Alexa has a secret new superpower: Transforming into a security camera

Beneath the mild-mannered facade of a regular, everyday voice assistant, Alexa has an alter-ego -- a crime-fighter, you could say -- that can be summoned with the flip of a toggle found deep within your Amazon Echo Show's device settings. The setting is called Home Monitoring and it can transform your otherwise milquetoast smart display into a bad-guy halting security camera. (Bad guys not included.)
