“The doorbell’s camera was uploading facial recognition data from the camera to Eufy’s cloud servers with identifiable information attached, and that this data wasn’t actually removed from Eufy’s servers when the related footage had been deleted from the Eufy app. In the video below, Moore also notes that Eufy used the facial recognition data from two different cameras on two completely different accounts to link data from each, and points out that Eufy never notifies the user that this is happening – the company’s market rather implies just the opposite.”
