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. In some implementations, the speaker may also adopt a sound input region offset from the speaker openings 718 and a respective hydrophobic membrane to block water intrusion while allowing transmission of sound waves from the speaker openings 718 to the sound input region of the speaker. More details of some examples of waterproof microphones and speakers are discussed in U. S. patent application Ser. No. Attorney Docket No. 104248 5227 US, filed , 2017, entitled “Systems and Methods of Presenting Appropriate Actions for Responding to a Visitor to a Smart Home Environment,” each of which is hereby incorporated by reference in its entirety. A smart home environment is created at a venue by integrating a plurality of smart devices, including intelligent, multi sensing, network connected electronic devices, seamlessly with each other in a local area network and/or with a central server or a cloud computing system to provide a variety of useful smart home functions. Nowadays, network connected video surveillance cameras have been extensively used in the smart home environment to provide video monitoring and security. Such extensive usage of video cameras in residential and commercial environments has increased substantially, in part due to lower prices and simplicity of deployment.
