AVNT Parking Video Access Using Public CCTV Feeds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Parking video recording devices, or black boxes, face issues of increased battery power consumption and insufficient storage capacity, particularly affecting drivers with less frequent vehicle usage.
Innovation Solution
A system utilizing an audio video navigation telematics (AVNT) to access public CCTV videos via an external server, allowing users to select and store or transmit parking videos, thereby reducing power usage and increasing storage capacity by leveraging external video sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the parking video recording device uses the vehicle's battery power for continuous recording, then the video recording function is maintained, but the battery power consumption increases
Solution Approach 1:
The patent introduces public CCTV cameras as an intermediary resource to provide parking surveillance footage. Instead of relying solely on the vehicle's black box camera, the system accesses external CCTV feeds from surrounding areas, thereby reducing the need for continuous local recording and lowering battery consumption while maintaining surveillance availability.
Solution Approach 2:
The system integrates multiple video sources (vehicle's own camera and public CCTV cameras) into a unified parking surveillance solution. This multi-functional approach allows the system to switch between different recording sources depending on availability and power conditions, optimizing both energy usage and recording reliability.
2Quantity of substance
If the parking video recording device stores all parking videos locally, then the video storage capacity is sufficient, but the device complexity increases
Solution Approach 1:
The patent extracts the video storage function from the vehicle's black box device and relocates it to external servers. The black box only needs to manage minimal local storage for recent clips, while historical parking videos are stored remotely on server infrastructure, significantly reducing the storage burden and complexity of the in-vehicle device.
Solution Approach 2:
The system transitions from a single-dimension local storage architecture to a multi-dimensional storage solution that combines minimal local storage with cloud-based remote storage. This dimensional expansion allows the system to maintain sufficient video storage capacity while keeping the vehicle device simple and lightweight.
3Duration of action of moving object
If the black box records videos in parking mode for extended periods, then the video storage capacity is充分利用, but the battery power consumption increases
Solution Approach 1:
Public CCTV cameras serve as intermediary recording sources that extend the effective recording duration without consuming the vehicle's battery power. The system can access these external feeds indefinitely, overcoming the limitation of local battery-powered recording duration.
Solution Approach 2:
The system implements periodic checking and switching between different video sources (local camera and public CCTV feeds). Instead of continuous local recording, it periodically accesses external feeds when available, reducing power consumption while maintaining extended recording capability.

AI summary
According to an embodiment, a parking video recording system comprises an AVNT installed in a vehicle and a video recording device, wherein the AVNT is configured to receive an intent to use public CCTV from a user, transmit a location of the vehicle to an external server, and receive at least one public CCTV video within a predetermined distance from the location of the vehicle from the external server.
