Description
The Dinsafer Helio-A4S-4G is a compact, fully wireless smart security system designed for residential installations. It runs on a Freescale ARM Cortex-A7 processor and communicates over LAN, Wi-Fi, and 4G cellular, giving it reliable connectivity indoors and outdoors.
Beyond intrusion detection, the system functions as a home-automation hub: it integrates with IP cameras, smart lamps, and heating devices, and is managed entirely through a free iOS or Android app. The built-in RFID module allows simple operation for children and older users.
