Camera System Sleep Standby Mode Shift for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring camera systems consume excessive power, particularly when constantly operating, leading to increased battery replacement frequency and reduced usability, especially in battery-driven setups.
Innovation Solution
A monitoring camera system where cameras can shift between sleep and standby modes based on detection notifications, with a master device controlling operation modes to activate cameras only when necessary, reducing unnecessary power consumption by buffering and transmitting video data efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If monitoring cameras constantly operate to ensure continuous monitoring coverage, then monitoring reliability is improved, but power consumption increases
Solution Approach 1:
The camera system dynamically adjusts its operation state based on detection needs. When motion is detected, the camera transitions from sleep mode to active monitoring mode, ensuring reliable monitoring only when necessary while reducing power consumption during idle periods.
Solution Approach 2:
The system implements periodic detection cycles where cameras alternate between sleep mode and active monitoring mode. This periodic activation ensures that monitoring reliability is maintained through regular checks while significantly reducing overall power consumption compared to continuous operation.
2Area of stationary object
If multiple cameras operate simultaneously to provide comprehensive coverage, then monitoring coverage is improved, but power consumption increases
Solution Approach 1:
The monitoring area is segmented into multiple zones, each covered by a specific camera. When motion is detected in a particular zone, only the relevant camera activates while others remain in sleep mode. This segmentation allows comprehensive coverage to be maintained through coordinated activation of individual cameras rather than simultaneous operation of all cameras.
Solution Approach 2:
Instead of activating all cameras simultaneously for comprehensive coverage, the system activates only the minimum necessary number of cameras based on detection needs. This partial action approach maintains adequate monitoring coverage while significantly reducing power consumption compared to full system activation.
3Speed
If cameras activate quickly upon detection to ensure timely monitoring, then response speed is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary detection using low-power motion sensors before activating the full camera system. This preliminary action allows the camera to remain in sleep mode during idle periods and only activate when motion is detected, achieving timely response to events while minimizing overall power consumption.

AI summary
A first camera sends a first detection notification to a master device when detecting a person in a first imaging area, and starts transmission of a captured video of the first imaging area to the master device by shifting an operation mode from a sleep mode to a standby mode. The master device notifies a camera other than the first camera of a shift instruction to the standby mode in accordance with the first detection notification. The other camera shifts the operation mode from the sleep mode to the standby mode in accordance with the shift instruction to the standby mode, and starts buffering of a captured video of a second imaging area, and when detecting the person in the second imaging area in the standby mode, the other camera sends a second detection notification of the person to the master device, and starts transmission of the captured video of the second imaging area buffered before a first predetermined time period after a point of time at which the person is detected in the second imaging area, to the master device.
