Is the SIERA.AI Safety System S3 dependent upon a WiFi signal to operate? If the WiFi goes down, how does that affect the system?

The S3 operates comfortably without WiFi however data reporting, and over-the-air software updates may be affected.

The system does not depend upon a network signal to operate.  The S3 comes pre-enabled with Cellular data connectivity. In case your devices are not purchased with cellular data enabled or cellular connectivity is not available in your facilities, S3 will rely on WiFi to transmit data.

In a nutshell, S3 needs the WiFi or cellular connection to stream data to the cloud dashboard for analytics but that does not affect safety/operation.
