2K resolution smart TV doorbell, smartphone compatible. - Brand: SwitchBot - Model Name: Smart TV Doorbell - Resolution: 2K - Features: Smartphone compatible, with monitor Thank you for viewing. I purchased this to use as a doorbell at home, but the distance from my Wi-Fi-enabled home to the front door was too great, resulting in unstable communication. Therefore, I have decided to sell it and use a different doorbell. I used it for about a week, but I don't think there are any noticeable stains or marks. The accessories are almost unused.
