2255

Model 2255

Model 2255 captures uncompressed frames from four NTSC or PAL video sources and sends them over USB 2.0 to a host computer. Frames are captured simultaneously from all channels. The maximum aggregate rate in full resolution color mode is 60/50 fps (NTSC/PAL), yielding a per-channel NTSC capture frame rate of 30 fps for 2 channels, or 15 fps for four channels. In monochrome and/or scaled down modes all four channels can capture at full frame rate.

Model 2257 is functionally identical to the 2255 except for input types: Model 2255 has four composite video inputs whereas Model 2257 has two S-Video and two composite inputs.
