Wireless Video Doorbell with Proximity Detection and Remote Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for receiving visitors at homes or offices lack effective means for interactive messaging, security, and access control, particularly when the resident is absent, and often fail to distinguish between welcome and unwelcome visitors until the door is opened, posing security risks.
Innovation Solution
An audio-video communication system comprising a wireless exterior module with a proximity sensor, video camera, microphone, speaker, transmitter, and receiver, controlled by a computerized controller with a software application for real-time communication and access management, including a remote peripheral device for viewing and interacting with visitors, and an electronically actuated lock for secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional door answering system is used, then the resident can receive visitors, but the resident cannot remotely interact with or monitor visitors, creating security risks and inconvenience
Solution Approach 1:
The patent introduces a video communication device as an intermediary between the visitor and the resident. This device enables remote interaction through video and audio transmission, allowing the resident to see and hear visitors without opening the door, thus improving ease of operation while maintaining security protection
Solution Approach 2:
The patent replaces the traditional mechanical door-opening mechanism with an electronic video communication system. Instead of physically opening the door to receive visitors, the resident uses a video device to interact remotely, substituting mechanical action with electronic communication to achieve both convenience and security
2Ease of operation
If the resident opens the door to receive visitors, then interaction is possible, but security risks increase due to inability to identify visitors beforehand
Solution Approach 1:
The patent enables preliminary identification of visitors through video transmission before the door is opened. The resident can view the visitor's appearance, demeanor, and purpose in advance via the video device, allowing preliminary assessment of security risks before physical contact occurs
Solution Approach 2:
The patent implements a feedback loop where the resident can observe the visitor through video, assess security risks, and make informed decisions about whether to open the door. The system provides real-time visual and auditory feedback, enabling the resident to evaluate visitor legitimacy and respond appropriately
3Adaptability or versatility
If no message system is provided, then the system is simple, but the resident cannot leave interactive messages when absent, causing inconvenience
Solution Approach 1:
The patent integrates multiple functions into a single video communication device, including video transmission, audio communication, and messaging capabilities. This multi-functional approach allows the resident to send messages, receive calls, and interact with visitors through one device, improving adaptability while limiting the increase in overall system complexity

AI summary
An audio-video communication system comprises a wireless exterior module located proximate an entrance, a computerized controller running a software application, and a remote peripheral device. The wireless exterior module includes a proximity sensor for detecting a person at the entrance, a video camera for recording an image of the person at the entrance, a microphone for recording the person at the entrance, a speaker for playing audio to the person at the entrance, a transmitter for communicating sounds and images of the person at the entrance, and a receiver for receiving communications at the wireless exterior module. The computerized controller is disposed in wireless electronic communication with the wireless exterior module via the transmitter and the receiver of the wireless exterior module. The remote peripheral device is configured to electronically communicate with the computerized controller for viewing an image from the video camera communicated from the wireless exterior module.
