Christmas Motion Detection is an application that saves still pictures and/or makes .avi files when anything in motion is detected in front of the selected webcam. The pictures and the frames of the movies are timestamped.
- AVI files (using Video for Windows, interop library is included);
- Updating JPEG from internet cameras;
- MJPEG (motion JPEG) streams from different internet cameras;
- MMS stream - Microsoft Media Services;
-
Local capture device (USB cameras or other capture devices, DirectShow interop library is included).
