Use your iPhone or iPod as a wireless network camera. Place your iOS device anywhere you want and access its camera using a webbrowser installed on any computer in the same network.
With the integrated password protection you can block unwanted access to your Wireless Webcamera. If you want to allow public access to your camera, there's the public mode that removes all administration options from the interface. And if you do need it anymore, you can shutdown the camera from your computer using the built-in remote shutdown functionality. But there's more, use the motion detection feature to save pictures to your device whenever something moves.
