It is not the SkyBell HD making the buzzing sound; what you hear is the transformer installed in your home.
If your transformer is buzzing it means that your transformer isn't able to produce enough power for the SkyBell HD.
The transformer must be providing 16v or greater in order to power the SkyBell HD.
If you have a mechanical (ding-dong) chime:
- Open the SkyBell app and go to the Device Settings.
- Tap on Indoor Chime and confirm the Digital Door Chime is toggled to the OFF position. If it is toggled to the on position, please wait a couple of minutes after turning it off then press the SkyBell HD button to confirm that the 2 plungers in the chime hit their plates normally and the buzzing has disappeared.
If you have an electronic/digital chime you must have a Digital Doorbell Adapter and the Digital Door Chime should be toggled to the ON position.
Occasionally, some of the older door chimes do not regulate the power current to the SkyBell properly, which could cause a buzzing or humming noise. If you replace the door chime this issue will be resolved. If you replace your door chime with a digital door chime please make sure you get a SkyBell digital door adapter.
