• wherein the processor is configured to allow:
• a first image captured at a first frame rate to be received by the at least one camera;
• a human object to be detected from the first image;
• an event signal to be generated when it is detected that a product object is picked up by the human object after the human object is detected from the first image;
• and
• a second image including the human object to be acquired by controlling the at least one camera to capture the image at a second frame rate higher than the first frame rate in response to the event signal;
• payment information to be received from an external point-of-sales (POS) device through the communicator;
• information related to the detected product object to be generated;
• the second image to be converted to a third image of a third frame rate depending on whether the related information matches the payment information, the third frame rate being lower than the second frame rate;
• and
• the payment information and the third image to be stored in a database.
