Dual-Camera Vehicle Security Mount for Low-Power Threat Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle dashcams do not effectively monitor and record when the vehicle is stationary due to concerns about power consumption and the need for professional installation, leaving vehicles vulnerable to damage and theft.
Innovation Solution
An in-vehicle security device with dual image capture devices and object detection modules that minimize power consumption by activating only when an object is detected, providing a field of view that extends beyond the rearview mirror into the cabin, and includes radar modules for 360-degree motion detection and ranging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dashcams continuously record video footage to provide security protection, then reliability of security monitoring is improved, but use of energy increases causing battery drain
Solution Approach 1:
The system implements periodic action by switching between sleep mode and active recording mode based on detected events. The camera remains in low-power sleep mode during normal operation and only activates recording when motion or impact sensors detect a security-relevant event, thus maintaining reliability while minimizing energy consumption.
Solution Approach 2:
The system employs self-service through automatic event detection and triggering mechanisms. Sensors automatically detect security events and trigger recording without user intervention, enabling the system to provide continuous security monitoring reliability while consuming minimal energy by only activating when needed.
2Device complexity
If professional installation of head units is required to ensure proper functionality, then device complexity is reduced, but ease of operation deteriorates due to installation barriers
Solution Approach 1:
The system is segmented into modular components including the camera unit, mounting bracket, and sensor elements that can be independently installed. This segmentation allows users to install each component separately without requiring professional calibration, reducing installation barriers while maintaining device functionality.
Solution Approach 2:
The system enables self-service installation through user-friendly mounting mechanisms and automatic configuration. The camera and sensors are designed to be easily mounted by consumers without professional assistance, and the system automatically configures itself upon installation, eliminating the need for technician calibration while maintaining proper functionality.

AI summary
An in-vehicle security device mountable to a surface to the rear of a rear-view mirror of a vehicle, comprising: a first image capture device configured to receive images in a first direction relative to the security device; a second image capture device facing a second direction, the second direction different from the first direction; and a first object detection module configured to detect the presence of an object exterior to a vehicle in which the security device may be mounted; wherein the first image capture device and second image capture device are arranged to begin capturing images and/or video responsive to the first object detection module detecting the presence of an object exterior to a vehicle in which the security device may be mounted.
