Integrated CCTV Abnormality Detection via Sensor Matrix
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional CCTV systems have limited control range due to blind spots and lack of sound detection capabilities, and emergency alert systems are not functional during emergencies unless manually operated.
Innovation Solution
An integrated monitoring CCTV system that collects video and sound information using multiple microphones and cameras, generates monitoring information with location and direction data, and uses an abnormality detection apparatus to determine abnormal situations like explosions or flying objects, broadcasting warnings when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional CCTV is equipped with only video recording function, then the device complexity is low, but the measurement precision and detection capability are limited due to blind spots
Solution Approach 1:
The patent combines video recording, sound detection, and sensor information collection into a single integrated monitoring CCTV system. Multiple microphones are incorporated to enable omnidirectional sound detection, and various sensors are integrated to detect explosions, flying objects, and other abnormalities, thereby improving detection capability without requiring separate devices
Solution Approach 2:
The monitoring CCTV is designed to perform multiple functions simultaneously: video recording, sound source detection and localization, explosion detection, flying object detection, and environmental monitoring. This multi-functional approach eliminates blind spots and improves measurement precision while maintaining a single device structure
2Reliability
If emergency bell device is manually operated, then the device complexity is low, but the reliability is poor because it may not operate normally in emergency situations
Solution Approach 1:
The system enables automatic emergency response through abnormality detection. When the integrated monitoring CCTV detects abnormal sounds, explosions, or flying objects, it automatically generates alarm signals and broadcasts warnings without requiring manual operation. The system serves itself by detecting abnormalities and triggering appropriate responses autonomously
Solution Approach 2:
The system continuously monitors the environment through multiple sensors and microphones, provides feedback when abnormalities are detected, and automatically activates alarm functions. This closed-loop feedback mechanism ensures reliable operation during emergencies by eliminating human response delays
3Area of stationary object
If single CCTV is used for monitoring, then the device complexity is low, but the area of coverage is limited due to blind spots
Solution Approach 1:
The patent extends monitoring from two-dimensional video coverage to three-dimensional spatial awareness by incorporating omnidirectional sound detection and sensor data. Multiple microphones arranged in specific configurations enable detection of sound sources from all directions, adding a dimensional aspect to the monitoring coverage and eliminating blind spots
Data Source
AI summary
Disclosed herein are an integrated monitoring CCTV, an abnormality detection apparatus, and a method for operating the apparatus. The abnormality detection apparatus includes a monitoring information collection unit for collecting monitoring information that includes location information, sound information and time information of a monitoring area from at least one integrated monitoring CCTV including multiple microphones; and an abnormal sound determination unit for determining whether an abnormality has occurred in the monitoring area, based on the sound information of the monitoring area, wherein the abnormality detection apparatus further comprises an explosion occurrence determination unit for, based on information about installation locations and installation directions of multiple integrated monitoring CCTVs transmitted from the multiple integrated monitoring CCTVs, generating a sensor matrix map for the multiple integrated monitoring CCTVs and calculating a location of occurrence of an abnormal sound based on the sensor matrix map when the abnormal sound occurs.
