Good system GARBAGE app! I'd give zero stars. The system installed in the house is decent. Not over-the-top fantastic but decent . . . it works. The APP however is one of the worst I've ever dealt with for this type of interface. Constant app crashes, difficulties pulling up live video, even when connected to the same 100+ MBPS internet connection the security system is connected to! Just unacceptable from a "tech" company that's supposed to be on the leading edge of home security technology
