Blurry or low-resolution video on the battery Google Nest Doorbell is usually the video quality setting or a weak wifi link, not the camera. In Google Home open the doorbell's settings, go to Video and choose the highest quality your connection can carry. Check the sticker or film over the lens is gone, wipe the lens, then watch the signal strength. Quality drops on slow links: on a cellular-class connection the stream can fall as far as 720p, and lower still on a very slow one. Check that the doorbell's firmware is current, since an update in July 2024 fixed a bug that left some doorbells stuck on low resolution.
