The red light symbolizing the life of the personnel wearing monitors was still on, which meant their owner's life was safe and sound.
It could only detect whether a person was alive, unable to monitor more detailed information—this was a temporary technological limitation.
After all, high-volume information transmission technology had been cut off for more than four hundred years; picking it back up wasn't so easy.
Therefore, the information that could be transmitted back through sensors was limited—first, the fairly accurate life feedback, and second, the not quite real-time map location.
Logically, the red light symbolizing life should always be on... or to say, it should either be on or off without flickering.
Their research center's voltage was absolutely stable, unlikely to cause the lights to flicker due to voltage issues.
An illusion?
