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. 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.alarm companies atlanta
Pros:The daytime video on this thing is excellent and the color night vision is phenomenal. Physical set up was a breeze. Our existing doorbell was mounted to the brick and mortar wall, and Skybell's bracket matched up perfectly with the existing holes, so no drilling. Had I needed to though, it comes with the proper drill bit to do so. I do have to ding them for the mounting screw. It is plastic and stripped almost immediately so I had to finish tightening it with some needle nose pliers.
