It is possible to extend the pack by other detectors (motion, smoke, gas, vibration).

When the device is connected to the public internet, current status and alerts are available from anywhere and can be displayed on mobile phones, tablets, notebooks... Even the free portal displays graphs and sends E-mail alerts/alarms when doors are opened / connectors are disconnected. Portal will alert you also when an internet connection with a device is lost or an external sensor is disconnected.
