From PC Private Eye:
PC Private Eye puts your PC to work while you are away. It allows the use of inexpensive Webcams for the purpose of monitoring your home or office for motion. In the event that motion is detected, PC Private Eye can be configured to send e-mail with picture attachements of the person or thing that caused the motion. PC Private Eye can also sent text pages. Another configurable option is the PC Private Eye web server. If the web server is turned on, then e-mails sent will include a url. If for example I'm at the office, and motion is detected at my front door, e-mail will notify me with picture attachments and a url to link to with my browser. When I connect with my browser I can see all recent pictures, take a current snapshot, as well as perform remote management of PC Private Eye options. PC Private Eye is also a fully functional Webcam product. Use it to set up a webcam in your home or office.
