1080P 60 FPS HDMI video capture
The CM311-H is a Mini-PCIe HDMI frame grabber capable of capturing video up to 1080p@60. With integrated AVerMedia Video Engine technology, it can perform various video-processing tasks, such as frame-rate conversion, deinterlacing and scaling, without consuming the computing power of the target platform.
It provides all the functions required to capture Full HD video for industrial and commercial markets, including data recorders, medical imaging devices, machine vision systems and other industrial imaging applications. The CM311-H is designed to shorten development time and provide integrators with a complete, rugged solution for building their own applications.
Mini PCIe form factor and vibration resistance
The compact Mini PCIe card form factor is ideal for small-footprint embedded systems. It is also suitable for solutions requiring vibration resistance, while the mounting holes make it appropriate for in-vehicle, military and industrial applications.
Support for up to 4:4:4 10-bit RGB and YUV
The CM311-H supports up to 4:4:4 10 bit RGB and YUV, enabling it to capture colours across the full colour spectrum for richer, brighter image quality. The 10-bit colour-depth support is particularly useful in medical imaging applications, where the slightest colour variation in an image may indicate different conditions or stages of disease. This may help doctors diagnose patient conditions accurately.
