Solution Overview
Problem
Existing image surveillance systems face challenges in providing cost-effective visual surveillance and reporting, especially in areas where broadband Internet connections are not available or complex to configure, and they often rely on expensive network connections for transmitting live or recorded video.
Innovation Solution
A monitoring system that includes a camera unit capable of capturing still images, a gateway for communication using short-range wireless protocols, and a remote monitoring server, which analyzes images for relevant activity and selectively transmits only necessary data over expensive network connections, using techniques like differential image analysis and user-defined rules to manage data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If live or recorded video is transmitted over network connections, then visual surveillance capability is improved, but data transmission cost increases
Solution Approach 1:
The patent extracts only the essential information from video streams by detecting motion events and capturing only still images at critical moments rather than transmitting continuous video. The system extracts motion detection data from video streams and uses this to trigger selective image capture, thereby reducing data transmission volume while maintaining surveillance effectiveness.
Solution Approach 2:
The system performs partial action by capturing only still images rather than continuous video, and only when motion is detected. This selective approach captures the essential surveillance information without the excessive data transmission cost of continuous video streaming, achieving cost-effective visual surveillance.
2Productivity
If continuous video streaming is used, then real-time monitoring is improved, but network bandwidth consumption increases
Solution Approach 1:
The system uses periodic motion detection to trigger image capture only when necessary, rather than continuous streaming. The camera captures still images periodically based on motion sensor activation, maintaining real-time monitoring capability while dramatically reducing network bandwidth consumption compared to continuous video transmission.
Solution Approach 2:
The patent extracts motion detection information from continuous video streams and uses this extracted data to trigger selective image capture. This extraction approach allows the system to maintain real-time awareness of events while transmitting only essential image data rather than continuous video streams.
3Loss of time
If image analysis is performed locally at camera unit, then response time is improved, but processing power requirements increase
Solution Approach 1:
The patent segments the processing function between the camera unit and remote server. Simple motion detection and image capture decisions are made locally at the camera unit, while complex image analysis and event verification are performed remotely at the server. This segmentation reduces the processing power requirements at the camera unit while maintaining fast local response time for motion detection.

Data Source
AI summary
Image surveillance and reporting technology, in which an event that is indicative of potential physical activity within an area corresponding to a location of a camera unit is detected. In response to detection of the event, the camera unit is controlled to capture one or more images of the area corresponding to the location of the camera unit. The one or more images captured by the camera unit are analyzed to determine whether the one or more images include image data that is indicative of relevant physical activity within the area corresponding to the location of the camera unit. The one or more images are handled based on the determination of whether the one or more images include image data that is indicative of relevant physical activity within the area corresponding to the location of the camera unit.
