We put a lot of effort to try to make YS6 secure. All information sent or received from the central unit and the sensors is encrypted. All information sent to our server will be rejected if it is not in a specific format. If the central unit is disconnected for any reasons, its internal battery can last for approx. [24] hours and a disconnect alert will be sent. The presence of all sensors is constantly checked by the central unit and an alert will be sent if the central unit stops receiving the ‘heartbeat’ of any sensor.
