Rear View Camera Wireless Video Streaming to Mobile Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles often lack timely rearview visibility when reversing, especially without factory-installed cameras, leading to potential hazards in various weather conditions.
Innovation Solution
A retrofitted rearview camera system that wirelessly streams live video to a mobile device, allowing the driver to display the rearview image before reversing, eliminating lag and providing real-time visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a factory-installed rear view camera system is used, then real-time rearview visibility is achieved, but device complexity and cost increase
Solution Approach 1:
The system divides the rearview camera functionality into independent modular components: a standalone camera unit with wireless transmission capability, a mobile device for receiving and displaying video feed, and optional integration interfaces for vehicle systems. This segmentation allows the camera to operate independently without requiring complex factory-installed integrated systems, reducing overall system complexity while maintaining reliable real-time rearview visibility.
2Device complexity
If a retrofitted rear view camera is used, then device complexity is reduced, but video transmission lag increases
Solution Approach 1:
The camera is configured to activate and begin wireless video streaming immediately when the vehicle enters reverse gear, before the driver needs to view the feed. The system pre-establishes the video transmission channel and ensures the mobile device is ready to receive the feed, eliminating activation delays. This preliminary action ensures real-time visibility without the lag associated with traditional retrofitted systems that require manual activation or processing delays.
3Ease of operation
If wireless streaming is used, then ease of operation is improved, but energy consumption increases
Solution Approach 1:
The wireless video streaming operates in periodic intervals rather than continuously - the camera activates only when the vehicle enters reverse gear and transmits video feed during reverse operations. When the vehicle is in forward gear or parked, the camera remains inactive or in a low-power state. This periodic operation maintains ease of use with automatic activation while significantly reducing overall energy consumption compared to continuous streaming.

AI summary
A method may include detecting, by a mobile device, a first signal transmitted from a mobile device mount located in a vehicle and transmitting, by the mobile device and in response to detecting the first signal, a second signal to a vehicle system interface device. The method may also include sending, by the vehicle system interface device and in response to receiving the second signal, a third signal to a camera configured to capture video data associated with objects located at least one of behind or to the side of the vehicle and transmitting video data by the camera, in response to receiving the third signal. The method further includes receiving, by the mobile device, the video data transmitted by the camera and automatically displaying, by the mobile device, the received video data.
