Doorbell Camera Pre-Actuation Video Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing doorbell camera systems fail to provide timely and clear identification of visitors due to obstructed views and delayed video displays, leading to missed responses as homeowners cannot identify visitors promptly.
Innovation Solution
The system captures still images or video before the doorbell is actuated, using methods like motion detection, facial recognition, and light contrast analysis, and buffers video to ensure immediate delivery upon notification, allowing homeowners to respond promptly to visitor arrivals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the doorbell camera takes a picture when the doorbell is actuated, then the homeowner receives notification of the visitor, but the picture provides little useful information because the camera is obstructed by the visitor's hand
Solution Approach 1:
The system performs preliminary actions by continuously capturing video footage before the doorbell is actuated. When the doorbell is pressed, the system has already recorded the visitor's approach and initial position, providing useful identification information without obstruction. This preliminary recording allows the homeowner to see the visitor clearly before they reach the door and potentially block the camera view.
2Loss of information
If the doorbell camera begins to record video when the doorbell is actuated, then the homeowner receives video footage of the visitor, but the video is delayed in being displayed on the control panel due to buffering
Solution Approach 1:
The system continuously records video in advance of the doorbell actuation, so when the doorbell is pressed, the video is already captured and can be immediately transmitted to the control panel without buffering delays. The preliminary continuous recording ensures that the video feed is ready for immediate display, eliminating the delay that would occur if recording started only after the doorbell was actuated.
3Productivity
If the camera captures images only when the doorbell is actuated, then the system uses less storage and processing resources, but the homeowner's inability to identify the visitor in a timely manner may result in the visitor departing before the homeowner can respond
Solution Approach 1:
The system uses periodic action by continuously capturing video at regular intervals rather than only when the doorbell is actuated. This continuous periodic recording ensures that the visitor is captured during their approach, providing timely identification information. The periodic capture is optimized to balance resource consumption with the need for timely visitor identification, recording at a rate sufficient to capture the visitor but not excessively high to waste resources.

AI summary
Techniques are described for enhanced interactions for a security automation system using a doorbell camera. One method includes detecting, by the doorbell camera, an object located within a pre-determined distance from the doorbell camera; identifying, by the doorbell camera, a suggested security action for the security and automation system to perform based at least in part on the detecting; transmitting the suggested action to the security and automation system based at least in part on the identifying; and transmitting, in response to identifying the suggested security action, a message to a user associated with the security automation system regarding the suggested security action.
