PCIe Video Frame Grabbers
Power consumption: CL311-M2 4.6 W; CL312H1 16 W. Resolution and channel-count combinations are model-specific.
AVerMedia’s NDAA-compliant PCIe frame grabbers provide video acquisition across analog and HDMI source formats. CL311-M2 combines Full HD HDMI capture with composite, S-Video and component inputs. CL511HN delivers single-channel 4K60 HDMI capture with HDR capability and power-off pass-through.
CL312H1 provides two HDMI channels, and CL314H1 offers four-channel 1080p60 or two-channel 4K30 recording. Hardware scaling, de-interlacing and color-space conversion reduce host processing requirements. Low-profile designs accommodate compact computers, with the model selected around source format, channel count and recording resolution.
