Eye Spy FX (PC & Mac) This software works on Windows and Mac and has a mobile viewer that can be accessed on a handful of devices, including the i Phone. The software, while primitive, does a good job with privacy; the only way to access your stream is with your camera's special PIN.

Webcam no cost free no sign up or membership
It can also be set up not only to send you an e-mail if it detects motion but also send a note to a Twitter account and upload whatever footage it's captured to You Tube or Daily Motion.
There is quite a bit of setup involved though, and the wizard that walks you through it is bound to overwhelm the average user.
Software can offer a definite piece of mind over browser-based solutions.
Most of these apps can run quietly in the background, and can save footage to your hard drive for archiving.

Honorable mention: If you're willing to shell out , you can go with Mac-only Evo Cam, which I've heard good things about.
It does motion capturing, e-mails, and offers mobile access.
The app does an exceptional job at letting you pick various ways you want to be notified.
