If the first set value is less than the second set value, internal components may be rusted or condensation may occur due to moisture, so that the display unit 120 is controlled to indicate that it is in a state of caution. If the second set value is higher than the second set value, not only internal component damage but also severe condensation may occur, so that the display unit 120 is controlled to be in a dangerous state.

For example, the display unit 120 may control the display unit 120 to display a green color so as to indicate that the humidity value measured by the humidity sensor 110 is less than 10%, that is, when the humidity value is less than the first set value . The display unit 120 displays an orange color to indicate that the humidity value measured by the humidity sensor 110 is in a caution state when the humidity value is 10% or more and less than 20%, that is, the first set value is less than the second set value. . If the humidity value measured by the humidity sensor 110 is more than 20%, that is, the second set value or more, the display unit 120 may control the red color to indicate a dangerous state.

Meanwhile, the controller 140 controls the heater 130 to operate to prevent condensation when the humidity measured by the humidity sensor 110 is equal to or higher than a first set value (for example, 10% or more).

As described above, according to the present invention, it is possible to effectively prevent condensation of a waterproof camera to protect internal components of the camera, and also to eliminate the phenomenon that condensation is generated and imaging is not possible or image blurring is generated .
