Alexa Guard Plus has three main components: First, your Echo speaker or Echo Show display will be able to listen for a wide variety of sounds, from doors opening and closing to footfalls and glass breaking. Second, your device will be able to respond, to deter would-be intruders from breaking in (by playing a recording of dogs barking, for example). And finally, your device will add an emergency line monitored 24/7 by a third-party company that will direct your calls to the police, the fire department or personal emergency contacts as appropriate.
Guard Plus will also integrate with a number of smart home security services, including those from Abode, Wyze, A3 Smart Home, Scout, Resideo and Amazon's own Ring. Ring Protect Plus subscribers will get Alexa Guard Plus for free, and each of the other services will soon introduce subscription tiers that include Guard Plus as well.
