The AVerMedia AVerGrabber CN312M dual-channel M.2 video capture card features one HDMI channel and one SDI channel with embedded audio. With its HDMI and SDI video source inputs, it supports an impressive uncompressed real-time video capture resolution of up to 2048 x 1080 60fps (SDI)/ 1920 x 1200 60fps (HDMI).
At a frame rate of 60 fps, the CN312M can improve the quality of a wide range of media recorded for businesses, universities, broadcasters, and manufacturing facilities, providing a more lifelike and smooth video playback experience.

Wide-Temperature and Conformal-Coating Design
AVerMedia provides this advanced solution, which can withstand extreme-temperature environments without compromising video functionality. The CN312MW (Wide Temperature Version) offers stable operation across a temperature range of -20°C to 70°C (-4°F to 158°F). Furthermore, the CN312MC (Wide Temperature with Conformal Coating Version) is a thermally robust product specifically designed to provide high reliability for rugged and industrial applications exposed to moisture, dust, or chemicals.

The Latest Compact M.2 Form Factor with High Resolution
The compact M.2 form factor has become increasingly popular. A PCI Express M.2 device is extremely compact and designed to fit seamlessly into small-footprint embedded systems for industrial applications. Compliant with the widely adopted M.2 2280 standard, the CN312M is an ideal solution for the education sector and industrial PCs, featuring a PCIe Gen2x4 interface with a theoretical bandwidth of 16 Gb/s.
Hardware Video Processing
The CN312M features built-in AVerMedia Video Engine technology, which implements useful video-enhancement features to significantly reduce CPU workload and software-development effort. In other words, this can help our customers reduce the cost of the hardware platform and development resources.

Versatile AVerMedia SDK
Industrial customers can develop vertical applications flexibly and efficiently using AVerMedia’s exclusively designed SDK, with features such as device control, media capture, A/V processing, and more.
