Are you not completely sure of your internet connection or power supply at home? Pick the Honeywell Evohome HS922GPRS. The alarm system consists of a hub with GPRS, a motion sensor, a door and window sensor, a tag reader with integrated siren, 2 tags, and a SIM card. If you install the free app on your smartphone and tablet, the system will send a notification to your phone straight away when it detects something, no matter where you
are. Should there be a power outage, or should your internet connection drop, you'll receive an SMS message and an email thanks to the included SIM card. The standard package is suitable for an apartment and for smaller homes. You can expand the system with up to 32 elements, customizing it to your home and your security needs.
