JP6151891B2 - Crime prevention system - Google Patents

Description

  The present invention relates to a technique for detecting a suspicious person with a security camera and ensuring the safety of a site before a crime is committed.

At present, many crime prevention systems are widely adopted not only in office buildings and condominiums, but also in private homes.
There are various types of security systems, such as devices that threaten intruders with light and sound using sensors that react to intruders, and systems provided by security companies that allow security guards to rush in the event of an emergency.

  However, in order to respond to the improvement of the crime prevention system, techniques such as intrusion into a residence have become more sophisticated, and it is difficult to say that crimes are effectively prevented. This is clear from recent crimes and clearance rates.

  In this regard, for example, Patent Document 1 relates to a security system including a sensor terminal that detects an intruder into a monitoring area around a building, and a monitoring terminal that acquires detection information from the sensor terminal and executes alarm processing. When an intruder is detected, it is determined whether or not the user can confirm whether or not the report is necessary. If the confirmation is not possible, the detection information is transmitted to the monitoring center, and if the confirmation is possible, the occurrence of the intruder is notified. A system has been proposed that prompts confirmation of the necessity of reporting and transmits detection information to a monitoring center when a reporting operation is performed.
