Yohsuke Yukishita has Home Streamer (iTunes Link) for the iPhone, iPod Touch, and iPad in the iTunes App Store for FREE (regularly $2.99) for a limited time. This deal expires February 7, 2015.

Home Streamer lets you remotely view your iPhone’s camera and microphone remotely. Just open the URL shown on the app and it’s done! All you need is just a modern web browser (Internet Explorer not supported). There is NO need of extra app, sign-up or browser-plugins. You can browse the camera and microphone from the same network or an external network. External network access is highly dependent of your network environment.
