If Blindsight is operating but cannot see due insufficient light or mud on the sensor, the in-cab alert status light will turn yellow to notify the operator, and a camera darkness event will be logged.

Machine's operating at night, or underground in low light areas will likely generate camera darkness events.

Check for mud, dirt or anything that would block the camera's vision.

Go to Manage > Devices > Open the device > Configuration > Alert Zones

Toggle through each sensor to confirm there is nothing obstructing the cameras vision.

Confirm what time the camera darkness event was logged, and if there would have been sufficient lighting at that time.
