The Nano SPY LINK gateway is the heart of the Nano SPY solution. The Link is connected to the internet and the MySirius Cloud solution or local server installation via WiFi, Ethernet or Power Over Ethernet (POE). The Nano SPY data loggers are connected to the Link wirelessly (2.4 GHz). In case of power failure, the internal battery ensures that it remains active for another 4 hours (Ethernet version). The wireless range is +/- 40 metres around the Link. With a RELAY/ALARM unit, this range can be doubled. Optionally, the Link is equipped with Bluetooth (BLE) communication. This feature allows you to view the status of all your system, even if the internet is (temporarily) unavailable. Supplied with mains power supply and network cable (3 metres).
