Introduction This series of 4G smart hardware products can collect local device data including running status and faults and interwork with Inovance’s Internet of Things (IoT) server using 4G, Wi‑Fi, or Ethernet to enable remote commissioning and maintenance functions. Users can access the web server to monitor status and analyze faults of local devices.
Inovance has taken necessary technical measures to ensure data security. However, network risks (such as hacking) that Inovance cannot control may still exist, and Inovance is not responsible for losses caused by such network risks.
