Abstract: A monitoring and detection system that continually monitors a person(s) presence passing through areas such as rooms, homes, buildings and the like. The system can include multiple operating modes such as a home mode for greeting visitors and normal facility users as well as a secure mode for protecting the facility and occupants from intruders. The novel system provides for multi-task control of all electrical functions in a home such as air conditioning, lights, power and the like. The system can operate events via completely timed static events(i.e. for preselected time periods). The invention can also be used to activate or deactivate events through sensor detection. The preferred embodiment uses ultrasonic sweep sensors which can be programmed to automatically detect person(s) animal(s) that cross protected areas over certain times of the day, week, month based on different conditions, as well as dry contact sensors such as contact switches for doors and windows and the like.
