Troubleshooting Triggering Issues

Prior to operating the camera there are critical steps that need to be followed. They are outlined in the MicaSense Sensor checklist for operation.

Once you have connected to your MicaSense sensor, setting your camera up to trigger is a simple process. However, there are many factors that may lead to your camera not triggering during flight. This article will offer possible causes and troubleshooting tips that may help determine and solve the issue. 

Triggering issues can be broken down into three scenarios: No images were captured on the SD card, the camera stopped capturing mid-flight, and inconsistent triggering leading to data gaps. We separate these scenarios below and outline possible causes and ways to avoid and/or troubleshoot them. 

1. No Images Captured

  • Check cable connections, are they secure?
  • Was the triggering method set up via the WiFi interface before flying?
    • Were you using overlap mode? (If using Atlas flight, the camera is automatically set in Overlap Mode) 
      • Double check your target altitude, the camera starts capturing 50 m below target altitude and stops capturing if the altitude goes 50 m below the target altitude.
      • Did the camera have adequate GPS reception prior to the flight (shown on the WiFi interface)? 
        • Overlap mode requires adequate GPS reception to begin capturing.
    • If flying in timer mode, test your power supply and make sure it provides the necessary voltage, even under load.
    • External trigger
      • Is the trigger cable connected to triggering source?

2. Camera Stopped Capturing Mid-Flight

  • Could be a power issue
    • Test your power supply under load: Without an SD card installed, does the camera operate properly set to 1 second timer mode? It should run in this mode indefinitely at room temperature, and the user should see a blue blink approximately once per second as the camera captures. This will help to verify that the power supply is sufficient. If connected to the WiFi capture page, the image should update each time the camera takes a picture (there is no need to press the capture button on the web interface).
    • Test an alternative power source
  • Ensure you have ample storage available prior to flying

3. Inconsistent Capturing (gaps in data)

Post-Flight Check

To ensure that you captured the expected amount of captures during your flight, check the coverage estimator after your flight. This can help you to determine whether your flight was successful or not prior to heading out of the field.


If you are still experiencing triggering issues, please send a description of the issues, as well as log files (paramlog.dat and diag.dat) from an affected flight to
