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. The sound transmission channel is configured to allow sound waves transmitted through the microphone aperture 716 and the hydrophobic membrane to be coupled to the sound input region of the microphone without exposing the sound input region to damaging pressures due to environmental impacts on the doorbell camera 106.
