Surveillance Camera Event-Driven Activation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surveillance systems lack efficient methods to dynamically adjust camera settings based on monitored events and patterns, leading to suboptimal resource utilization and increased power consumption.
Innovation Solution
A surveillance system comprising a server and network cameras that communicate to detect events, recognize patterns, and adjust camera settings such as capturing mode, orientation, zoom, resolution, and transmission rates based on determined events, allowing for optimized operation and reduced power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera operates continuously to monitor events, then monitoring reliability is improved, but power consumption increases
Solution Approach 1:
The camera alternates between active monitoring periods and sleep periods, using periodic wake-up intervals to check for events rather than continuous operation. This reduces power consumption while maintaining monitoring reliability through scheduled checks and event-triggered activations.
Solution Approach 2:
The camera uses onboard motion detection and event detection capabilities to autonomously determine when activation is necessary, eliminating the need for continuous server communication and enabling self-managed power-saving operations.
2Measurement precision
If the camera captures high-resolution images continuously, then measurement precision is improved, but energy consumption increases
Solution Approach 1:
The camera uses low-resolution preview images for routine monitoring and only activates high-resolution capture when events are detected. This partial use of full capabilities reduces energy consumption while maintaining measurement precision when actually needed.
Solution Approach 2:
The camera dynamically changes image resolution parameters based on operational conditions, using lower resolution during normal operation and switching to high resolution only when events require detailed documentation.
3Measurement precision
If the camera remains active to detect events, then detection precision is improved, but power consumption increases
Solution Approach 1:
The camera performs preliminary low-power motion detection using onboard sensors before activating full imaging capabilities. This preliminary action detects potential events without requiring the camera to remain fully active, reducing power consumption while maintaining detection precision.
Solution Approach 2:
The camera uses motion detection algorithms and onboard sensors as intermediaries between passive sleep mode and active high-power imaging mode, enabling event detection without continuous full operation.

AI summary
A surveillance system including a surveillance server and at least one network camera is provided. The surveillance server includes: a communication interface configured to communicate with a network camera; and a processor configured to determine an event based on at least one image received from the network camera during a first period, determine an activation time of the network camera based on the event, and transmit an event reaction request including information about the activation time to the network camera during a second period after the first period.
