The Somfy Protexiom Advanced is a complete, wireless alarm system. The set consists of a control panel, central hub, NFC tag, siren, and a remote control, as well as 2 magnetic contacts and 2 motion detectors. All elements have been pre-programmed to immediately communicate with each other. You can control the system via your smartphone, tablet, and pc, or via the control panel and the NFC tag. You can link up to 4 persons to the alarm system who'll receive a notification in case the system detects something, allowing them to take action straight away. The central hub has a SIM card slot, which you can use for added security. In case of a power failure (causing your internet connection to drop), the system will switch to the SIM card, but this does come with subscription fees. You can pre-program 3 different security areas. You can choose to switch on only the ground floor alarm when you're sleeping upstairs, for example.
