1. A range hood comprising:
a main body including a bottom surface and a front surface;
a first driver assembly disposed in the main body and including a first motor and a first fan, the first motor being configured to rotate the first fan to cause air to move through an intake opening in a downward facing portion of the main body;
a first camera disposed in the bottom surface of the main body and configured to capture a first image of an upper plate of a cook top that is positioned below the main body;
a second camera disposed on the front surface of the main body and configured to capture a second image of a user;
a second driver assembly disposed in the main body and including a second motor and a second fan, the second motor being configured to rotate the second fan to cause air to move in an unenclosed free space in front of the first camera beneath the bottom surface of the main body;
a display disposed in the front surface of the main body;
a transceiver disposed in the main body; and
a processor disposed in the main body,
wherein the processor is configured to:
control the first camera to capture the first image of the upper plate of the cook top,
control the display to display a graphical user interface (GUI) for viewing the first image,
control the display to display the first image,
identify whether smoke is generated on the cook top from the first image,
based on the smoke being identified from the first image, control to absorb the smoke through the intake opening in the main body by controlling operation of the first motor that is configured to rotate the first fan to cause air to move through the intake opening in the downward facing portion of the main body,
identify whether there is fogging of the first camera from the first image,
based on the fogging of the first camera being identified from the first image, control to mitigate the fogging of the first camera by controlling operation of the second motor that is configured to rotate the second fan to cause air to move in the unenclosed free space in front of the first camera beneath the bottom surface of the main body,
based on the fogging of the first camera not being identified from the first image while controlling to mitigate the fogging of the first camera, discontinue the controlling to mitigate the fogging of the first camera,
control the second camera to capture the second image of the user, and
control the transceiver to transmit the first image to an external device,
wherein an optical axis of the first camera is inclined counterclockwise by a setting degree with reference to a virtual line extended at right angles from the upper plate of the cook top,
wherein the setting degree is obtained based on a mathematical equation as below,
equation:

OG Complex Work Unit Math
wherein the θ is the setting degree,
wherein the H is a distance from the upper plate of the cook top to the bottom surface of the range hood,
wherein the L2 is a distance from a rear surface of the range hood to the first camera of the range hood, and
wherein the L4 is a distance from a rear surface of the cook top to a front surface of the cook top.
