Approximately 350,000 Ring doorbells sold in the North American markets are subject to a safety recall issued yesterday. Specifically, improperly installed 2nd-generation Ring doorbells can catch fire, causing property damage and potential burn hazards. This is a fairly unusual recall, however—and one that doesn't require consumers to return their devices.
