An analytics device (200) for monitoring maintenance on an elevator system performed by an individual including: a processor (282); and a memory (284) including computer-executable instructions that, when executed by the processor (282), cause the processor (282) to perform operations, the operations including: capturing a first video stream (310) using a first video camera (490a-d); extracting sequences from at least the first video stream (310); extracting features from the sequences; and analyzing, using a long short-term memory model, the sequence to determine whether the maintenance performed on the elevator system by the individual is performed correctly; wherein the long short-term memory model is trained by: obtaining training videos of individuals performing maintenance activities; labeling the training videos; extracting frames and clips from the training videos; extracting sequences from the frames and clips; and extracting features from the sequences to produce the long short-term memory model.
