Monitoring Camera Prioritized Startup Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high power demand during startup of multiple monitoring cameras after a power outage can lead to a sudden load on the power grid, potentially causing an overload and unstable power supply, as all devices require power simultaneously, which can result in another power outage.
Innovation Solution
Implementing a method where monitoring cameras prioritize their startup based on assigned priorities, allowing only the first part of each camera to start up initially, and then the second part to start up in a prioritized order, thereby reducing the simultaneous power load on the grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If all monitoring cameras are restarted simultaneously after power restoration, then all cameras become operational quickly, but the power grid experiences high load and potential overload
Solution Approach 1:
The patent segments the camera network into priority groups (high priority and low priority cameras) and further divides startup into two phases: first part startup (processing unit, memory unit, network connection unit) for all cameras, and second part startup (picture sensor, lens controller, video streaming unit) for selected cameras. This segmentation allows the system to maintain productivity while reducing peak power load by controlling which cameras complete their startup sequence.
Solution Approach 2:
The patent implements periodic action by introducing time delays between the startup of different camera groups. High priority cameras are allowed to complete their second part startup before low priority cameras begin, creating a staged, periodic startup pattern rather than simultaneous activation. This temporal distribution reduces the instantaneous power load on the grid.
2Reliability
If all monitoring cameras start up their complete functions simultaneously, then full surveillance coverage is achieved immediately, but power consumption spikes causing unstable power supply
Solution Approach 1:
The camera functionality is segmented into two distinct parts: the first part (processing unit, memory unit, network connection unit) that provides basic operational capability, and the second part (picture sensor, lens controller, video streaming unit) that provides full surveillance function. By segmenting startup into these two phases, the system achieves a balance between reliability and power consumption.
Solution Approach 2:
The patent applies partial action by allowing only high priority cameras to complete their full startup sequence during the initial phase after power restoration. Low priority cameras remain in a partial startup state (first part only) until higher priority cameras have stabilized power consumption. This ensures critical surveillance coverage while avoiding excessive power spikes.
3Reliability
If high priority cameras are given priority startup, then critical surveillance is ensured, but low priority cameras experience delayed startup
Solution Approach 1:
The patent applies local quality by assigning different startup characteristics to different cameras based on their priority classification. High priority cameras receive immediate attention and are allowed to complete full startup, while low priority cameras experience delayed second part startup. This differentiated approach ensures critical surveillance needs are met without completely preventing low priority camera operation.
Solution Approach 2:
The patent implements preliminary action by having all cameras complete their first part startup (processing unit, memory unit, network connection unit) simultaneously before any camera begins its second part startup. This preliminary phase ensures all cameras are partially operational and ready to transition to full functionality in a controlled sequence, minimizing overall startup time while maintaining priority-based ordering.

AI summary
The present disclosure relates to a method performed by a first monitoring camera (101) for handling startup. The first monitoring camera (101) detects that a power supply state of has changed from off to on. The first monitoring camera (101) initiates startup of a first part (103a) when the power supply state is on. When the startup is complete, the first monitoring camera (101) determines if its first startup priority is higher than, lower than or the same as a second startup priority of a second monitoring camera (110). The first monitoring camera (101) initiates startup of its second part (105a) if the first startup priority is higher or the same as the second startup priority. If the first startup priority is lower than the second startup priority, the first monitoring camera (101) delays startup of its second part (105a) until startup instructions have been received.
