Four-Channel Frame Grabber Handles 60 fps

Aiming at the need for a multichannel, low-latency, USB video capture device, the Model 2255 four-channel frame grabber from Sensoray boasts a total capture rate of 60 frames/s (fps). As a result, it can capture four composite NTSC or PAL video sources at 15 fps or two channels at 30 fps. Full frame rate capture is possible across all channels simultaneously using monochrome or scaled-down modes. The supplied software development kit contains the drivers for Linux and Windows, the application programming interface (API), and a demo program that illustrates the use of the API. The driver supports multiple units, permitting easy system expansion and integration.

The device accommodates a variety of formats, eliminating the need for format conversions in a wide range of applications. Supported formats include:

o RGB packed (24 bits/pixel, bitmap compatible) o YCrCb packed (16 bits/pixel, YUY2 compatible) o YCrCb planar (16 bits/pixel, optimal for image processing) o Y8 (8 bits/pixel, monochrome)

The Model 2255 is powered through the USB 2.0 connection on a PC, so there is no need for an external power supply.


Contact the company for availability information.


The Model 2255 costs $515 for a single unit.
