Basically you set up a network based camera in the kids room and fire up BabyCam to watch the live video stream.
NOTE! You absolutely need an IP camera for BabyCam to work. It is not enough to purchase the app.
The camera works over cabled or wireless network, and can be turned in order to cover the whole room. The camera also has a IR filter which means it can stream a good picture even when it is dark in the room.
BabyCam is created with simplicity of use in mind, and will automatically find the camera on your network. All you have to do is connect the power cable to the camera to turn it on, and start the app on your iPhone or iPad.
Both of this applications are designed to work together as well as indepently. A typical situation is that you configure your iPad to show all your video streams, and keep the iPad in your living room.
With the iPhone application you can move around your home and still have access to the video cameras.
Wherever you are within your network, you have full control.
