Ring-like smart doorbell monitors people in Covid-19 isolation

A community in Beijing is resorting to smart doorbells similar to Amazon’s Ring to make sure people are abiding by strict self-isolation rules during the Covid-19 pandemic. The community in the city's Shijingshan district now alerts workers and sends a short video recording over an app whenever someone rings one of the doorbells, opens the door or walks past the door’s threshold. The community first received the doorbell as a donation from smartphone maker Xiaomi before buying more, the state-owned Global Times reported.
