Blindsight does not require 3/4G connection to operate the AI and local alerts. Should 3/4G not be available, the BPU status light will indicate this with a slow flashing green light.
If no 3/4G is available, Blindsight cannot send or receive data from the cloud, which means that it cannot be (re)configured, send detection logs and videos, and receive over-the-air updates.
Blindsight stores all detection data onboard in a rolling log, and uploads to the cloud when a 3/4G connection is established.
