Automated Camera Privacy Shutter Control by Display Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network-connected video cameras pose privacy and security concerns as they may capture and transmit video unbeknownst to the end user, deterring potential users from installation.
Innovation Solution
An automated shutter control system for video cameras that blocks or unblocks the lens based on the power consumption state of an attached electronic display, using power sensing circuitry to determine if the display is in standby or active mode, with customizable thresholds for different makes and models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a network-connected video camera is installed to enable remote face-to-face communications, then communication capability is improved, but privacy and security concerns arise due to unauthorized video capture
Solution Approach 1:
A shutter mechanism is introduced as an intermediary component between the camera lens and the environment. This shutter acts as a mediator that can physically block or unblock the lens based on power consumption detection, preventing unauthorized video capture while allowing legitimate communication when needed
Solution Approach 2:
The system implements feedback by continuously monitoring power consumption of the electronic display and using this information to control the shutter position. When power consumption indicates the display is off, the shutter blocks the lens; when power consumption indicates the display is on, the shutter unblocks the lens, creating a closed-loop security system
2Object-affected harmful factors
If a shutter mechanism is added to block the camera lens, then privacy and security are improved, but device complexity increases
Solution Approach 1:
The shutter control system merges multiple functions into a single integrated mechanism: power consumption detection, control logic, and mechanical shutter actuation are combined into one unit that automatically responds to power state changes without requiring separate complex control systems
Solution Approach 2:
The system performs self-service by automatically detecting power consumption levels and controlling the shutter position without requiring manual user intervention. The mechanism self-regulates based on the power state of the electronic display, eliminating the need for complex user interfaces or manual control systems
3Extent of automation
If power sensing circuitry is used to detect display mode, then automation is improved, but manufacturing cost increases
Solution Approach 1:
The power sensing circuitry is designed to serve multiple functions: it detects power consumption levels, determines display mode (on/off), and triggers appropriate shutter responses. This multi-functional approach eliminates the need for separate complex detection and control systems, reducing overall manufacturing cost while maintaining automation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances security and privacy by automatically controlling the camera's field of view based on the display's mode, ensuring the camera is obscured when not in use and unobstructed when active, addressing the concerns of unauthorized video capture.
Implementation Method 1
power sensing circuitry comprising a circuitry that may measure an amount of power being supplied to the electronic display

AI summary
Various arrangements are presented that involve an automated shutter control system being used with a separate and distinct video camera. The automated shutter control system can include a shutter, a shutter motor, power sensing circuitry that measures an amount of power being supplied to the electronic display, and a processing system. The processing system controls the shutter motor that causes the shutter to be actuated to an open position or a closed position based on the amount of power being supplied to the electronic display as measured by the circuitry of the power sensing circuitry.
