nonvolatile storage unit such as a ROM or a flash memory and control each unit in accordance with a program in the storage unit.
The main camera unit 210 and the sub camera units 221 and 222 are imaging devices that capture (capture) an object using a CCD (Charge Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor) image sensor, or the like. The main camera unit 210 and the sub camera units 221 and 222 may include a human sensor, a motion sensor, a microphone, and the like, for example. Further, the sub camera unit 222 may be installed in the housing of the image storage device 10 and may include a light part such as an infrared LED. Also, the captured image data can be transmitted via the network 5.
The storage unit 230 is an HDD, a flash memory, a ROM, a RAM, and the like, and includes a control program executed by the control unit 200, image data of the main camera unit 210 and sub camera units 221, 222, a vibration sensor 250, and an open / close sensor 260.

In addition, the image storage device 10 may include a siren, a flashlight, a high-voltage generator, a liquid / gas emission device, or the like that warns when vibration or opening / closing of a housing is detected.

[Monitoring system X abnormality report processing]
Here, with reference to the flowchart of FIG. 3, the image search process using the monitoring system X according to the first embodiment of the present invention will be described in more detail.
In a normal case, for example, the movable image storage device 10 is installed by an administrator, and the control unit 200 acquires a monitoring image such as a still image or a moving image as image data from the main camera unit 210 at a predetermined interval. By storing it in the storage unit 230, it operates as a recording apparatus that stores image data.
The image data of the monitoring image can be obtained by the terminal 30 via the relay device 20 and the network 5.
Here, processing when the image storage device 10 detects an abnormality by each unit will be described in detail below.

First, in step S101, the control unit 200 performs vibration detection processing.
Specifically, when vibration is detected by the vibration sensor 250, the control unit 200 uses the sub camera unit 221 to acquire the image storage device 10 and surrounding images as abnormality detection data.
Thereafter, the control unit 200 adds information such as vibration sensor data, the fact that vibration is detected, the date and time, and the ID of the image storage device 10 as necessary, to the abnormality detection data. The anomaly detection data may be encrypted, or other data may be embedded in the image data in the metadata format.
Then, the control unit 200 sends the abnormality detection data to the external relay device 20 using the wireless transmission unit 290. The relayed abnormality detection data is received by the terminal 30 via the network 5.

Here, an example in which the vibration sensor 250 specifically detects vibration will be described with reference to FIG. As described above, the vibration sensor 250 performs a destructive action such as the suspicious person P removing the fixing tool for carrying away, hitting the housing, or damaging the image storage device 10 with a saw or chisel. If so, this vibration is detected. At this time, the control unit 200 uses the sub camera unit 221 to photograph the situation of the destruction act and the suspicious person P.
Note that a plurality of vibration sensors 250 can be attached to the housing, or can detect a location where vibration is applied to the housing due to a change in vibration acceleration or the like. In this case, the control unit 200 can take an image by tracking the suspicious person P with the sub camera unit 221 directed toward the place where the vibration is applied.
Further, the auxiliary camera unit 221 can be prominently installed to threaten the destructive action of the suspicious person P. On the contrary, the sub camera unit 221 can be installed so as not to be noticed by the suspicious person P, for example, installed in the back of the wall or made inconspicuous with a protective color.

Next, in step S102, the control unit 200 performs open / close detection processing.
Specifically, when the opening / closing sensor 260 detects that the image storage device 10 has been opened, the control unit 200 acquires an image captured by the sub camera unit 221 as abnormality detection data.
Further, the control unit 200, from the inside of the image storage device 10, the direction in which the housing is opened by the sub camera unit 222, mainly an image obtained by photographing the outside of the housing, and information such as the fact that the housing has been opened, date and time, ID, etc. Is obtained as abnormality detection data in the same manner as the above-described vibration detection.
Then, the control unit 200 sends the abnormality detection data to the external device 30 to the relay device 20. At this time, the opening / closing data of the opening / closing sensor 260 is added to the abnormality detection data. In addition to this, data of the vibration sensor 250 may be added.

Here, an example of a specific case of the open / close detection process will be described with reference to FIG.
As an example in which the opening / closing sensor 260 detects opening / closing, a case where the suspicious person P opens the casing (case, casing, housing) of the image storage device 10 and the sub camera unit 222 captures the action can be considered.
With this configuration, it is possible to detect the change in the amount of light when the inside of the housing is opened and closed, and to operate the sub camera unit 222. In this case, it is possible to cope with a case where a destructive action such as destruction / short-circuiting of the open / close sensor 260 is performed. In this case, the opening / closing of the housing of the image storage device 10 can be detected without using the opening / closing sensor 260.
Further, since the sub camera unit 222 is required to have a size that can be accommodated in the image storage device 10, for example, a small camera such as a USB (Universal Serial Bus) connection camera can be used.
Furthermore, since it is desirable to make the sub camera unit 222 close to the control unit 200, it is possible to mount the sub camera unit 222 on the same board as the control unit 200 or on another board like a component. By configuring in this way, it is possible to make it difficult for the suspicious person P to recognize the presence of the sub camera unit 222, and thus it is possible to suppress disturbance of the imaging of the sub camera unit 222 by the suspicious person P.
In addition, the sub camera unit 222 can image the inside of the housing of the image storage device 10. As a result, it is possible to confirm that suspicious parts used for hacking or the like are installed inside the image storage device 10 or dangerous materials such as explosives are installed.

Next, in step S103, the control unit 200 performs a power-off detection process.
Specifically, when the uninterruptible power supply 280 detects a power cut (power cut), the uninterruptible power supply 280 performs battery backup for switching the power supply to battery operation, and notifies the control unit 200 of the occurrence of the power cut. .
The control unit 200 uses the sub camera unit 221 to acquire the image storage device 10 and surrounding images as abnormality detection data. Then, the control unit 200 adds the fact that the power is cut off to the abnormality detection data, and notifies the external relay device 20 in the same manner as in the above-described vibration detection.

Here, an example of a specific case of the power-off detection process will be described with reference to FIG.
As an example in which the uninterruptible power supply 280 detects the power interruption, there may be a case where the suspicious person P cuts the power cable 285 or more simply pulls out the plug of the power cable from the outlet.
At this time, the sub camera unit 221 captures the situation of the power cable 285 being disconnected and the suspicious person P. At this time, the casing of the image storage device 10 can be locked by a solenoid attached to the open / close sensor 260. Conversely, the solenoid associated with the open / close sensor 260 can be opened and the suspicious person P can be photographed by the sub camera unit 222 inside.

Next, in step S104, the control unit 200 determines whether or not there is an abnormality in the above-described processing. That is, it is determined whether the abnormality detection unit 500 has detected an abnormality.
More specifically, if the vibration sensor 250 detects vibration, the open / close sensor 260 detects open / close, or the uninterruptible power supply 280 detects power-off, it is determined as Yes. . Otherwise, it is determined No.
In Yes, the control part 200 advances a process to step S105.
In No, the control part 200 returns a process to step S101 and continues detection of an operation abnormality.

In step S105, the control unit 200 performs an external notification process.
Specifically, the abnormality detection data notified from the image storage device 10 is received, for example, by a relay device 20 that is a wireless LAN access point or a mobile base station, and is transmitted to the administrator via the network 5 that is the Internet. It reaches the terminal 30 which is a connected PC.
The terminal 30 is executing a web browser or a dedicated monitoring program, and can warn and display an image of the detected abnormality detection data, an abnormality state, or the like.
As a result, the administrator obtains the fact that an abnormality has occurred in the image storage device 10 and its type, date and time, related camera images, etc., and quickly takes necessary measures when an abnormality occurs, such as notification to a maintenance staff or the police. Can be taken.
Even when a suspicious person escapes, the suspicious person can be determined and investigated from the stored abnormality detection data.

Next, in step S106, the control unit 200 determines whether to stop the detection operation.
Here, after the transmission of the abnormality detection data is successful, the control unit 200 stops the detection when the operation abnormality is not detected for a predetermined time, that is, determines Yes. In addition, when the control unit 200 performs other tasks such as erasing confidential data due to the detection of abnormal operation, the storage operation is detected by a suspicious person due to the operation of the HDD, etc., battery consumption It is also possible to determine “Yes” when the operation is stopped in order to suppress this. Furthermore, it is possible to determine Yes even when the battery capacity is simply reduced to a predetermined level. Otherwise, it is determined No.
In the case of Yes, the control unit 200 ends the abnormality occurrence notification process.
In No, the control part 200 returns a process to step S101 and continues detection of an operation abnormality.

Depending on the setting of the control program executed by the control unit 200, the storage unit 230 can also store information such as an image of abnormality detection data notified at the time of the above-described abnormality notification, the value of each sensor, and ID. It is.
At this time, since the transmission / reception speed of data inside the image storage device 10 is faster than wireless communication with the external relay device 20 by the wireless transmission unit 290, high-quality video and detailed information are stored in the storage unit 230. It is possible to keep it. Further, even when the wireless transmission unit 290 is destroyed, it is possible to store an operation abnormality.
Further, it is possible to always store the image data of the sub camera unit 221 and the sub camera unit 222 even during normal operation. In this case, since the video before the abnormality detection is also stored, more detailed investigation and investigation are possible after the occurrence of the abnormality.
Thus, the abnormality occurrence notification process is terminated.

As described above, the monitoring system X according to the first embodiment of the present invention has the vibration sensor 250 when the suspicious person P actually tries to perform acts such as destruction or removal on the image storage device 10. This is detected by vibration detection or power supply interruption detection by the uninterruptible power supply 280, and the control unit 200 uses the sub camera unit 221 to photograph the periphery of the image storage device.
In addition to the captured image, information such as the captured video, date and time, and degree of vibration is transmitted to the external terminal 30 by the wireless transmission unit 290 as abnormality detection data. As the terminal 30, a mobile phone, a dedicated device connected via a wireless LAN device terminal, a PC, or the like can be used.
Further, when the housing of the image storage device 10 is opened, this is detected by the open / close sensor 260, and the control device uses the sub camera unit 222 to store an image in the external direction from the inside of the image storage device. To do. That is, the suspicious person who opened the image storage device 10 is photographed, and information such as the photographed image data, date and time, opened fact, etc. is also transmitted to the external terminal 30 by the wireless transmission unit 290 as abnormality detection data. To do.

With the configuration described above, the following effects can be obtained.
The surveillance camera system of the prior art 1 is mainly intended for fixed surveillance systems as an installation form, and measures are taken with multiple primary surveillance cameras, infrared sensors, special bolts, special locks, etc., and only the open / close sensor is installed. Used to detect abnormalities.
For this reason, the surveillance camera system of the prior art 1 mainly deals with theft prevention of the camera and the control panel.
Further, the surveillance camera system of the prior art 1 has a problem that it cannot cope with the disappearance, theft, or misuse of the surveillance video after the camera is invalidated.

In contrast, the monitoring system X according to the first embodiment of the present invention includes an open / close sensor 260, a vibration sensor 250, and an uninterruptible power supply 280 as abnormality detection means.
For this reason, the monitoring system X of the present embodiment can perform advanced antitheft measures for the image storage device 10 that is portable, portable, small, light, and temporarily installed.
That is, the monitoring system X according to the present embodiment acquires the data of each sensor as abnormality detection data, and detects the abnormality detection data at the terminal 30, so that after the financial damage theft of the image storage device 10. In addition to stopping the monitoring function, it is possible to deal with the disappearance, theft, and misuse of the surveillance video before the theft.
Further, by adding GPS as in the third embodiment described later, it is possible to cope with the case where the image storage device 10 is taken away.

Further, the surveillance camera system of the prior art 1 is an online system connected to a surveillance center via a network as an operation form.
For this reason, the surveillance camera system of the prior art 1 performs abnormality determination, instruction, and storage by monitoring a video in real time (real time) by a monitor at a remote monitoring center.
That is, when the network is disconnected, the camera becomes inoperable and data at the time of abnormality cannot be acquired.

In contrast, in the monitoring system X according to the first embodiment of the present invention, the local image storage device 10 includes the vibration sensor 250 and the open / close sensor 260 in addition to the storage unit 230, and the network 5 is disconnected. However, the control unit 200 can perform abnormality determination, operation instruction, and storage.
As a result, in the image storage device 10 that is installed in a place where access by persons other than those concerned is allowed to enter and is not in an environment where the administrator is resident in the vicinity, a deterrent effect on operation, destruction, and theft by persons other than those concerned and problems occur. Sometimes it is possible to obtain useful information for investigating and tracking suspects and image storage devices.

In addition, since the surveillance camera system of the prior art 1 only performs remote real-time video monitoring, there is no particular countermeasure against power-off.
For this reason, in the prior art 1, it was difficult to know what destructive action was performed after the power was turned off.
In other words, only when the network and the power supply are not cut off, when an abnormality is detected, camera shooting, recording, and camera shooting and recording after a report offense are possible, which is insufficient as a countermeasure against theft of portable image storage devices. there were.

On the other hand, the monitoring system X according to the first embodiment of the present invention can be backed up by the uninterruptible power supply 280, and when an outage is detected such as a power interruption, an abnormality is reported and image data is Memory is possible.
Thereby, even if the network 5 and the power cable 285 are disconnected, camera shooting, recording, and post-crime recording are possible when an abnormality is detected.
Further, by providing both the sub camera units 221, 222, an image can be stored by the threatening effect of the sub camera unit 221 and the sub camera unit 222 provided so as not to stand out even if it is destroyed. .
Further, as will be described later, by providing GPS, it is possible to track when it is taken away.

In addition, the monitoring system X according to the first embodiment of the present invention arranges the sub camera unit 221 connected to the control unit 200 of the image storage device 10 so as to photograph the image storage device 10 and its periphery.
Accordingly, it is possible to give a consciousness that an object approaching the image storage device 10 is being photographed and to obtain a deterrent effect on operations, destruction, and theft by persons other than those concerned.

In addition, the monitoring system X according to the first embodiment of the present invention transmits abnormality detection data from the wireless transmission unit 290 only when there is an abnormality, and ends the detection of the operation abnormality after a predetermined time or the like. Therefore, the effect that battery consumption can be suppressed is obtained. As a result, the image can be stored for a longer time after the detection of the abnormal operation of the image storage device 10. As a result, it becomes easy to identify a suspicious person or the like, and it is possible to perform tracking for a longer time even when GPS described later is used. Even when the power cable 285 is disconnected, it is possible to secure a longer operation time of the image storage device 10.
Furthermore, even if misoperation occurs due to mischief, periodic vibrations added by cars, trains, machines, animals, etc., changes in the locked state of the housing due to unstable installation, instantaneous power failure due to unstable power supply, etc. By returning to the normal operation abnormality detection operation as much as possible, the battery can be kept more. Furthermore, it is possible to make it difficult for a suspicious person to realize that an abnormal operation is detected by reducing the detection and notification of abnormal operation. In addition, by reducing the operating time of the operation part of the image storage device 10, it can be expected that the life of the electronic device is prolonged by suppressing fatigue and the like due to heat.
