Home Camera (PC) This software runs a streaming video client that can be accessed from any computer with a browser.
You can view either live video or snapshots that can be taken at intervals or on-demand.
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.
It also supposedly keeps an online and offline archive of your footage, although I couldn't get either to work.
While this "pro" plan is free during Ugolog's beta period, the eventual free plan drops that storage down to 100MB per month.
