Good basic kit to secure a minimum a house. But in reality the additional sensors are quite expensive and if we want to fully equipped house that we come at the cost of true alarms (especially in case of Internet failure alarm does not work). As against the application and that the alarm is connected allows eg whether children are home from school (with door sensor). Coupled with the additional camera kit allows viewing his remote house that is a good point. The entire installation and configuration is very easy. So a good basic kit for a limited security of a house (but considering the price of the basic package I easily forgive the faults).
