Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security camera systems for crime prevention require multiple cameras and manual operation, leading to high costs, limited coverage, and inefficiencies in responding to incidents, especially at night, due to their narrow sensing distance and need for manual control.
Innovation Solution
A radar security camera system that uses built-in radar sensors to detect targets 360°, determine if they are persons or vehicles, and automatically track them based on movement direction and priority, allowing for continuous monitoring and alert generation without the need for multiple cameras or manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple conventional security cameras are installed to cover 360° range, then monitoring coverage is improved, but system complexity and cost increase significantly
Solution Approach 1:
The patent combines radar and optical camera into a single integrated security monitoring device. The radar unit and camera unit share a common housing and control system, merging detection and imaging functions into one device that provides 360° coverage through rotational capability, eliminating the need for multiple separate cameras
Solution Approach 2:
The integrated security device performs multiple functions: radar-based target detection, optical imaging, target tracking, and abnormal behavior analysis. A single device replaces what previously required multiple specialized cameras, providing both wide-area surveillance and detailed imaging capabilities
2Loss of energy
If manual monitoring of security cameras is used, then operational cost is reduced, but response time to incidents increases
Solution Approach 1:
The system implements automatic feedback mechanisms where the radar continuously monitors for targets and the control unit analyzes camera images for abnormal signs. When abnormalities are detected, the system automatically generates alerts and notifications, creating a closed-loop feedback system that eliminates the need for continuous manual monitoring while enabling immediate response to incidents
Solution Approach 2:
The security system performs self-monitoring and self-analysis through integrated radar detection and AI-based image analysis. The control unit automatically processes video feeds, detects abnormal behaviors, and triggers alerts without human intervention, making the system self-sufficient in detecting and responding to security threats
3Area of stationary object
If 360° camera is used for wide coverage, then monitoring area is improved, but sensing distance becomes very narrow
Solution Approach 1:
The system segments the monitoring function into two complementary components: radar for long-range target detection and camera for short-range detailed imaging. The radar detects targets at distances of 100 meters or more, while the camera captures detailed images of targets within closer range, with the rotational mechanism allowing the camera to be positioned optimally for each detected target
4Reliability
If conventional security camera system is implemented, then basic monitoring is achieved, but intelligent control and automatic response are lacking
Solution Approach 1:
The patent replaces manual mechanical monitoring with automated electronic detection and analysis systems. The radar provides automated target detection, the control unit performs automated image analysis for abnormal signs, and the system generates automated alerts, substituting human-operated mechanical systems with intelligent automated systems that provide both reliable monitoring and intelligent control
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides comprehensive 360° coverage, reduces operational costs, and enables immediate response to incidents by automatically tracking and recording abnormal signs, enhancing security without the limitations of traditional camera systems.
Implementation Method 1
transmitting a radar signal in a coverage covering 360° by using two radar sensors each covering 180°, receiving the radar signal reflected from a target existing within the coverage
Data Source
AI summary
An intelligent control method and system using a radar security camera are disclosed, wherein a target is detected by 360° radar sensing regardless of the rotation radius of a camera by using the security camera having a built-in radar, and the camera is enabled to track the target according to the moving direction and specific signs of the target after the target is identified as a person and a vehicle sequentially according to a decision priority order.
