AVerMedia’s NDAA-compliant M.2 frame grabbers provide HDMI and SDI video acquisition for compact embedded computers. CN311-H captures a single HDMI source at up to 4K30. CN312SW offers dual SDI inputs, and the CN312M family combines one HDMI and one SDI input, with 1080p60 recording on the dual-channel models.
Hardware scaling and color-space conversion reduce host-side video-processing work. CN312SC adds conformal coating to the CN312S offering, and CN312M is available in normal, extended-temperature and conformally coated variants. These options allow the card to be selected around the video source, host interface and environmental requirements.
