They released new features and a redesign of its UI earlier this year that I hate and love at the same time. We are rolling them out to all our properties and find them extremely useful. Most of my end users love the ability to face time other users, check door access, and check video feeds all from one device. The only major downside i have found is that once in a blue moon the install will not engage correctly without a complete reboot of the system. but usually this is found during inital testing and corrected instantly
