Vivint tech stack
Vivint's Doorbell Camera is a minimalist doorbell and front door camera that allows for 2-way talk with visitors via Vivint's smartphone app. More useful than a regular doorbell, and more subtle than a security camera, it's the best of both worlds.
Vivint Ping Camera is an indoor camera that lets you call in and out with one touch. Two-way talk connects you directly to your family from your mobile device while you’re out. You can make sure the kids started their homework, or they can contact you when they’re done. It integrates flawlessly with a Vivint Smart Home System.
