In one aspect of the present disclosure, a movable barrier operator system is provided that includes a motor configured to turn a drum to pay out a cable from the drum and permit a door connected to the cable to move from an open position toward a closed position. The system includes a memory configured to store an expected variable of the door, and a sensor configured to detect movement of the door. The system further includes a processor circuit operatively coupled to the motor, the memory, and the sensor. The processor circuit is configured to: use the sensor to estimate an actual variable of the door; determine whether the actual variable is acceptable based at least in part on the expected variable and the processor circuit causing the motor to turn the drum; and change operation of the movable barrier upon the actual variable of the movable barrier being unacceptable.

System and method for movable barrier monitoring

Systems, apparatuses, and methods are provided herein that may be used to monitor a movable barrier operated by a movable barrier operator. In some embodiments, a system includes a camera configured to capture frames, and a control circuit. The camera has a field of view that defines a boundary of each of the frames. The control circuit is configured to receive a first frame, identify a stationary object in the first frame, and define a region of interest 'ROI' relative to the stationary object in the first frame. The control circuit is further configured to receive a second frame, identify the stationary object in the second frame, determine whether at least a portion of the ROI is outside of the second frame, and cause the movable barrier operator to enter a failsafe mode upon the at least a portion of the ROI being outside of the second frame.

Systems and methods for monitoring a movable barrier

In one aspect, a universal receiver is provided for being operably coupled to a movable barrier operator. The universal receiver includes at least one radio antenna adapted to receive signals transmitted at different frequencies and a controller operably coupled to the at least one radio antenna. The controller is adapted to determine a code of a signal received by the at least one radio antenna at any one of the different frequencies. The controller being further adapted to learn the code in response to a user-independent learning condition being met.
