A controller is provided for coordinated control of various subsystems, such as a heating, ventilation, and air conditioning (HVAC) subsystem, a camera subsystem, and a security subsystem, in a structure such as a home, by allowing automatic as well as manual changes to be made to the subsystems within their respective constraints. The controller may change the states or settings of the subsystems automatically upon occurrences of certain conditions, or allow the user to change them by switching a structure mode for the subsystems between a home mode and an away mode. A change in the structure mode may effect changes to some or all of the states or settings for some or all of the subsystems.
