Fixed and Temporary Cameras for Adaptive Blind-Spot Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fixed cameras in surveillance systems often fail to capture abnormal events due to dead angles and cost limitations, leading to incomplete coverage and privacy concerns, making it difficult for security officers to understand incidents fully.
Innovation Solution
A surveillance system incorporating a fixed camera and temporary cameras, with a control means to extend coverage by deploying and adjusting temporary cameras based on sensor data from both fixed and temporary cameras, using ad hoc networks for data relay and automatic registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If fixed cameras are used for routine surveillance, then cost is reduced and installation is simple, but coverage is limited due to dead angles and cannot capture abnormal events in blind spots
Solution Approach 1:
The surveillance system is segmented into fixed cameras for routine monitoring and temporary cameras for abnormal event capture. The temporary cameras are deployed only when needed based on sensor detection, dividing the surveillance function into static and dynamic components that address different coverage requirements independently
Solution Approach 2:
The system transitions from a static fixed camera configuration to a dynamic system where temporary cameras are deployed and positioned based on detected abnormal events. The temporary cameras can be moved to optimal positions using sensors and control mechanisms, allowing the coverage area to adapt dynamically to incident locations
2Area of stationary object
If more fixed cameras are installed to eliminate dead angles, then coverage is improved, but cost increases and privacy concerns arise
Solution Approach 1:
The system uses sensor data from the fixed cameras and environmental sensors to automatically determine where temporary cameras should be deployed. The system self-manages the deployment decision-making process, eliminating the need for manual analysis and reducing the number of permanent cameras required
Solution Approach 2:
Temporary cameras serve multiple functions: they capture abnormal events, provide additional coverage in blind spots, and can be redeployed to different locations based on varying incident patterns. This multi-functionality reduces the need for dedicated fixed cameras in every potential blind spot
3Area of stationary object
If temporary cameras are deployed to extend coverage, then surveillance coverage is improved, but deployment complexity and sensor data processing requirements increase
Solution Approach 1:
Manual deployment and positioning of temporary cameras is replaced with automated sensor-based systems. Sensors detect abnormal events and automatically trigger the deployment and positioning of temporary cameras, eliminating manual intervention and simplifying operation
Solution Approach 2:
Sensors act as intermediaries between the fixed camera system and temporary cameras. The sensors detect abnormal events and transmit data to the control system, which then activates temporary cameras at appropriate locations, mediating the complex coordination between detection and deployment

AI summary
A surveillance system including a fixed camera and one or more temporary cameras and a control means coupled to the fixed camera and the one or more temporary cameras is disclosed. The control means is configured to extend coverage of the fixed camera using the one or more temporary cameras coupled to the fixed camera. Each of the one or more temporary cameras includes one or more sensors and is configured to be deployed and adjusted based on sensor data obtained from the one or more sensors of the one or more temporary cameras and from one or more fixed camera sensors co-located with the fixed camera.
