I recently picked up a TRENDnet TV-IP422W camera and am using IP Vision as the viewer. Watching the babys room is clean and simple whether it be at home or on the road. This app is easy to configure (assuming you know the mjpeg url for your camera) and easy to manage. Note: edited my post about pan/tilt control since that is in the Pro version of this app.
