A system for detecting mounting of a card skimmer at an automated teller machine receives detection data from sensors. The system converts the detection data from the time domain to the frequency domain using a wavelet transform to generate a wavelet matrix of coefficients. The system includes a convolutional neural network model to identify features in the wavelet matrix. The system generates a rain alert signal based on the identified features. The system includes a long short-term memory recurrent neural network model to determine a sequence of (i) an idle state, (ii) a hand approach state, and (iii) a card skimmer mounting state based on the detection data. The system generates a tamper alert signal based on the sequence determination.
