In some implementations, both the microphone and the speaker of the doorbell camera 106 adopt waterproof features to deter water permeation into the electronic components within the device housing 702 and cause irreversible damages to the electronic components. Specifically, the waterproof features may be integrated at the openings 716 and 718 to deter water permeation such as from a jet or stream of water impinging on at least one of the openings 716 and 718. In an example, the microphone may be disposed inside the device housing 102, and include a sound input region offset from the microphone aperture 716. A hydrophobic membrane is affixed to a first interior surface of the device housing 702 and covers the microphone aperture 716 thereon. The hydrophobic membrane is configured to allow transmission of sound waves and block water intrusion from the microphone aperture 716. A sound transmission channel couples the sound input region of the microphone to the microphone aperture 716 on the front cover plate 708.home security in houston
