Absolutely pointless app. Detects the person after a long delay! By this time the burglary would have happened and their escape the notification would appear. Not worth paying £32 a month when the app is rubbish. It needs major improvements as all the common issues are not being resolved hence the 1 star. The app has had to be uninstalled and reinstalled on numerous occasions and the same issues continues! My children have made fun of it. Told me to get a new quality system with a good app.
