A camera controller is configured to control a camera through voice commands. The camera controller includes drain mechanisms that allow the camera controller to be used in environments in which the camera controller is exposed to fluids. The camera controller device comprises a housing body with an outer surface including a first opening and a second opening. A first channel extends from the first opening into the housing body and to a cavity in which a microphone is located, enabling audio signals entering the first opening to be captured by the microphone. A membrane is located between the first channel and the microphone to create a waterproof seal over the microphone. A second channel extends from the first channel to the second opening to create a drain such that fluid entering from the first opening can flow from the first channel through the second channel and out the second opening.
