Sensoray announced the newest addition to their USB video capture line of products, the 2251. The 2251 provides MPEG and JPEG video compression to Linux and Windows computers via a high speed USB connection. The Model 2251 USB frame grabber accepts an NTSC or PAL composite analog video source and converts it into an MPEG stream along with the optional synchronized audio.

Model 2251 is software compatible to model 2250. The only exception is the lack of a microphone input on the 2251. All other features work exactly the same. There is no separate software for model 2251, the regular 2250 SDKs should be used. The SDK supports simultaneous preview and recording, snapshot feature, OSD. A fully functional demo application illustrates the use of the SDK.

The 2251 accepts an NTSC or PAL composite analog video source. Adjustable resolution and bitrate selections allow the user to define their quality and storage requirements. Sensoray includes a Software Development Kit, SDK, with all of their 2251’s with support for Linux and Windows based computers. The included SDK supports multiple units per computer. The 2251 is available immediately with pricing starting at $226. Quantity price breaks are available.

Motion Detection Future: The 2251 supports motion detection in three user programmable regions of interest. For each separate region of interest, the user can set up different levels of motion detection sensitivity. Within each of the regions of interest, motion can be further localized to a 16x16 pixel block. Synchronous Audio: The 2251 supports synchronous audio capture from a line level input.

Currently, the 2251 driver does not support seamless integration with any 3rd party applications (such as Video LAN, or Windows Media Encoder). The functions of the 2251 without software development are limited to those of the demo applications in the SDK. This product requires a knowledge of C-language or Visual Basic. It is not a consumer product intended for home use.
