Yi Dome 1080 not staying connected and emitting loud noises

I have had my Yi Dome 1080 cameras for less than 6 months. Up until recently they worked perfectly. I am finding i cannot use them at all because 1) they will not stay connected. Go offline constantly. I have deleted and re/added and reset several times. 2) They start emitting a loud squealing/buzzing sound that is super annoying right before they go offline. The only way to make it stop is to unplug it. Please help as I am Very unhappy with these products at the moment . Thanks!

Hey @Jackiek829 Thank you for reaching out and welcome to the forum! We are glad to have you around :slight_smile: im sorry to hear that you are having connection issues and sometimes a squealing/buzzing sound. That is frustrating.

Where did you purchase the cameras from?
When they emit this sound, is it coming from the camera hardware or your live feed in the app?
Are you using 2.4ghz or 5ghz for your wifi router?
How far away from the router are the cameras?
How many walls in between the cameras and router?
What are those walls made of?

Many thanks for your assistance to get this resovled. I look forward to your response!
