Motion
Detection
The 2251 performs motion detection in three user programmable regions of
interest. For each separate region of interest, the user can set up different motion detection sensitivity.
Within the regions of interest motion can be further localized to a 16x16
pixel block.
Please see images below.
For a functionally equivalent product with
enclosure, please see our Model 2250 for details.
Software and Instruction Manual
The 2251 was designed primarily for OEMs who integrate it with their
application software using the Software Development Kit (SDK) available for download
below. The SDK supports simultaneous preview and recording, snapshot
feature, OSD. A fully functional demo application (with the source code)
illustrates the use of the SDK. A JPEG capture demo application illustrates
the simple frame grabbing function.
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 knowledge of C or
Visual Basic. It is not a consumer product intended for home use.
The SDK
includes three demo applications provided with the source code:
App 2251
demo, a MFC
application, that allows:
1. Video stream preview in the window
2. Modification of compression, audio and
video setting
3. Recording the stream to the hard drive
MotionJPEG Demo, a simple console
application, records a given number of JPEG frames to the hard drive without
display.
Visual Basic Demo
A Visual Basic 6.0 demonstration program is available for downloading. It
shows how to communicate with the 2251 but it does not implement every
function.
