The W20 is a powerful alarm that supports Wi-Fi, GSM and GRPS wireless communication technology. It is compatible with a wide range of security systems such as door and window sensors or security cameras, but it can also react to various other risks, including fires or break-ins. If a threat is detected, it immediately alerts the owner via phone, SMS and app. The minimalist design of the device has soft rounded edges and the narrow LED display on the surface gives it a technical feel.
