For OEM applications, the unit can be custom-ordered to include high density headers in place of the standard connectors (Model 2255-NC). Model 2255 is available as an OEM bare board (Model 2255), in a metal enclosure (Model 2255S), or mounted on a PC expansion bracket (Model 2255S-PC). Video cables must be purchased separately. CablesĪ USB cable is supplied with models 22. Hardware compression facilitates simultaneous JPEG capture at 30 fps on two channels, or on four channels at 15 fps. Linux API, which includes Video4Linux2 (V4L2) support.This is recommended only for Direct Show application development. Image buffers are allocated by the application and then registered with the driver, thereby greatly simplifying both custom application development and integration with third-party image processing software. This is recommended for most Windows applications. Sensoray offers several free, downloadable Software Development Kits (SDKs) to enable OEMs to quickly integrate Model 2255/2257 units into application systems: Models 2255/2257 are capable of performing advanced video deinterlacing to reduce motion artifacts in captured images.ĭeinterlacing is performed by hardware so that the host computer is not burdened with this task. Models 2255/2257 have exceptionally low latency, making them especially useful in applications that require fast visual feedback.
USB VIDEO GRABBER PAL 60 SERIAL NUMBER
Please refer to the 2255 software documentation for details.Įach unit has a serial number that can be read through the API, thus enabling the application software to easily identify specific units in multi-unit systems. The units support Y8 and YCrCb planar natively, while conversions to RGB and YCrCb packed formats are optionally performed by Sensoray drivers.
YCrCb planar (16 bits/pixel, optimal for image processing).
USB VIDEO GRABBER PAL 60 FULL
In monochrome and scaled-down modes all four channels can capture at full frame rates.Ī variety of output resolutions and formats are supported, eliminating the need for the application program to perform format and resolution conversions. The maximum aggregate capture rate in full resolution color mode is 60/50 fps (NTSC/PAL), yielding a per-channel NTSC capture rate of 30 fps for two channels, or 15 fps for four channels. 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. Model 2255 simultaneously captures uncompressed frames from four NTSC or PAL video sources and sends them over USB 2.0 to a host computer.
