YI Dome Camera 1080p Defect

On March 11, 2020, I bought the camera “YI Dome Camera 1080p” on the website “Mercado Livre”, in Brazil.
However, since July the camera stopped moving properly, it does not move up and down, it only moves to the sides.
I have already reset to factory defaults several times and it didn’t work out.
Once in a while her image is all black.
I was sad because the camera has little use and is already defective, so it is useless to me.
The seller who sold me the camera does not want to give me another one because he said that the warranty is only 90 days, I want to know if YI can help me solve my problem?

Hi Renan, I’m very sorry, but we don’t offer a warranty for products purchased from Mercado Livre.

hi Kami Mark,
okay, but i would like some help to try to solve the problem, i am very disappointed with the YI brand.
I would like help for example changing the firmware or something similar, I just need help to solve the problem of the camera that lasted 120 days.

Hey Renan, have you tried resetting the camera? Here’s a video below walking through how to do that.
