Ensuring Heavy Writing and Endurance on Vehicle Transportation Recording
-High-performance Storage for In-Car Video
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. These applications require high reliability and durability. Since the camera is to support fleet management and law enforcement agencies such as government and police departments, 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 solutions with optimized firmware meet 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 provide 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 accidents or in unexpected crashes. This reliability and consistency are especially important when recording videos in challenging circumstances. UDinfo recommended using higher capacity 3D TLC and pSLC solutions 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 many other In-Car Video platforms.
