Description

  The present invention relates to a security camera system for recording camera images installed in a building, and more particularly to a security camera system for an elevator that records and reproduces accompanying detection and suspicious person behavior.

  In recent years, crimes in elevators in condominiums and condominiums are increasing, and in order to prevent such crimes, cameras are installed in the car and at the same time devices for recording images are being attached. In recent condominiums, devices with high security that cannot be entered without entering a PIN code or collating with an ID collation device at the time of admission are increasingly installed, restricting access to people other than residents It is supposed to be. However, although such crime prevention equipment has been introduced, it is difficult to completely prevent the intrusion of the suspicious person by bringing them together (when the resident checks and opens the door and enters the door together).

  For this reason, various proposals have been made for security camera systems for elevators aimed at suppressing crimes. For example, a system that restricts the use of an elevator by collating user iris information has been proposed (see, for example, Patent Document 1).

  There has also been proposed an apparatus that records an elevator operation state in an image recording device and searches for an image according to the elevator operation state (see, for example, Patent Document 2).

  Further, a proposal has been proposed in which face information is extracted from a camera image and a registration permission signal for a destination floor is generated (see, for example, Patent Document 3).

  However, all of the proposals that have been proposed in the past include means for restricting the use of elevators by authenticating the iris and face, but it is possible to detect a suspicious person who has not been registered in advance, There is no description about means for retrieving information or reproducing the movement of the suspicious person (from which floor and which floor got off) linked to the movement of the elevator when the suspicious person enters the building.

  The present invention has been made to solve the above-described problems. When a suspicious person is entered from a plurality of camera images installed in a building, the recording density of the camera image is increased and the monitoring center The purpose is to provide a security camera system that can record the operation history of the elevator at the same time, and can search for the suspicious person and grasp the behavior later.

  In the security camera system for an elevator according to the present invention, an elevator control device that controls the operation of the elevator, a monitoring center that remotely monitors the operation state of the elevator, a remote monitoring device that communicates with the monitoring center, An image recording means for recording video from a plurality of cameras and a user registered in advance from input images of the camera, provided with cameras installed at a plurality of locations and an image recording device for recording video from the cameras Suspicious person identification means that detects other persons as suspicious persons, and when a suspicious person enters the suspicious person is detected by the suspicious person identification means, the monitoring center issues a notification and records the operation information of the elevator used by the suspicious person Means.

  Further, in addition, a reproduction means for reproducing a trace of a suspicious person using an elevator based on the operation information recorded in the operation history recording means and the image information recorded in the image recording means is provided. Is.

  The suspicious person specifying means registers the detected suspicious person in the database, thereby enabling a person search later.

  Further, the image recording means increases the image recording density more than usual when the suspicious person specifying means detects the suspicious person.

  The operation history recording means includes the suspicious person's boarding and getting-off floors and time information as elevator operation information.

  According to the present invention, when entering a suspicious person is detected from a plurality of camera images installed in a building, the recording density of the camera images is increased, and at the same time, the monitoring center is notified and the operation history of the elevator is recorded at the same time. Since it is possible to grasp the search and behavior of the suspicious person later, the crime using the elevator can be prevented.

Embodiment 1 FIG.
A first embodiment of the present invention will be described with reference to FIG. Reference numeral 1 denotes an elevator control device that controls the operation of an elevator, 2 denotes an image recording device that records camera images installed at a plurality of locations in a building such as an apartment, 3 denotes an entrance of the apartment, etc., and 4 denotes an elevator car. Further, 3a is installed at the entrance 3, and the entrance camera installed at a position for identifying the face of the visitor, 4a is the in-car camera installed in the car, 4b is the landing camera 1 installed at the landing 1, Reference numeral 4 c denotes a hall camera 2 installed in the hall 2. The camera can be installed in other locations. Further, the elevator can be installed not only on one but also on a plurality of elevators. 5 is an image monitor connected to the image recording device 2 and displays camera images and reproduced images, 6 is a registration device for previously recording a face image of a resident of a building, and 7 is installed in a remote place and has a plurality of units. A monitoring center 8 for grasping elevator failure information and the like, 8 is a remote monitoring device for connecting the elevator control device 1 and the monitoring center 7 by communication. Of these, the image recording apparatus 2 will be described in more detail. 2a is an image recording means for recording a camera image. When a suspicious person is detected, the image recording density can be increased more than usual. 2b is a suspicious person specifying means for specifying a person other than the user registered in advance from the camera image, that is, a suspicious person. By registering in the database 2g, person search can be performed later. 2c is connected to a plurality of cameras 3a, 4a to 4c, and image selection means for selecting a plurality of camera images, 2d is notified to the monitoring center 7 when a suspicious person specifying means 2b detects the entrance of a suspicious person, Operation history recording means for simultaneously recording elevator operation information used by a suspicious person, 2e is an image display means for displaying an image on the image monitor 5, and 2f is elevator operation information and image recording recorded in the operation history recording means 2d. Based on the image information recorded in the means 2a, reproducing means for reproducing the trace that the suspicious person moved using the elevator, 2g is connected to the registration device 6, and records the face image of the resident in the building in advance. The database 2h is a communication means for communicating with the remote monitoring device 8.

  Next, the operation realized in the first embodiment will be described based on the flowchart of FIG. First, in step ST201, a camera image of the entrance camera 3a installed in the entrance 3 is input, and in step ST202, it is determined whether a person (suspicious person) other than a resident registered in advance is detected by the suspicious person specifying means 2b. If a suspicious person is detected, the image recording density by the image recording means 2a is increased from the normal level in step ST203. In order to efficiently accumulate the accumulated image data, for example, an image is normally recorded once every 2 seconds. However, when a suspicious person is detected, the image is recorded 30 times per second. Next, in step ST204, the suspicious person's face image is registered in the database 2g, the suspicious person's entrance information is recorded in step ST205, and the monitoring center 7 is notified in step ST206. Next, in step ST207, it is determined whether a person other than a resident who has been registered in advance is detected by the landing camera 4b installed in the landing 1, it is determined whether a passenger's boarding is detected in step ST208, and the boarding is detected. In step ST209, the boarding information of the suspicious person is recorded. Next, in step ST210, it is determined whether a person other than a resident who has been registered in advance is detected by the in-car camera 4a of the car 4, and if a suspicious person is detected, it is determined whether a passenger getting off is detected in step ST211. . If getting off is detected, the information on getting off the suspicious person is recorded in step ST212.

  Next, image information and elevator operation information recording means realized in the first embodiment will be described with reference to FIG. This information is a combination of image information from the camera and elevator operation information. In order from the left, the serial number information of the information and the time information are recorded. The suspicious person No. is obtained by sequentially storing the detected suspicious persons in the database 2g and assigning the numbers. The number of times of detection is a cumulative value of how many times the suspicious person who assigned each serial number has been detected in the past. Admission is set to 1 when entering. Unit No. sets the elevator unit number where the suspicious person got on. The boarding floor sets the floor where the suspicious person got on, and the getting-off floor sets the floor where the suspicious person got off. By managing information in this way, image information, operation information, and suspicious person information can be managed in a unified manner, and it is possible to easily cope with a person search later.

  Next, a procedure for searching for a suspicious person realized in the first embodiment will be described with reference to the flowchart of FIG. First, in step ST401, the database 2g is searched, and in step ST402, it is determined whether or not it matches the suspicious person database that has already been registered. If they match, the cumulative number of times detected so far in step ST403 is displayed on the monitor screen. In step ST404, based on the image information and the operation information of the elevator, the trace that the suspicious person has moved using the elevator is reproduced on the image monitor 5 by the reproducing means 2f.

  The image monitor 5 described here may be installed in a manager room in the building, or may be installed in a remote monitoring center 7. Further, the image recording apparatus 2 may be configured by a dedicated device or a general-purpose personal computer.
