The AVerMedia AVerGrabber CN312S, a 2K SDI Dual-Channel M.2 video capture card, features two SDI channels with embedded audio. Through its SDI video source input, it supports an impressive uncompressed real-time video capture resolution of up to 2K (2048 x 1080).
At a frame rate of 60 fps, the CN312S can improve the quality of a wide range of media recorded for businesses, universities, broadcasting and manufacturing facilities, providing a more lifelike and fluid 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 CN312SW (Wide Temperature Version) provides stable operation across a temperature range of -20°C to 70°C (-4°F to 158°F). Furthermore, the CN312SC (Wide Temperature with Conformal Coating Version) is a thermally robust product specifically designed to provide high reliability in rugged and industrial applications, protecting against moisture, dust or chemicals.

The Latest M.2 Compact Form Factor
The compact M.2 form factor has become increasingly popular. A PCI Express M.2 card is extremely compact and ideally suited to small-footprint embedded systems for industrial applications. Compliant with the widely used M.2 2280 standard, the CN312SW is an ideal solution for the education sector and industrial PCs, featuring a PCIe Gen2x4 interface with a theoretical bandwidth of 8 Gb/s.
Hardware Video Processing
The CN312S features built-in AVerMedia Video Engine technology, which provides useful video-enhancement functions that significantly reduce CPU workload and software-development effort. In other words, it can help our customers reduce the cost of the hardware platform and development resources.

Versatile AVerMedia SDK Support
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.
