Sensoray Co. Inc. has introduced the model 2255 USB frame grabber, a multichannel, low-latency video capture unit. The device receives data from up to four composite NTSC or PAL video sources simultaneously, with a total capture rate of 60 fps. Using all four channels provides image capture at a rate of 15 fps each. In scaled-down and monochrome modes, users may achieve the full frame rate at all four ports. The supplied software development kit contains drivers for Linux and Windows.
