Vivint Streety App

Streety App allows neighbors to share security camera live feeds and recorded video. It's available on iOS and Android.

Streety is a free app that is extending smart home security out into the neighborhood.

You can choose which cameras do you share. You can also select which neighbors have access to your cameras.
Neighbors can ask questions and post messages and videos to resolve any security issues.

Vivint is only activating the feature for outdoor cameras not for indoor ones.
