The Microphones That May Be Hidden in Your Home

Google apologized Wednesday to customers who purchased its Nest Secure home-security system. The device is equipped with a microphone that has gone unmentioned since it went up for sale in 2017. Earlier in February, Google announced on Twitter an upcoming software update that activated the microphone, making the Nest Guard responsive to voice commands and Google Assistant technology. The tweet startled users, who were never told the system could pick up sound. "Have I had a device with a hidden microphone in my house this entire time?" one user asked.
