Abstract: A computer-based system employing video capture, video motion detection, digital I/O and communications technology is applied to monitoring and security applications. Video information from one or more analog or digital cameras, is independently converted into digital form, optionally displayed in computer monitor on separate resizable windows, analyzed for motion and/or transmitted via the Internet or other networks. Motion detection or event triggers may be derived from a plurality of sources including analysis of digitized camera video signals, motion detector devices, signals from alarm systems, X10 motion sensors or cameras with built-in motion detection. Once a trigger event occurs, software compresses the digitized camera image, stores it in a local database, converts it to an Internet mail binary file format, and sends the file to the address of a recipient. Alternatively, a beeper or direct phone call may be sent in response to alarm condition.
