  The present invention relates to a surveillance camera system such as a CCTV system.

In surveillance camera systems such as CCTV (Closed Circuit Tele-Vision) systems, in order to perform surveillance to prevent theft, infrared sensors and the like are installed in the monitored area to link the sensors. However, theft of the camera device itself to be monitored is taken as a theft countermeasure by adopting an anti-theft measure by installing a special bolt or the like, or adopting a lock mechanism by a special lock.
In addition, when the installed bolts are removed or the lock mechanism is released, the camera device main body's danger information (alarm) due to the camera housing door being opened, etc. It has also been implemented to issue an alarm and notify the monitoring center side (see, for example, Patent Document 1).
JP 2000-67332 A

In surveillance camera systems such as CCTV devices, surveillance camera devices are often installed unattended in remote locations. Even if the monitoring center knows that, even if a staff member goes to the installation location of the camera device where the abnormality has occurred, there is a problem that theft cannot be prevented because it is not in time.
An object of the present invention is to provide a surveillance camera system that solves the above-described problems and includes prevention of theft of the camera device itself, which is a device originally intended for monitoring.

  In order to achieve the above object, the monitoring system of the present invention uses the following means. That is, a sensor for detecting door opening is installed on the door of the camera housing (camera case) and the door of the control panel, and alarm information is output when the door is opened. A control signal is transmitted from the control device to another camera device capable of confirming the control device and the alarm occurrence location based on the alarm information, and the alarm occurrence location is photographed. The sensor is, for example, a contact sensor, and detects that the contact has been released when the door is opened.

  That is, the monitoring system of the present invention includes a camera device that captures an image of the area to be monitored, a camera housing that houses the camera device, a control panel, and a monitoring center that is coupled to the control panel via a network for monitoring. In a surveillance camera system in which a control panel transmits and receives data to and from a monitoring center via a network and controls a camera device and a camera housing, the camera housing and the control panel confirm that the door is opened at each door. When the sensor detects that the door has been opened, alarm information is transmitted from the control panel to the monitoring center via the network.

Preferably, the monitoring center of the monitoring system of the present invention has a database that stores information about the camera device. When alarm information is received, the monitoring center acquires information about the corresponding database, and based on the acquired information. Information related to the corresponding camera device is transmitted.
Preferably, the related information is preset position information.

  According to the present invention, it is possible to prevent the camera device itself from being stolen even when a special installation or lock mechanism is employed. Even when 24-hour monitoring is not performed on the operation terminal, an abnormality can be notified by mail to the home PC or mobile phone.

  An embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration of a monitoring system according to an embodiment of the present invention. 10-1, 10-2, ..., 10-n is a camera device, 11-1, 11-2, ..., 11-n is a camera device 10-1, 10-2, ..., 10 -n camera housings, 12-1, 12-2,..., 12-n are installation bases for mounting the camera housings 11-1, 11-2,. -1, 20-2,..., 20-n is a control panel, 3 is a network, 4 is a control device, 5 is a recording device, and 6 is a terminal device.

The terminal device 6 is, for example, a PC (Personal Computer) installed in a general household, and there is an unspecified number. In the following, camera devices 10-1, 10-2,..., 10-n are camera devices 10, camera housings 11-1, 11-2,..., 11-n are camera housings 11, installation bases 12- 1, 12-2,..., 12-n are collectively referred to as installation base 12, and control panels 20-1, 20-2,.

  In FIG. 1, contact sensors (not shown) are respectively installed on the camera housing 11 housing the camera device 10 and the door of the control panel 20 on which the camera housing 11 is mounted. When the perpetrator operates to tamper with the camera device 10 or the control panel 20 or opens their doors to cause external actions such as harm or theft, the contact sensor detects that the door has been opened. Then, alarm information notifying that the door has been opened is issued and transmitted to the control device 4 via the network 3. The contact sensors of the camera housing 11 and the control panel 20 are both provided with a notification output unit on the control panel 20, and the control panel 20 outputs alarm information predetermined for the corresponding sensor according to detection information from the sensor. To do.

  When the control device 4 receives the alarm information, the control device 4 refers to the data registered in advance from the received alarm information, identifies the camera device 10-1 having the reported contact sensor, Acquire information about the camera device 10-2 and its preset positions that can photograph the surrounding area. The preset position information is, for example, information such as zoom magnification, pan angle, tilt angle, lens aperture condition, or frame rate.

  Next, the control device 4 transmits a control signal corresponding to the preset position information to the camera device 10-2 via the network 3. The control panel 20-2 that receives the control signal from the control device 4 controls the installation base 12-2 and the camera device 10-2, changes the viewing angle of the camera device 10-2, and issues alarm information. The camera device 10-1 and its surroundings are imaged, and the captured images are output to the control panel 20. The control panel 20 converts the input video to a data format that can be transmitted to the network 3 and sends it to the network 3. In addition, it may be sent after being compressed into MPEG (Moving Picture Experts Group) format or the like.

  As described above, for the camera device that issued the alarm information, the camera device and the camera device that captures the periphery of the camera device are determined in advance, and the preset position is also determined in advance and is attached to the control device 4. (Or built-in) is recorded in the memory. The preset positions do not need to be fixed, and a plurality of positions may be imaged at predetermined time intervals, or the target camera device and its surroundings may be imaged while turning at a predetermined speed. Also good.

The control device 4 receives the video from the camera device 10-2 sent via the network 3, converts the received data into a displayable format, and displays it on the display device 41 coupled to the control device 4. The camera device 10-1 that issued the alarm information and the surrounding video are displayed.
The display device 41 is attached to the control device 4 and may be installed in the vicinity thereof, or may be installed in a remote place.

  In addition, for example, a recording device 5 is provided, which is directly coupled to the control device 4 or coupled via the network 3, and images of the camera device 10-2 and the camera device 10-1 that has issued an alarm are displayed. It may be recorded, or video captured by another camera device 10 may be recorded. (In this case, the recording device 5 directly records the video from each camera device 10 via the network 3). At that time, alarm information may be recorded in addition to video recording. In addition to time information such as the acquired time (date and time), the alarm information and video may include information on sensors other than the door sensor and status information on the camera device, the installation stand, and the control panel.

  Further, the control device 4 or the recording device 5 can also send an alarm mail to a preset address, and notifies the home PC 6 or mobile phone of an abnormality on the camera device side.

  According to the above embodiment, even when a special installation structure or a lock mechanism is adopted, an alarm is generated when danger information (alarm) is generated for the camera device that originally monitors each target area. As the other camera devices monitor the camera device, the camera devices can monitor each other to prevent theft of the camera device itself or to determine the theft crime.

Even when 24-hour monitoring is not performed on the operation terminal, an abnormality can be notified by mail to a home PC or mobile phone, so that the abnormality can be detected quickly.
