Abstract:
1. A system for determining whether a resident of a home is inactive within the home or away from the home, comprising: at least one motion sensor positioned to detect a first activity and to transmit a first signal indicative of the first activity and a signal processor for processing the first activity signal; at least one exterior door sensor positioned to detect motion of an exterior door of the home and to transmit a second signal indicative of the motion; and a monitoring center in communication with the at least one motion sensor and the at least one exterior door sensor, wherein the monitoring center is adapted to determine whether a resident of the home is inactive within the home or is away from the home based upon the timing of the first signal relative to the second signal wherein the at least one motion sensor comprises a timer adapted to run a pre-selected time period after the detection of the first activity.
