Zero Stars. Things That Don't Work: Push notifications (in app "alerts" tab always empty, no 30 second video clips as advertised with camera system when purchased), Email notifications will stop working May 30 (Google imposed termination of "less secure log-in"), customer service/support/feedback, quick access to live feeds when notification is sent (disruptive, offensive, inappropriate ads that might as well be called ransom demands for the security this product is supposed to provide).
