A non-intrusive elevator monitoring device (10) in electrical connection with an electrical power system (11) and an elevator is disclosed. The elevator monitoring device (10) comprising: a receiver (12) for receiving an electrical signal, the electrical signal being power supplied to the elevator by the electrical power system (11), a sampling circuit (14) for sampling the electrical signal with a pre-defined sampling rate for obtaining a plurality of signature waveforms, the plurality of signature waveforms corresponding to varying amplitudes and time intervals and a processor (16) for processing a plurality of segments in each of the plurality of signature waveforms, the plurality of segments corresponding to a plurality of electrical parameters of the elevator. Therefore enabling monitoring and predicting maintenance of the elevators.
