The 'iSmartAlarm' contact sensor is a multipurpose security solution for consumers who are looking to DIY their own alarm system instead of signing up for professional monitoring services. The device works by being positioned onto your choice of doorway, window or cabinet (depending on the sensor) and will immediately go to work monitoring for any openings to send off an alert as soon as it detects an event. This will activate an alarm that will warn intruders that they have been detected and also work to alert anyone who might be inside that an entryway has been breached.
The 'iSmartAlarm' contact sensor can be set up for use with multiple units on the same system and will automatically send a notification to the administrator's device as soon as an event is logged.
