An imaging apparatus includes a camera, a cover covering the camera and capable of changing reflectance of a surface thereof, and a control unit configured to control the reflectance of the surface of the cover so as to be switchable between a first mode and a second mode. The first mode causes light to reflect at the surface of the cover. The second mode causes light to pass through the cover and the reflectance in which is different from that in the first mode.

The various implementations described herein include a video camera assembly that includes: (1) a housing; (2) an image sensor encased in the housing and configured to capture activity of the smart home environment; (3) a wireless radio configured to transmit video frames captured by the image sensor to an electronic device via a remote server; (4) at least one infrared transmitter configured to selectively illuminate the smart home environment; (5) one or more circuit boards encased in the housing, the one or more circuit boards including at least one processor mounted thereon; and (6) a heating component coupled to the image sensor, the heating component configured to continuously maintain the image sensor at a temperature above a threshold temperature while the image sensor is capturing the activity of the smart home environment.

To solve the above problem, a monitoring apparatus according to an embodiment of the present invention comprises: a communication unit for receiving an original image acquired by a camera; a storage unit for storing the original image; a screen unit for displaying the original image and a corrected image obtained by dewarping the original image; and a control unit for controlling operations of the communication unit, the storage unit, and the screen unit, wherein the screen unit displays an icon in a dewarping area of the original image where the corrected image is obtained by dewarping the original image, indicates that the dewarping area is selected when the icon located in the dewarping area is selected, and displays a polygon representing the selected dewarping area.
