I have top tier internet connection and accessing cameras, switching from camera to camera, zooming, etc there is significant amount of lag. Also just getting to arm/disarm via app takes significant amount of time. I getting tired of the dial up like speeds of this app and now today it crashed and has been down for about an hour. Seriously what am I paying vivint for? Premium fee for dial up speed?! Also when IT is doing maintenance for vivint app, you don't have access to the app.
