Doorbell Camera Server for Secure Remote Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door lock control systems face challenges in providing both security and user convenience, especially when controlling door locks remotely, as they often lack robust security measures to prevent accidental or unintentional unlocking.
Innovation Solution
A network server and operating method that integrates a doorbell camera, allowing real-time video monitoring and selective unlocking through a user terminal, with features like instant key values and password verification, and mode control signals for secure and convenient door lock management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If door lock control is enabled through wireless signal from remote terminal, then user convenience is improved, but security risk increases due to potential accidental or unauthorized unlocking
Solution Approach 1:
The system captures real-time video of the visitor through the doorbell camera and transmits it to the user terminal. The user can visually confirm the visitor's identity and presence before authorizing door lock unlocking, providing visual feedback that prevents accidental or unauthorized unlocking while maintaining remote control convenience
Solution Approach 2:
The doorbell camera system acts as an intermediary between the user and the door lock control function. Instead of directly controlling the door lock from the terminal, the system requires video verification through the camera first, which then enables the unlocking function. This intermediary step enhances security while preserving remote operation capability
2Ease of operation
If graphic interface includes door unlock button for remote control, then user convenience is improved, but security vulnerability increases due to accidental selection
Solution Approach 1:
The system displays the visitor's video image on the graphic interface before showing or enabling the door unlock button. This preliminary action of visual verification ensures that the user consciously recognizes who is at the door before authorizing unlocking, preventing accidental selections while maintaining ease of operation
Solution Approach 2:
The system prevents the door unlock function from being activated until video verification is completed. By requiring the video confirmation step first, the system counteracts the potential harmful effect of accidental unlocking before it can occur, while still providing a convenient one-touch unlock interface
