Ive had my doorbell for about a year now with minimal issues but just recently ive been experiencing an issue where the doorbell will make a buzzing almost alarm noise that occurs constantly after the first detection. A power cycle will fix the issue only until the next motion recording. I assumed it was some sort of alert setting or soemthing but i cant seem to find any settings out of place. It is clearly tied to the activity of the camera as the distortion and tone frequency is tied to if its recording at the moment. Id post video but the files are too large. Any help is appreciated.
These are the first questions that come to mind:
- Is Chime Controller installed?
- If so, then how was it wired?
- What kind of chime do you have?
- What tools do you have available for testing? (In other words, do you have a multimeter and know how to use that?)
If you can share photos of the buzzing chime and how it’s wired, that might be helpful, too.
I do have a chime controller wired but its worth noting that the buzzing is only coming from the doorbell cam itself not the chime indoor. The buzz is not constant either its a tone for about 100 ms followed by a silent gap for about 1.5-2s. this gap and the sound of the tone are different if the camera is motion detected or not. I’ll see if i can find a good way to post video. Might have to gyazo or google drive it since its so big. Chime is mechanical and I have a multimeter I know my way around. I’ll see if I can find the exact chime model #.
Here’s links to the video of the chime making noise.

This is the chime I am using:
Yeah, I think that’s the key piece of information that makes my previous questions irrelevant. I was thinking that this might’ve been headed into one of those “phantom” buzz/hum/ring situations with an improperly wired chime and/or mis-wired or absent Chime Controller. This is why it’s good to ask, I guess, and you answered a question that I didn’t even ask! 
That is weird! I don’t know why it’s doing that. What did Support say when you contacted them?

In that discussion, it seems to be an issue with an Alexa/Echo connection causing unexpected/unwanted sounds from a Video Doorbell Pro and Duo Cam Doorbell. I’m not sure if that’s relevant to your situation. Do you use Alexa and have the Video Doorbell v2 connected to that?
Crease, I use alexa for two things. The device notifications to an echo in my kitchen and a routine on person detection to open the camera feed on an echo show in my office. Removing the routines but leaving the notifications on has seemed to resolve the issue. I’m not sure what has changed as I have been using it like this for a year now but I am inclined to blame alexa as I have had similar issues with their interface in the past breaking for no reason. I just got home assistant running at my house so I might try and use that as a mediator to take detections from the doorbell and pass them to my alexa devices. Either way thanks for the help Crease!!

Hey, cool! I’m glad that pointed you in the right direction, because I really wasn’t sure if it was related or not, but it was the one recent thing I read that came to mind.
I’ve been a Google Home user for years and have added Alexa to the mix for only the past year and a half, but both of those platforms tend to change things periodically in a way that causes problems with third-party integrations here and there. I keep thinking more and more about Home Assistant—and have read about it some because of what other Forum users have written—but haven’t yet set aside the time and resources to really get into it. I hope you’re able to make that work in the way you want!
