Description

Alarm detecting system with image and sound processing device {Event detecting system with image and sound}

In safety-vulnerable areas such as pedestrian crossings and schools, there are many cases where it is difficult to determine the situation even when there are no witnesses or witnesses when an emergency or warning situation occurs due to a traffic accident, illness or crime. Therefore, security CCTV and DVR system is installed in safety vulnerable areas such as pedestrian crossings and schools, and it is used as follow-up data by monitoring or recording the emergency or alarm situation at all times.

However, CCTV and DVR systems for security vulnerable areas such as pedestrian crossings and schools are not immediately able to respond to emergency or alarm situations without constant monitoring, and simply use the recorded data afterwards. In the event of an emergency or alarm situation, there will be a delay in delivering to the appropriate alarm delivery station (eg fire station, police station, school, hospital, etc.) to take appropriate action.

In general, the present invention detects abnormal movements and sounds and generates alarms through CCTV cameras and microphones installed in pedestrian traffic lights. At the same time, the alarm, video and sound are delivered to the promised object so that they can respond quickly to an emergency.

In addition, since CCTV and DVR systems for security vulnerable areas such as general pedestrian crossings and schools are simply monitoring or storing images, the activities of unspecified persons are publicly exposed and recorded regardless of their intention, which may cause privacy to be infringed. By minimizing the possibility of invasion of privacy by not only storing video and sound but also inevitable alarm situation, it raises the reliability and density of video and sound information and dramatically reduces the amount of unnecessary information. It can dramatically increase the utilization of video storage device, which accounts for a large part of the cost of security CCTV and DVR system for security vulnerable areas such as school and school. In addition, by recording video and sound together, the utilization of information can be greatly increased.

In safety-vulnerable areas such as pedestrian crossings and schools, it is often difficult to judge the situation even when there are no witnesses or witnesses when an emergency or alarm situation occurs due to a traffic accident, illness or crime. Always monitor or record an emergency or alarm situation and use it as a follow-up data.

CCTV and DVR systems for security vulnerable areas such as general pedestrian crossings and schools around the world simply monitor or store the images, so the activities of unspecified persons are publicly exposed and recorded regardless of their will. Results in storage.

The problem to be solved in the present invention is to build a system to quickly cope with the alarm situation occurring in a safety vulnerable area, such as crosswalks, school surroundings.

In addition, the actions of unspecified people of CCTV and DVR systems for security vulnerable areas such as general pedestrian crossings and schools around the school are openly exposed and recorded regardless of their intention, and the system is set up to solve the problem of privacy infringement.

It also aims to reduce unnecessary information, which accounts for a large part of the cost of CCTV and DVR systems for security vulnerable areas such as general crosswalks and schools.

In addition, CCTV and DVR systems for security vulnerable areas such as general pedestrian crossings and schools are lacking in information, such as sound, so that the utilization of information is greatly reduced.

The present invention is equipped with a device for monitoring the movement and sound of the object through the CCTV cameras and microphones installed in vulnerable areas such as pedestrian crossing, school surroundings and detecting whether the movement and sound of pedestrians are abnormal, and when the abnormal movement is detected, And at the same time deliver the alarm, video and sound to the promised object.

In addition, CCTV and DVR systems for security vulnerable areas such as general pedestrian crossings and schools are exposed and recorded in public regardless of their intentions, and invade privacy. The system so that it is stored.

In addition, the system configured to store the video and sound only in the unavoidable alarm situation of the present invention reduces unnecessary information that occupies a significant portion of the cost of CCTV and DVR system for security vulnerable areas, such as general crosswalk, school surroundings.

In addition, the system is equipped with a device for analyzing sound in addition to the image, further increasing the utilization of information.

In the present invention, images and sounds are stored only in an inevitable alarm situation, so that public activities are exposed regardless of the intention of the person, thereby minimizing the possibility of invasion of privacy, and attaining the purpose of coping with emergencies, preventing crime, and securing after evidence. In addition, by increasing the reliability and density of video information, the amount of unnecessary information can be drastically reduced, which can significantly increase the utilization of video storage devices, which account for a large part of the costs of existing security CCTV and DVR systems. This is an improved invention in the use of information compared to the existing CCTV and DVR system for crosswalk security.

In addition, by classifying the image according to the type of alarm, designate the alarm delivery point (e.g. home, fire station, police station, school, hospital, etc.) and simultaneously transmit the alarm signal and its video information (wired communication, wireless communication, network, internet, etc.). ), It provides social and economic effects by preventing the rapid response and unnecessary dispatch by providing the judgment ground of the relevant institution. In addition, by recording video and sound together, the utilization of information can be greatly increased.
