From the developer: Visec is a software program that turns your computer into a Powerful Video Surveillance System. With Visec, users only need a PC and an inexpensive Web cam. No other hardware is required. Visec can monitor a room and record video on a user's computer when motion is detected. Visec uses powerful algorithmic software based motion detection, eliminating the need to buy any hardware. When motion is detected, (such as a burglar?s movement) Visec's alert system will e-mail you a picture of the motion that was detected, to a cell phone, PDA, or computer. Like a traditional surveillance system, Visec's video history feature allows you to playback surveillance during specified times such as when you're away from home or out of the office. Visec features Remote Live Access allowing you to see a live view of your home or office anywhere in the world you have Internet access. Additionally, you can also view recorded video from previous days. Visec also includes Stealth Mode, where the program can operate secretly on a PC, even if the PC is in use. Designed for both consumers and professionals, Visec's remote video is also PDA friendly on the Palm, Pocket PC, and WAP phones. Visec supports multiple USB cameras, and regular RCA cameras. Internet Access is not required, but Internet access greatly enhances the features.
