Frame Grabber CN312S


AVerMedia AVerGrabber CN312S, the 2K SDI Dual-Channel M.2 Video Capture Card, is equipped by two SDI channels with the embedded audio. With its SDI video source input, it is able to support an astounding uncompressed real-time video capture resolution of up to 2K (2048 x 1080).

At the frame rate of 60 fps, CN312S can improve the quality of a wide range of media recorded for businesses, universities, broadcasting, and manufacturing facilities, which can eventually provide a more lifelike and smooth video playback experience.

Wide Temperature and Conformal Coating Design

AVerMedia delivers this advanced solution, which is capable of withstanding the extreme temperature environment without compromising the video functionality. CN312MW (Wide Temperature Version) can offer the stable operation in the temperature range from -20°C to 70°C (-4°F to 158°F). Furthermore, CN312MC (Wide Temperature with Conformal Coating Version) thermally robust product is specifically designed to provide great reliability for the rugged and industrial applications to against moisture, dust, or chemicals.

M.2 Compact Form Factor with High 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 2280, CN312SW is the ideal solution for the education sector and industrial PCs, it features PCIe Gen2x4 interface with a theoretical bandwidth of 8 Gb/s.

Hardware Video Processing

CN312S has built-in AVerMedia Video Engine technology which implements most useful video enhancing features to significantly reduce the efforts of CPU and the software development.  In other words, this can help our clients to achieve the better cost saving of the hardware platform and the development resource.
