Abstract

A system for analyzing a current movement of a point on a garage door can include a memory, a port, and a processor. The memory can be configured to store a profile. The profile can be produced from one or more previous movements of the point on the garage door. The port can be configured to receive, from a sensor, a signal that corresponds to the current movement of the point on the garage door. The processor can be configured to perform an analysis of the signal with respect to the profile. The processor can be configured to produce a result of the analysis.

12. The premises security system of claim 9, wherein the sensor comprises an accelerometer and the at least one previous signal corresponds to a change in a gravitational force sensed by a first axis component of the accelerometer, the first axis component being along a height of the garage door.

13. The premises security system of claim 12, wherein the at least one previous signal further corresponds to at least one other force sensed by the accelerometer, the at least one other force produced by a rotation of a shaft of a motor of a garage door opener, a rotation of a drive mechanism of the garage door opener, a vibration of a trolley of the garage door opener, a vibration of an arm of the garage door opener, a vibration of the garage door, a vibration of at least one roller of a track and roller system, a vibration of at least one track of the track and roller system, a movement of at least one spring of a counterbalance system, a movement of at least one cable of the counterbalance system, or any combination thereof.

14.
