1. A camera device comprising:
a camera;
a passive infrared sensor;
one or more processors;
one or more computer readable media containing computer executable instructions that, when executed by the one or more processors, cause the camera device to perform operations comprising
determining that the passive infrared sensor has detected first motion,
based on the determining that the passive infrared sensor has detected first motion,
initiating, by the camera device, execution of a motion verification process that analyzes frames captured by the camera for pixel differences, and
initiating, by the camera device, execution of a classification process that analyzes frames captured by the camera utilizing a machine learning model,
determining, based on the motion verification process, that the first motion is not verified; and
terminating, based on the determining that the first motion is not verified, execution of the classification process prior to completion of the classification process.
