Product Overview
The ALI121-Y is a 1MP industrial GMSL camera module built on an automotive-grade CMOS image sensor and engineered for demanding low-speed unmanned vehicle applications. The module combines outstanding imaging performance, high-speed reliable transmission, and rugged environmental resilience to deliver a dependable, efficient vision solution for advanced machine vision systems.
For imaging performance, the module’s built-in high-performance ISP handles auto exposure, color correction, and noise reduction at the sensor side, outputting an excellent-quality YUV422 video stream directly. Its 120 dB high dynamic range preserves detail in both bright and dark regions of high-contrast scenes — preventing local overexposure or underexposure where strong light and shadow coexist.
For system integration, the module uses a GMSL high-speed serial interface for long-distance, high-bandwidth, interference-resistant transmission, and supports Power over Coax (PoC). A single cable carries both power and video, dramatically simplifying system wiring and reducing deployment complexity and overall cost.
For reliability and environmental resilience, the module is rated IP67 — fully dust-tight and able to withstand brief immersion — handling dusty, humid, and other harsh conditions with ease. Its wide operating temperature range ensures stable operation in extreme heat and cold, meeting the requirements for long-term outdoor and industrial deployment.
In summary, the ALI121-Y suits low-speed unmanned vehicles, industrial inspection, intelligent transportation, and many other domains, providing a solid perception foundation for intelligent vision systems with high integration, high image quality, and high environmental tolerance.
