An application device operated by infrared (IR) sensing is provided. The application device includes a camera module and an IR sensor. The camera module has a storage unit and is suitable for receiving an enable signal to activate a recording so as to produce an image data. The IR sensor is suitable for sensing whether an IR signal is interrupted, or sensing whether there is an IR radiation in a detecting area of the IR sensor. When the IR sensor senses the IR signal is interrupted or detects an IR radiation from the detecting area of the IR sensor, the IR sensor activates a switch to transmit an enable signal to the camera module so as to start recording image data into the storage unit.
