Introduction

The vehicle video requires high endurance and consistent writing speed of files recording. One famous electronics manufacturer In Japan that is specializing in driving recording cooperated with UDINFO for high-performance and heavy writing memory that fulfill In-Car Video recording requirements. The applications would require high reliability and durability. Since the camera is to support fleet management and law enforcement agency such as government and police department, the storage needs to pass certification and evaluated in extreme environments.

The authorities have In-Car Video recording systems to monitor transportation and activity. These cameras require storage to record video streams with consistent stability.

The devices require storage to capture video streams without encumbrance to speed and data capture. Due to storage NAND characteristics, most solutions might have recording speed drop issue due to garbage collection. UDinfo solution with optimized firmware met the requirement in delivering reliability, speed consistency integration, and data management.

Challenges

•Fulfill consistent writing speed requirements for vehicle cameras • •Resolve stable resolution camera file sizes to deliver high & stable write speeds avoiding data loss


 Solutions

. High performance 3D NAND

. Firmware optimization for video surveillance vide application.


Results

The Japanese partner provided an In-Car Video system with UDinfo’s micro-SD solution that can provides consistent writing and stable performance for vehicle connected cameras. The single-lens driving video would require one video file at a time, and UDinfo customized micro-SD can meet the specific requirements. 

For the dual-lens DVR, it would record up to 4 video files every time while the vehicles are in accident or in unexpected crash. The reliability and consistency are very important while recording these videos in the challenging circumstances. UDinfo recommended using higher capacity 3D TLC and pSLC solution to improve consistency and meet the system requirements. 

Not only did this fulfill the recording applications in those accident circumstances, but it also solved the inconsistency issue for In-Car Video platform.
