DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, claims 1 and 5 of the present invention
A first embodiment according to claims 6 and 7 will be described. FIG. 1 is a configuration diagram showing the overall configuration of the system. The security device 10 of the present embodiment includes a home video camera 1, a monitoring terminal 2, an alarm device 3 including a rotating light 3a and a speaker 3b. Monitoring terminal 2 of this security device 10
Is connected to the center terminal 30 via the public line 20. The security system 10, the public line 20, and the center terminal 30 constitute an entire system.

The public line 20 is a line that can be used by the general public to transmit and receive data. Among the lines, a wired analog telephone line or ISDN line drawn into a general private residence or a small business establishment, or a monitoring terminal 2 includes a mobile communication line that passes from a mobile phone terminal connected to the base station to a base station. The center-side terminal 30 is a terminal for confirming the contents of monitoring, and is, for example, a personal computer disposed in a monitoring center established exclusively or a mobile phone terminal carried by an administrator. And an image can be displayed. The center terminal 30 is appropriately selected from the personal computer and the mobile phone terminal according to circumstances.

Next, details of the security device 10 will be described with reference to FIG.
This will be described with reference to FIG. FIG. 2 is a configuration diagram illustrating a configuration of the security device of the first embodiment. Monitoring terminal 2 of security device 10
Are an image processing unit 2a, a detection unit 2b, an image storage unit 2c, a signal processing unit 2d, an alarm operation unit 2e, and an interface unit 2.
f, a setting unit 2g, and an AC / DC conversion unit 2h.
The AC / DC converter 2h draws in an AC (alternating current) 100V power signal from an outlet serving as the commercial power supply 4, generates DC (direct current) power by rectification, and supplies power to each unit in the monitoring terminal 2. .

Next, various configurations of the security device 10 will be described according to the flow of signals. The home video camera 1 is fixedly installed on a tripod or a fixed base in a room such as a general private house or a small business establishment, and is set in advance so that images in a predetermined range of doors and windows can be obtained. When manager is absent in general private house, small-scale establishment,
The power supply of the home video camera 1 is set to ON to bring the camera into an imaging state, and an imaging signal is constantly output.

The reason why the power is always turned on and the imaging state is set as described above is that (1) the home video camera 1 takes a long time from when the power is turned on until the imaging signal is output to the outside. (2) For a general private house, the purpose is to prevent crime for a few hours and absence in a relatively short time when going out. The home video camera 1 is connected to an image processing unit 2a of the monitoring terminal 2 via a camera cable, and the imaging signal is input to the image processing unit 2a.

The image processing section 2a includes the home video camera 1
Is converted into an image signal in a format to be processed in the monitoring terminal 2. For example, if the imaging signal is an analog video signal, it is converted to a digital video signal. If the image signal output from the home video camera 1 can be directly used as an image signal, the image signal may be output as an image signal as it is. In this case, the image processing unit 2a performs the function of a simple interface. These image signals are branched and output to three systems: a detection unit 2b, an image storage unit 2c, and a signal processing unit 2d.

A processing system for issuing a warning to an illegal intruder will be described first among the three systems. Detector 2b
When an intruder intrudes by opening a door or a window, image processing is performed on an image signal output from the image processing unit 2a, and a moving object such as an intruder or a door (hereinafter simply referred to as a moving object) ) Is detected.

As an example of the image processing in the detection unit 2b, for example, a difference between two image signals having different times is obtained, and when there is a change, it can be determined that there is an illegal intruder. Then, the detection unit 2b outputs a detection signal to the alarm operation unit 2e. Here, for example, as in the patent invention described in Japanese Patent No. 3043457 "Monitoring Device" owned by the applicant of the present invention, after performing noise removal, image processing is performed to detect a moving object, and illegal intrusion is performed. May be recognized.

The alarm activation section 2e activates the alarm device 3 when the detection signal from the detection section 2b is input. Specifically, the rotating light 3a shown in FIG. 1 is operated to emit light suddenly and brilliantly. Alternatively, an alarm signal recorded in advance is reproduced from a reproducing device (not shown) provided in the alarm operation section 2e, and an alarm sound is emitted from the speaker 3b shown in FIG.

The alarm operating section 2e may be provided with a timer (not shown) for stopping the driving of the home video camera 1 and the operation of the alarm device 3 for a fixed period of time. In any case, the warning device 3 gives the above-mentioned warning to give a trespasser a psychological oppression and disperses the trespasser.

Next, of the three systems, a processing system for recording a trespasser will be described. Image storage unit 2c
Stores the image signal output from the image processing unit 2a after performing signal processing for storage. The signal processing for storage is, for example, signal processing for generating a compressed image signal by compressing an image signal. At the time of reproduction, the compressed image signal is expanded to generate the original image signal, and then reproduced.

By adopting such a configuration, it is possible to go out and
Even if the manager is absent in a general private house or small business due to a holiday, the burglar is captured and recorded by the security device 10, even if the burglar is stolen. Suspect specific evidence will be presented to the competent police. Therefore, prompt case resolution is expected.

Next, of the three systems, a processing system for notifying a remote place that an unauthorized intruder has entered will be described. The signal processing unit 2d converts the image signal output from the image processing unit 2a into an image transmission signal suitable for transmission. The image transmission signal is, for example, a signal generated by adding an error correction signal to the image signal. This image transmission signal is output to the interface unit 2f. The interface unit 2f transmits this image transmission signal to the center terminal 30 via the public line 20, as shown in FIG.

The center side terminal 30 may be a mobile phone terminal stored by a manager such as an owner of a general private house or a small business, or a personal computer at the office of a manager of a general private house. And can be. In any case, since the image transmission signal is transmitted to the center terminal 30 via the public line 20, the administrator can immediately know the abnormality.

Further, although not shown, instead of connecting the interface unit 2f to the public line 20, an RS-23
For example, a personal computer at a nearby acquaintance's house is connected via a 2C communication line or the like, and an image transmission signal from the interface unit 2f is transmitted to the personal computer at the acquaintance's house, and the acquaintance promptly reports to the police in charge. You can also. Although these configurations are appropriately selected, the security device 10 is adapted to be able to cope with any case, and enhances the convenience for the user.

Is given by a command signal transmitted from the center terminal 30.
Switching between a monitoring start instruction and a monitoring end instruction can be performed. When a monitoring end instruction is issued from the center terminal 30, the setting unit 2g disconnects the detection unit 2b, and changes the imaging area of the home video camera 1 by remote control from the center terminal 30 so as to perform imaging. Control.

Specifically, the driving is such that the photographing magnification of the home video camera 1 is changed, or the lens is moved in the left, right, up and down directions to change the image pickup range. After such driving, the state of the set area is confirmed (presence or absence of an intruder, image acquisition at the time of intrusion). Then, after the confirmation is completed, a monitoring start instruction is issued from the center side terminal 30 to return to the monitoring state. Since the monitoring start instruction / monitoring end instruction can be performed in this manner, more detailed monitoring contents can be confirmed.

In order to provide a more full-fledged security device, an infrared video camera that can be used at night instead of the home video camera 1 is used, or a personal computer having the center terminal 30 installed in a crime prevention association. A network may be formed in a nearby area as a computer. As described above, the security device of the first embodiment can be configured to be inexpensive and simple.
