Body-Mounted Camera Delivery Security via Video-Triggered Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As online purchases increase, there is a growing need for secure home delivery systems that protect packages from theft and burglary, as existing methods lack robust security protocols for unattended deliveries.
Innovation Solution
A body-mounted camera system that streams video and stores footage locally, allowing remote monitoring and unlocking of entry points only when video recording is initiated, ensuring secure delivery operations without requiring a home occupant's presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a body-mounted camera system is implemented to provide real-time video monitoring and local storage, then delivery security and evidence preservation are improved, but device complexity and cost increase
Solution Approach 1:
The system divides security monitoring into multiple functional segments: real-time video streaming for immediate security monitoring, local storage for evidence preservation, and selective unlocking based on video verification. Each segment operates independently but integrates seamlessly, improving reliability without requiring a monolithic complex system.
Solution Approach 2:
The body-mounted camera serves multiple functions simultaneously: it acts as a security monitoring device, an evidence recording device, and a verification trigger for door unlocking. This multi-functionality reduces the need for separate dedicated devices, thereby limiting the increase in overall system complexity while enhancing delivery security.
2Reliability
If real-time video streaming and local storage are implemented, then security monitoring capability is improved, but energy consumption increases
Solution Approach 1:
The camera system operates in periodic cycles rather than continuously: it activates video recording and streaming only when delivery events occur or when verification is needed, then enters low-power modes between events. This periodic operation maintains security monitoring capability while significantly reducing average energy consumption.
Solution Approach 2:
The system automatically manages its own power consumption by using motion sensors and event triggers to activate recording functions only when necessary, without requiring continuous manual intervention. The local storage capability allows the camera to self-preserve evidence even during temporary power interruptions or network outages.
3Reliability
If door unlocking is restricted to when video recording is detected, then security against unauthorized entry is improved, but delivery operation speed decreases
Solution Approach 1:
The system performs preliminary verification by detecting and validating video recording status before authorizing door unlocking. This preliminary action ensures security by confirming that video monitoring is actively recording the delivery event, while the automated nature of the verification process prevents significant delays in the overall delivery operation.

AI summary
A delivery monitoring system comprises a portable camera positioned on a delivery person; a camera activation application executed by a mobile electronic device to control a video-generating operation of the portable camera; and a special-purpose processor that outputs a data instruction to an electronic locking device to unlock an entrance to a location for delivering an item by the delivery person only when the portable camera is recording video.
