Video Doorbell Passcode Verification for Temporary Home Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for granting access to premises lack efficient methods for verifying who accessed the home, when access occurred, and why, leading to potential security system false alarms and compromised security when homeowners are away.
Innovation Solution
A system utilizing optically capturable QR codes and audible passcodes for multi-factor authentication, where a QR code is sent to a visitor's mobile device and an audible passcode is provided via a voice call, allowing verification through a video doorbell device for secure temporary access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical home key or PIN is shared with visitors, then access to the home is granted, but the ability to verify who accessed the home, when, and why is lost
Solution Approach 1:
The patent replaces physical mechanical access methods (keys, PINs) with an electronic system that uses video doorbell cameras, QR codes, and audio capture to verify access. The system captures visual and auditory data to identify visitors and verify their authorization, thereby maintaining ease of access while recovering the ability to verify access details.
Solution Approach 2:
The patent introduces an intermediary system (video doorbell device with QR code and audio verification) between the visitor and the door lock. This intermediary captures and transmits verification data to the control device, which then authenticates the visitor before granting access, thus enabling both easy access and comprehensive verification.
2Ease of operation
If the security system is disarmed to allow visitor access, then the visitor can enter without triggering alarms, but the home is left unprotected for the entire day
Solution Approach 1:
The patent performs preliminary verification of the visitor's identity and authorization before the door lock is unlocked. The video doorbell captures visual and auditory data, the control device verifies the visitor against authorized lists, and only after successful verification does the system disarm the security system and unlock the door. This ensures the home remains protected until a verified visitor actually needs access.
Solution Approach 2:
The patent makes the security system state dynamic rather than static. The system transitions between armed and disarmed states based on real-time verification events. When a verified visitor approaches, the system dynamically disarms to allow access, then automatically re-arms after the visitor enters, ensuring continuous protection while enabling temporary access when needed.
3Reliability
If the security system remains armed during grocery delivery, then the home stays protected, but false alarms are triggered when delivery personnel attempt entry
Solution Approach 1:
The patent performs preliminary verification of the visitor's identity and authorized access status before the door lock is unlocked. The video doorbell captures visual and auditory data, the control device verifies the visitor against authorized lists, and only after successful verification does the system disarm the security system and unlock the door. This ensures the home remains protected until a verified visitor actually needs access.
Solution Approach 2:
The patent introduces an intermediary verification system (video doorbell with QR code and audio verification) between the delivery person and the door lock. This intermediary captures and transmits verification data to the control device, which then authenticates the delivery person before granting access, thereby preventing false alarms while maintaining security.
4Reliability
If multi-factor authentication is implemented with QR codes and audible passcodes, then access verification is enhanced, but the device complexity increases
Solution Approach 1:
The patent makes the video doorbell device multi-functional by having it serve as both a security monitoring device and an authentication device. The same device that monitors the premises also captures QR codes and audible passcodes for verification, eliminating the need for separate authentication hardware and reducing overall system complexity while enhancing verification reliability.
Solution Approach 2:
The patent merges the authentication functions (QR code scanning, audible passcode verification) into the existing video doorbell system and control device. By combining these functions into devices that are already present in the security system, the patent avoids adding separate complex authentication hardware, thus enhancing verification while minimizing the increase in device complexity.

AI summary
According to some embodiments, a system is provided. The system includes at least one computing device in communication with a premises monitoring system, where the premises monitoring system is configured to monitor a premises. At least one computing device is configured to receive an image of an optically capturable passcode, the image being captured by the premises monitoring system, receive recorded audio of a person speaking an audible passcode captured by the premises monitoring system, authenticate the person based on the optically capturable passcode and the audible passcode, determine that the person is permitted access to the premises according to an access control policy, and, in response to authenticating the person and determining that the person is permitted access to the premises, cause a lock securing an access point of the premises to unlock.
