Frame Grabber CM313B


The CM313BW is a Mini PCIe HW encode video capture card which supports a single 3G-SDI input providing a nominal 2.970 Gbit/s interface for applications requiring HD 1080p video resolution. The CM313BW enables professionals to capture SD, HD, or 3G-SDI video footage in real-time 3G-SDI Video Input. The CM313BW offers stable operation in extreme environments under temperatures ranging from -40°C to 85°C (-40°F to 185°F).

Designed with 3G-SDI standards (SMPTE 424M), the CM313B offers uncompressed, H.264 digital video signal transmission, including embedded audio and supports input resolution up to 1920 x 1080 60fps. The SDI standard provides a nominal 2.970 Gbit/s interface specifically suited for applications such as in-vehicle, broadcasting, and surveillance.

Extended Temperature

AVerMedia delivers extended temperature solutions capable of withstanding extreme environmental conditions without compromising functionality. The extended temperature capture card line operates within temperature ranges of -40°C to 85°C (-40°F to 185°F). The thermally robust product line is specifically designed to provide greater flexibility for rugged and industrial applications, including: medical, industrial automation, factory automation, in-vehicle, and more.

AVerMedia guarantees that our products are made in accordance with the highest standards, ensuring a wide temperature range, design compactness, durability, high performance, and extended life cycles. Our design and testing procedures meet these requirement through the use of extended-temperature-grade components, onboard soldering of critical components, detailed engineering designs for wide temperature ranges, and certified testing under harsh conditions.

Dual Data Output Formats

CM313BW Mini PCIe video capture card supports real time mega pixel video images from any standard 3G-SDI onto a computer. Enabling professionals real-time streaming, video production and post production of live uncompressed 8-bit SDI SD-, HD- and 3G-SDI capturing up to 1920 x 1080. Featuring dual data output formats, the CM313BW can simultaneously uncompressed raw data and compress H.264 HW TS maintaining a low CPU loading.
