Abnormal behaviour – Solving the failsafes

EYESEE Drone incorporates various mechanisms to ensure the safety of users and the integrity of the drone.

These behaviours (or failsafes) are triggered during flight. When a failsafe is triggered, the application displays a message to help you identify the cause.

Resolving the failsafe will enable you to continue your inventory safely.

EYESEE Drone incorporates 13 failsafes. Here is the list of failsafes and how to resolve them:
