“We should definitely be concerned about this surveillance network that is being built, this public safety infrastructure that is being built, that isn’t going through a full proper process,” Maass says. The Ring Doorbell makes it easy to know who is at your door at any given time. And if you don't have your mobile device nearby to check for alerts, you can easily ask Alexa to let you know. All models of the Ring Video Doorbell are compatible with both the Amazon Echo Show and the Amazon Echo Spot—the two smart displays made by Amazon. The Ring Doorbell is also compatible with Amazon Echo Dot. If someone rings the doorbell, Alexa will make an announcement.
