Security Monitoring with Radio Location-Guided Camera Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security monitoring systems with multiple video cameras experience delays in transmitting critical video data to a remote monitoring station due to limited bandwidth and contention issues, leading to delayed decision-making and potential life-threatening situations.
Innovation Solution
Implement a radio-based location sensing arrangement to detect human presence and location within premises, using perturbations of radio signals to guide the remote monitoring station on which camera's data to prioritize, thereby reducing the volume of data transfer and enabling faster decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple video cameras transmit video data simultaneously over limited bandwidth channels, then complete video data from all cameras is eventually received, but critical video data is received with significant delay
Solution Approach 1:
The system performs preliminary actions by detecting motion events and identifying which cameras have captured critical video data before initiating the data transmission process. This allows the monitoring station to prioritize and request video data from specific cameras that captured relevant events, rather than waiting for all cameras to transmit their data in sequence.
Solution Approach 2:
The central unit acts as an intermediary between the video cameras and the remote monitoring station. It receives video data from multiple cameras, identifies which cameras captured critical events based on motion detection, and selectively forwards only the relevant video data to the monitoring station, thereby reducing transmission delays and bandwidth requirements.
2Reliability
If video data from multiple triggered cameras is transmitted over limited bandwidth channels, then all video data is eventually supplied, but the supply process takes several minutes
Solution Approach 1:
The system extracts and identifies only the critical video data from multiple cameras that contains relevant event information. By using motion detection and event correlation, the system determines which specific camera recordings are necessary for the monitoring station, extracting only those data streams and excluding redundant footage, thereby significantly reducing transmission time and bandwidth requirements.
3Reliability
If the central unit supplies video data from multiple triggered cameras to the remote monitoring station, then complete surveillance coverage is provided, but decision-making is delayed due to reception time
Solution Approach 1:
The system performs preliminary identification of critical video data by correlating motion detection events with camera locations before transmission. This preliminary action allows the monitoring station to receive and act on critical surveillance information immediately, while complete surveillance coverage is maintained through selective data transmission from the identified critical cameras.
