You're on the go. But what's happening at home? The Gigaset elements alarm system keeps you reliably informed. A glance at your smartphone is all it takes to stay updated. The elements alarm system S includes the base station "base," the door sensor "door," and the alarm siren "siren." This ensures perfect monitoring of your home's entrance area. When your front door is opened, you receive a notification on your smartphone via the free Gigaset elements app. If the door is forced open, the siren of the door sensor "door" will sound an alarm—regardless of whether the alarm mode is activated or not. A loud, deterrent noise of 100 decibels will sound, which is as loud as a jackhammer. The alarm mode can be activated or deactivated through the app. Included in the package are the base station that connects the individual sensors to your smartphone, as well as the Gigaset elements app. Additionally, the package includes free cloud service that connects your smartphone to your home and keeps your system components up to date with updates. The system can be expanded at any time with additional sensors.
