The video doorbell is a recent object - the Ring, created by Jamie Siminoff, reached the market in 2013, with Google's Nest Hello following later - and the argument about it has always been about what else is in the frame. The device wakes when a visitor presses the button, or when its motion sensor detects someone approaching, then streams HD infrared video and two-way audio to a phone anywhere in the world; some models will unlock a connected smart lock remotely. That combination is both the appeal and the complaint, because a camera pointed permanently at a doorstep is also pointed at a pavement and a neighbour's path. The security record has not helped. In 2016, researchers at Pen Test Partners showed that an attacker could unscrew a Ring unit from the wall, press its setup button and reach a configuration URL that exposed the household's wireless network. The same year, a database mix-up let Ring users watch live footage from complete strangers' front porches.
