The iSmartAlarm is a DIY, self-monitored, self-controlled home security system, with no monthly fees and no contracts required. It is controlled from an app that allows users to utilize their iPhone^® or Android™ to rename devices, monitor their home, and arm/disarm their security system at any time, from anywhere, in real-time; the app shows who is at home, when family members have left or returned, and the on/off status of each sensor. The app will alert all designated members with a phone call, SMS message, push notifications or email when the iSmartAlarm security system detects a break-in or unauthorized activity.
