The recording duration can be set for up to 90 seconds but if continuous motion is detected another recording will engage immediately. The basic free plan comes with a 7 day recording history or up to 1gb. They offer other plans for a fee that allow the expansion of the system for more cameras and more recording space for a longer period of time.
iPhone setup is integrated into the setup of the device in general. Total setup time is about 10 minutes for the base station and app, as well as the initial camera setup. It's very easy to do, the directions are great and there are video tutorials available if needed.
