Vehicle Security Camera Layout for 360-Degree Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles are vulnerable to damage and theft when unattended due to the limitations of existing dashcams, which consume excessive power when stationary and require professional installation, deterring users from installing aftermarket security systems.
Innovation Solution
A security system comprising two devices mounted in different locations within a vehicle, with object detection modules that share data to provide 360-degree motion detection, minimizing power consumption by activating image capture only when threats are detected, and allowing easy installation without professional technicians.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dashcams are used to provide vehicle security when stationary, then security coverage is improved, but power consumption increases and battery depletion occurs
Solution Approach 1:
The system uses motion detection modules that periodically scan for motion and only activate image capture modules when motion is detected, rather than continuously recording. This periodic activation significantly reduces power consumption while maintaining security coverage when the vehicle is stationary
Solution Approach 2:
The motion detection modules automatically detect potential threats and trigger the image capture modules without requiring continuous power to the cameras. The system serves itself by using low-power sensors to activate high-power recording components only when needed
2Adaptability or versatility
If automotive head unit systems with peripheral sensors are installed, then processing capability is improved, but installation complexity increases and professional technician requirement arises
Solution Approach 1:
The system combines the image capture modules, motion detection modules, and processing capabilities into integrated devices that can be directly mounted in the vehicle without requiring separate head units and peripheral sensors. This integration simplifies installation while maintaining processing capability
Solution Approach 2:
The devices are designed to perform multiple functions (image capture, motion detection, data processing, and communication) within single integrated units, eliminating the need for separate peripheral devices and reducing installation complexity
3Reliability
If multiple image capture modules are activated continuously for 360-degree coverage, then security detection capability is improved, but power consumption increases
Solution Approach 1:
Instead of continuously activating all image capture modules, the system uses motion detection modules to periodically monitor for threats and only activates specific image capture modules when motion is detected in their respective zones, reducing overall power consumption while maintaining 360-degree security coverage
Solution Approach 2:
The system extracts and separates the motion detection function from the image capture function, using low-power motion detection modules to filter and trigger only the necessary high-power image capture modules, thereby reducing unnecessary power consumption

AI summary
A security system for use in a vehicle includes a first device configured for mounting in a first location of a vehicle, and a second device configured for mounting in a second location of a vehicle different from the first location. The first device includes a first image capture sensor facing a first direction and a first object detection module operative to detect the presence of an object exterior to a vehicle in which the first device may be mounted. The second device includes a second image capture sensor facing a second direction and the second direction different from the first direction.
