Description

  The present invention relates to a video monitoring system, and more particularly to a video monitoring system that notifies an external device of an abnormal state and provides support for eliminating the abnormal state.

  Conventionally, in order to prevent crime, a camera is installed at a monitored site and an image captured by the camera is monitored from a remote place, and a hard disk drive (Hard Disk Drive: HDD, hereinafter referred to as HDD) provided in a video recording apparatus. There is a system in which a video is recorded on a recording medium, and the past situation is confirmed by playing back the recorded video, which is used as a clue for solving the case.

  As the above system, for example, when an abnormality occurs, a system for detecting an abnormal state and notifying the outside and recording a video at a high definition / high recording rate has been proposed (for example, Patent Documents). 1).

  In addition, a monitoring system has been proposed in which, when an abnormality occurs, a mail indicating the occurrence of the abnormality is transmitted to a remote place (see, for example, Patent Document 2).

WO06 / 092854 JP 2002-252715 A

  The system described in Patent Document 1 is realized by including a monitored site where a camera is installed and a monitoring center that monitors video captured by the camera. In such a system, a supervisor is assigned to the monitoring center. Since the burden of resident expenses is incurred, it is difficult to realize by applying it to a small-scale store or the like that cannot spend a lot of expenses to operate the system.

  Further, in the monitoring system described in Patent Document 2, an abnormal state is notified by sending an image captured by the monitoring camera by e-mail, so that there is no cost burden to make the monitoring person resident in the monitoring center. A monitoring system can be realized at low cost. In addition, in the monitoring system described in Patent Document 2, only the fact that an abnormality has occurred is notified, and in order to know the current state, a separate phone call is made to the person staying at the monitored site. Means such as confirmation are necessary. However, for example, assuming a situation where a store clerk faces a burglary in a store, it can be easily guessed that even if a call is made to the store after receiving a notification of the occurrence of an abnormality, the store clerk may not be in a state that can respond .

  As described above, conventionally, when an abnormality occurs, the main focus is on notifying the outside, and the purpose is not to eliminate the abnormal state. However, in the above abnormal state, it is desirable that, for example, a store clerk can easily make a rescue request to the outside. In addition, when an abnormal state occurs, a situation where both the person at the monitored site (for example, the store clerk) and the person who has received the notification of the abnormal state cannot be calmly determined and dealt with is assumed. In order to learn how to deal with such situations, simulation training, etc. may be conducted, but in actual situations, the assumed treatment method may be forgotten and countermeasures are required. Yes.

  The present invention has been made to solve these problems, and it is an object of the present invention to provide a video surveillance system capable of notifying the outside of an abnormal state and providing support for eliminating the abnormal state. And
