Ambarella H2-A1-RH 1GHz Video SoC With 4KP90 Video Encoding For Dashcam

Shenzhen Mingjiada Electronics Co., Ltd., a globally renowned distributor of electronic components, leverages its formidable supply chain integration capabilities to now offer Ambarella's H2-A1-RH 1GHz video system-on-chip. This flagship chip, supporting 4K P90 ultra-high-definition encoding, is setting a new performance benchmark for next-generation premium dashcams and in-vehicle visual systems.

Core technological breakthroughs of the H2-A1-RH:

The core value of Ambarella's H2-A1-RH chip lies in elevating dashcam video quality to unprecedented levels. Conventional 4K dashcams typically only support 30 frames per second recording, which can result in blurring during high-speed driving or when capturing rapidly moving objects.

The H2-A1-RH's greatest innovation lies in its support for 90 frames per second recording at 4K resolution. This high frame rate is crucial for capturing details during high-speed travel, significantly reducing motion blur in fast-moving objects and ensuring critical information like licence plate numbers and pedestrian details remains clearly discernible.

This chip employs advanced image processing and compression algorithms to deliver high-quality video output at low bitrates, effectively managing storage space while maintaining image integrity.

Core Advantages of H2-A1-RH:

Ultimate Imaging Performance: The H2-A1-RH chip supports ultra-high frame rate video encoding at 90 frames per second (P90) in 4K resolution (3840×2160). Compared to mainstream 4K30 solutions, it captures three times more visual information per second. This not only renders daytime driving footage with exceptional detail but also ensures smooth, clear, and blur-free video during high-speed manoeuvres or low-light night-time conditions. This significantly enhances the success rate of number plate recognition and accident detail reconstruction.

Powerful Processing Core: The chip integrates a high-performance ARM processor operating at up to 1GHz. This not only delivers ample computational power for real-time encoding and compression of ultra-high-definition video but also reserves capacity for advanced driver-assistance systems (ADAS) functions such as forward collision warning and lane departure warning. This evolution transforms dashcams from mere “recording devices” into proactive “preventative tools”.

Superior Image Processing Technology: The chip integrates Ambarella's advanced Image Signal Processor (ISP) and supports true HDR/WDR (Wide Dynamic Range) technology. It effectively handles complex lighting scenarios with extreme brightness contrasts, such as tunnel entrances/exits and oncoming headlights at night. It automatically balances details in both bright and dark areas, preventing overexposure or underexposure, ensuring every frame is usable and reliable.

Technical parameter analysis of the H2-A1-RH:

The technical specifications of Ambarella's H2-A1-RH chip are meticulously tailored for dashcam applications. Its core technical highlight is the capability to record at 90 frames per second in 4K resolution (typically 3840×2160 pixels).

Compared to conventional 30fps 4K recording, the 90fps frame rate reduces the time interval between frames by two-thirds, significantly minimising motion blur. This makes it particularly suitable for capturing vehicles travelling at high speeds and rapidly moving objects.

The chip's integrated image signal processor (ISP) optimises sensor-captured imagery through technologies such as automatic white balance, noise suppression, and dynamic range enhancement, thereby elevating video quality.

The H2-A1-RH chip's low-power design merits attention, proving crucial for dashcams requiring prolonged operation. This design effectively minimises heat generation and enhances device stability.

Application Prospects for H2-A1-RH:

Dashcams equipped with Ambarella's H2-A1-RH chip transcend basic recording functionality to become the ‘visual perception hub’ of intelligent vehicles.

Professional-grade recording: Meets the stringent demands of ride-hailing services, transport fleets, and insurance sectors for maximum clarity and evidence reliability. 4K P90 footage serves as authoritative evidence for accident liability determination, effectively mitigating staged collision risks.

Advanced Driver Assistance Systems (ADAS): Robust computational power enables real-time local execution of multiple computer vision algorithms, delivering safety features such as lead vehicle departure alerts and lane-keeping assistance to enhance proactive driving safety.

Immersive Driving Experience: Ultra-high-definition video enables generation of driving trajectory video logs (Vlogs) to capture scenic journeys. Integrated with GPS modules, it synchronises video with geographical location data, enriching connected vehicle application scenarios.

Extended In-Vehicle Monitoring Systems: The chip's high performance equally suits premium in-vehicle surround-view systems and Driver Monitoring Systems (DMS), delivering reliable visual data processing capabilities for intelligent cockpits and autonomous driving perception layers.
