Surveillance Camera Event-Triggered High-Quality Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance cameras require higher storage capacity to transmit high-quality images upon request, increasing costs and bandwidth usage.
Innovation Solution
A surveillance system that analyzes images to identify events and triggers higher-quality image capture locally, transmitting only when necessary, reducing storage demands on both the camera and server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cameras store and transmit high quality images upon request, then image quality for further examination is improved, but storage capacity requirements and costs increase
Solution Approach 1:
The system applies different quality levels to different portions of the surveillance data stream. Low-quality images are transmitted continuously for monitoring, while high-quality images are captured and transmitted only when events are detected, creating local quality variations based on operational needs
Solution Approach 2:
The image quality is made dynamic rather than static. The camera switches between low-quality continuous transmission and high-quality event-based transmission based on real-time conditions, allowing the system to adapt quality levels to actual surveillance requirements
2Measurement precision
If cameras continuously transmit high quality images, then image quality is improved, but bandwidth usage increases
Solution Approach 1:
Instead of continuous high-quality transmission, the system uses periodic low-quality transmission interspersed with event-triggered high-quality transmission. The analysis component periodically evaluates incoming low-quality images to determine when high-quality capture is necessary
Solution Approach 2:
The system extracts only the necessary high-quality images from the continuous stream based on event detection. Rather than transmitting all high-quality images, it takes out and transmits only those portions where events occur, reducing overall bandwidth consumption
3Measurement precision
If cameras have higher storage capacity, then ability to provide high quality images is improved, but camera costs increase
Solution Approach 1:
The camera performs partial high-quality capture rather than continuous high-quality capture. It captures high-quality images only for detected events, using excessive action only when necessary rather than continuously, thereby reducing storage requirements while maintaining the ability to provide high-quality images when needed

AI summary
Certain aspects of the present disclosure may include methods, systems, and non-transitory computer readable media for receiving a first plurality of images from a first camera, analyzing the first plurality of images to identify an event, transmitting an indication signal to the first camera indicating the identifying of the event, and receiving a second plurality of images from the first camera in response to the first camera receiving the indication signal, the second plurality of images occupying more storage space than the first plurality of images.
