Dual-Camera A/V Device Parcel Theft Deterrence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Parcel theft is a persistent problem due to parcels being left unattended at home entrances during deliveries, especially with the rise of online commerce, making them vulnerable to theft and difficult to deter or identify.
Innovation Solution
A dual-camera audio/video recording and communication device that monitors a drop-off zone, determines when a parcel is placed or removed, and transmits notifications to the user, with features to assess authorization and generate alerts for unauthorized removal, using image data, RFID, and AIDC technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If parcels are left unattended at home entrances for delivery, then delivery convenience is improved, but vulnerability to theft increases
Solution Approach 1:
The system performs preliminary actions by monitoring the drop-off zone before theft occurs. The camera continuously captures images and the processor analyzes them to detect parcel placement, preparing the system to respond immediately when unauthorized removal happens, thus preventing the harmful effect before it completes.
Solution Approach 2:
The system establishes feedback loops where the camera monitors the parcel, the processor analyzes image data to detect removal events, and the notification system provides real-time alerts to users. This continuous feedback mechanism allows the system to respond dynamically to parcel status changes, deterring theft through immediate user awareness.
2Reliability
If A/V recording devices are installed at home entrances, then crime detection capability is improved, but device complexity increases
Solution Approach 1:
The A/V recording device is designed to perform multiple functions: it monitors for parcel delivery, detects unauthorized removal, captures evidence through imaging, and sends notifications. This multi-functionality consolidates what could be multiple separate systems into one device, improving crime detection capability while managing complexity through integration rather than proliferation of components.
Solution Approach 2:
The device performs self-service through automated image analysis. The processor automatically analyzes captured images to detect parcel placement and removal events without requiring manual review, and automatically sends notifications when theft is detected. This automation reduces the need for additional monitoring equipment or manual intervention systems.
3Measurement precision
If dual-camera systems are used to monitor drop-off zones, then parcel theft detection accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The monitoring system is segmented into two specialized camera functions: one camera optimized for capturing wide-area drop-off zone surveillance and another for detailed parcel identification. This segmentation allows each camera to be optimized for its specific role, improving overall detection accuracy while using standard off-the-shelf components rather than requiring a single expensive high-performance camera system.
Solution Approach 2:
The system uses image copying and analysis techniques where the processor captures multiple images from both cameras and creates composite views or compares images to detect parcel removal. This digital copying and analysis approach improves detection accuracy by providing multiple perspectives and verification opportunities without requiring additional physical sensors or expensive specialized detection equipment.
