Remote Troubleshooting

  • Format the SD or microSD card to remove corruption that may be causing errors. You can format the card from your installation’s Config page under Advanced options
  • Mach II: ‘Delete all photos from the camera SD card…’, then click ‘Save’.
  • Pro or Mini: Leave the camera ON for longer at each interval. You can change these settings on your installation’s Config Page under ‘When to take photos’ section. We recommend setting the interval between 45 – 90 seconds.
  • This will clear all photos from the SD or microSD card. Photos that haven’t been uploaded, or copied to the external drive, will be lost. With an End of Day upload schedule, you can attempt to upload the missed photos, otherwise a photo backup will require a site visit.

To set an End of Day upload, go to your installation’s Config page and find the ‘End of day uploading’ section. Tick the checkbox and choose a time to upload. The schedule must not coincide with your regular photo taking intervals. You can select a date range to look for specific photos to upload.

  • Advanced feature for experienced users: If you are using a Mach II, you can use Remote Camera Control to reset some basic settings on the camera. You can change these settings from your installation’s Config page under ‘Camera Control’.
    • Try changing the F-number / aperture, and/or ISO
    • Recommended settings: Aperture priority exposure mode, F8 – F10, ISO100 – 400, white balance fixed, manual focus.

  • Updating to the latest firmware can improve system behaviour. Contact our Support Team to update the firmware remotely.

On-site Troubleshooting

  • Confirm that the camera is ON and there is a microSD card in the system
  • Reconnect or replace the camera cable/s:
    • Mach II: Replace the USB cable.
    • Pro: Replace the SD ribbon, trigger and/or power cables.
  • Format the microSD card from the camera menu or replace it. To access camera settings:
    • Mach II and Pro: Switch the controller to SETUP/Camera test mode.
    • Mini: Switch the controller to Camera test mode, and the camera to ON.
  • A microSD card for Pro or Mini should be Class 4 or lower, and NON UHS-I spec.
  • Keep the camera for a few hours on camera test/setup mode, with a fully charged battery or on AC. This will charge the internal camera battery-capacitor.
  • Use the recommended camera settings:
    • Aperture priority exposure mode, F8 – F10, ISO100 – 400, white balance fixed, manual focus. Set time zone, time and date. Then turn off camera and turn it back ON. On the Mini you can leave the camera OFF. (more on camera settings)
  • Reset or replace the camera. If there is an error message on the camera display, use this to diagnose what needs to be reconnected or replaced.
