Frame Grabber CN311-H

M.2 Compact Form Factor with 4K 30fps Resolution

Nowadays, the M.2 compact form factor has become the hot trend. The dimension of a PCI Express M.2 is extremely compact and designed perfectly to fit into small-footprint embedded systems for industrial applications. Conforming to the most popular standard of M.2, CN311-H is the ideal solution for the education sector and industrial PCs, it features PCIe Gen2 x2 interface with a theoretical bandwidth of 8 Gb/s.

Compatible with HDMI 1.4a standards, CN311-H enables single channel 4096×2160 resolution at 30fps loss-less video data throughput, capable of either capturing or recording at 4096×2160 @ 30fps.

Hardware Video Processing Technology

AVerMedia hardware-based video engine technology implements practical video processing functions such as de-interlacing for a sharper image, color space conversion for more true-to-life video color and resolution scaling.

I/O Board Design with HDMI Micro Coaxial Cable

Unlike most of M.2 capture cards, AVerMedia makes a breakthrough in the I/O board design. Connected via an HDMI micro coaxial cable, CN311-H can convey 4K video data efficiently, steadily and also benefit the configuration of embedded systems.

4:4:4 10 bit RGB and YUV

Support up to 4:4:4 10-bit RGB and YUV

CN311-H can support up to 4:4:4 10 bit RGB and YUV, meaning it can capture colors across the full color spectrum for richer and brighter image quality. The 10-bit color depth support is especially useful in the medical imaging applications where images with the slightest color variation may indicate different conditions or stages of diseases. This in turn may assist doctors in accurately diagnosing patient conditions.


Versatile AVerMedia SDK
