Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention detects a suspicious person or the like entering a facility such as a parking lot or a warehouse, and turns on an illuminator when the suspicious person enters at night. The present invention relates to an intruder management apparatus that uses a video camera for shooting for a predetermined period of time, records this video with a recording device, identifies a suspicious individual, and uses it for crime prevention.

[0002]

2. Description of the Related Art Various devices have been developed to detect a suspicious person or the like when they enter in various facilities, and to further photograph and record the information to identify the suspicious person and use it for crime prevention. Some are commercially available.

Some examples thereof are disclosed in, for example,
Security alarm system described in JP-A-223276, surveillance system described in JP-A-7-37175, JP-A-9-37175
There is a video camera system and an automatic tracking method thereof described in JP-A-102948.

In the security alarm system described in Japanese Patent Application Laid-Open No. Hei 6-223276, when an alarm signal is output from a signal processing unit, a video signal from a TV camera is transmitted to a receiver for a predetermined time, which is at night. In such a case, the light is turned on and a good image can be taken.

[0005] The monitoring system described in Japanese Patent Application Laid-Open No. 7-37175 includes a lighting device, a television camera, an intruder detection device,
Equipped with a VTR, video monitor, etc., when an intruder is detected, it is photographed by a television camera and displayed on a video monitor, and this image is photographed by a VTR. If this is nighttime, the lighting device is turned on. It is composed.

[0006]

As described above, there are various prior arts, and among them, Japanese Patent Application Laid-Open No. 6-223276.
The security alarm system described in Japanese Patent Application Laid-Open Publication No. H10-27095 is configured so that when an intruder is detected, an alarm signal is output and a video signal is transmitted to a receiver, so that warehouses, stores, buildings, and the like become unmanned at night. Is suitable for remote monitoring of the presence or absence of intruders and the appearance of intruders.However, if this system is installed in facilities such as parking lots where people can enter and exit at night, for example, The monitoring becomes very troublesome.

Further, the surveillance system described in JP-A-7-37175, the video camera system described in JP-A-9-102948, and the automatic tracking method thereof are configured to record an image of an intruder on a video deck. But
For example, if this system is introduced into a facility such as a multistory parking lot where people enter and exit even at night, the permissible recording time of the video tape will end immediately, and it will be necessary to frequently change the video tape. In other words, these prior art systems are systems that assume that there is a supervisor or a security guard, considering that the monitor is permanently installed. Therefore, it is not suitable as an unmanned monitoring device.

As a countermeasure, there is a method of taking a frame at a normal speed so that one video tape can be recorded as long as possible, for example, shooting for 6 seconds, stopping for 12 seconds, and then shooting for 6 seconds. By repeating the shooting, the elapsed time of 24 hours can be recorded on one videotape, and if this interval is further shortened, the elapsed time of about 72 hours can be recorded. Since it is necessary to incorporate an inverter device and a deceleration drive device for controlling the speed, there is a problem that the manufacturing cost of the entire device becomes high.

The inventor of the present invention has found that prior art apparatuses and systems having the above-mentioned problems are not suitable for setting up facilities such as unmanned parking lots, and include large and medium-sized unmanned parking lots. We tried to develop equipment that can be installed in various facilities. As a result of intensive studies and trials of several prototypes, a novel intruder management device was finally completed.

According to the present invention, which has been completed through such a process, when a person enters or exits the facility, the illuminator is turned on when it is nighttime, and an intruder is illuminated by a video camera for a predetermined time. It is possible to take a picture and record it with a recording device. Since the photographing time is limited to a predetermined time from when a person enters and exits, it is recorded on a single video cassette tape etc. for a long time And the need for a guard is eliminated, and the equipment is small, so that it can be installed in an unmanned facility with some traffic at night, such as a large or medium-sized parking lot. It is an object of the present invention to provide an intruder management device that is useful for taking out a film or the like recorded after a crime has occurred and reproducing the situation or identifying a criminal.

[0011]

The intruder management device according to the present invention proposed to achieve the above object has a sensor for detecting an intruder entering or exiting an intruder detection area, and the sensor for detecting intrusion of the intruder. When an intruder is detected at night or the like, an illuminator that lights up toward the area, a video camera that captures an image of the area when the sensor detects an intruder, and a video camera that captures the image by the video camera. It is characterized by comprising a timer circuit for setting a time, a recording device for recording a shot video, and a signal processing unit for controlling a detection signal between these devices.

The above configuration is a basic configuration of the present invention. As a sensor for detecting the presence or absence of an intruder, a far-infrared sensor that catches far-infrared rays emitted from a human body, an image sensor for identifying a human body, or a sound sensor One or more of these are used.

The illuminator is always directed to the detection area. The illuminator is linked to a timer or an illuminance sensor, and receives a detection signal from the sensor at night or when the detection area is always dim. Lights for a predetermined time.

The video camera used in the present invention is not an expensive camera such as a conventional surveillance system, but a small one having a waterproof structure. In addition, it is desirable to use a digital video camera that can capture high-quality images among video cameras, can be divided and recorded on a recording device, and can easily perform post-processing. In the present invention, the video camera is always pointed at the detection area at all times, and operates in response to a detection signal from the sensor to perform photographing for a predetermined time similarly to the illuminator.

The time when a suspicious person breaks into a parking lot and damages or steals a car is quick, and most of the time is within 10 minutes. Therefore, for example, one hour is set from when a person enters or leaves the parking lot. There may be a case where shooting is continued during that time. Therefore, the shooting time can be adjusted by a timer circuit.

A video deck used as a recording device for recording a photographed video has a built-in small sequencer, and a timer in the sequencer sets a timer from 24 hours to 7 hours.
A configuration was adopted in which shooting corresponding to the elapsed time up to two hours could be recorded in frames, and the time zone that can be recorded on one video tape was extended.

By displaying the date, hour, minute, and second of each recording on the recorded videotape, the incident site and time can be specified. Help.

Further, a timer circuit is provided as a video deck for counting each time a frame is recorded in this manner, and when the end of the video tape is sensed, the video tape is automatically rewound and endlessly recorded. Use of a recording device that does not require tape replacement and the frame recording is performed for a long period of time, so that there is almost no delay in checking the tape image after the incident.

In the present invention, the recording apparatus is not limited to the above-described video deck, and another recording apparatus may be used. One example is a personal computer. In this case, the recording medium is an FD or CD in addition to the memory in the personal computer. In addition, a small-sized recording device recorded on a dedicated memory chip may be used.

With this configuration, the recording time can be lengthened, the required time zone can be reproduced instantaneously, and not only is the whole device small and compact, but also the image can be monitored by wire or wirelessly. It can be sent to a room. Correspondingly, the intruder management device according to the present invention includes a device provided with a communication function. In this way, remote monitoring and emergency notification can be performed. In this way, there is an advantage that the management of each facility can be centrally managed at one place.

The inventor of the present invention does not include a monitor since the inventor has developed this intruder management apparatus in a large and medium-sized unmanned parking lot. However, the intruder management device according to the present invention is not limited to such a use, and also supports monitoring of a warehouse or a store from a monitoring room or the like. In such a case, a monitor may be connected. No problem. In order to cope with such a case, a recording device and a monitor connected by a long signal line are also included in the present invention.

In the above arrangement, when an intruder enters or exits the intruder detection area, the situation is photographed by a video camera. Even in the intruder detection area, the distance between the camera and the intruder is determined. If there is a certain distance, the intruder may appear small, and the face or the like may be difficult to recognize.

In order to cope with such a case, according to the present invention, when an intruder enters or exits, the inside of the intruder detection area is photographed by a video camera as described above, and a fixed time is taken from this intrusion time. Time, eg 5
When more than one minute has elapsed, a configuration is also added in which the intruder is specified, a large image is taken with another camera, and this image is recorded with a recording device. As a method for taking a large image, there are a case where a convex lens having a long focal length is used and a case where a zoom mechanism is provided. Either one may be adopted in the present invention. With this configuration, it is easy to identify the intruder, and it is sufficiently useful as evidence later.

In the present invention, in addition to the above basic configuration, an intruder is tracked by a plurality of sensors, is photographed by a plurality of cameras, and this image is recorded by a recording device. To be monitored and recorded on video. As a technique used as this tracking method, a servo mechanism using a motor so that a plurality of sensors provided at predetermined intervals and another camera can be controlled in the X-axis and Y-axis directions, respectively. The center of these sensors captures the far-infrared rays emitted by the human body, and follows the movement of the far-infrared rays, and calculates the exact position of the movement amount by triangulation. There is a technique for causing a plurality of cameras to follow based on a calculated value.

[0025] In this manner, the intruder can be photographed following the intruder's action, so that it is easier to identify the intruder, and the entire crime can be photographed. For this reason, it becomes an extremely valuable evidence as later evidence.

The above configuration is such that when a person enters or exits the detection area irrespective of day or night, the photographing and recording are performed when the person is detected. The present invention also provides a video camera in which shooting and recording are always performed by a video camera, and in the nighttime when there are few people coming and going, the shooting and recording are performed only when it is detected that a person enters or leaves the detection area. To be included.
