# Troubleshooting

## **The camera fails the self-check at boot-up (Status LED keeps flashing RED).**

First, please check the position of the ON/OFF switch on the side of the camera and make sure it is in the ON position.\
\
Furthermore, check if the camera triggers 2 times during the self-check. If not, please get in touch with our support team. For debugging reasons, connecting an HDMI monitor to the cameras’ HDMI output will be helpful to check the state of the camera.

## Captured images are too dark.

In this case, the default camera settings for shutter speed and aperture need to be adjusted. Please check the [Changing Camera Settings](/rover/hardware/camera/a6k-lite-camera/changing-camera-settings.md) section of this manual.

## Captured images are blurry / out-of-focus.

The selected shutter speed might be too slow (exposure time too long) which resulted in motion blur during the mapping flight. Please increase the shutter speed (shorter exposure time).

## The camera does not capture images.

Make sure that the camera settings for trigger/maintenance string and event pin under the rover settings is correct (refer to section [Initial Camera Setup](/rover/hardware/camera/a6k-lite-camera/operating-with-spatial-explorer/initial-camera-setup.md) and [Dual A6K-Lite Setup](/rover/hardware/camera/a6k-lite-camera/operating-with-spatial-explorer/dual-a6k-lite-setup.md)). For a dual camera setup, the camera serial numbers also need to be entered correctly. \
\
If the camera status LED flashes red at the rate of the interval time, but the camera still doesn’t trigger, please verify the camera settings by connecting a HDMI monitor to it. Make sure the camera is set to manual focus.\ <br>
