Diagnostics Web Pages Overview

Connecting to the Double 4K camera will pull up the homepage. You can access additional pages from the left-hand menu. If you don’t see this list of pages, click the three lines in the upper left corner of the web page to expand the menu.


On the homepage, you’ll find an overview of your current camera configuration, SD card capacity, and session status. You’ll also find controls to manually start and stop sessions and trigger images. 
Session Status

Status:  Indicates the state of the camera session. Typical values are: 

  • IDLE: The camera is waiting for a session to start. No images will be taken.
  • STARTING: The camera is initializing.
  • STARTED: The camera is ready to take images.
  • STOPPING: The camera session is shutting down.

Folder: Displays the name of the active session. Click on the session name to view the contents of the session folder.


  1. ID: The internal ID of the imager.
  2. Name: The name of the folder where the imagers' images are stored.
  3. Recent: A link to the most recent image taken by this camera.
  4. T: The number of images taken this session.
  5. P: The number of pending images (requested, but no captures) this session.
  6. I: The number of ignored trigger requests.

Current Position

Latitude/Longitude/Alt: The current latitude, longitude, and altitude taken from the autopilot or connected GPS unit.

Sats: The number of satellites used to compute the current position.

Quality: The relative quality of the GPS Fix.

  • NO_FIX: Not enough satellites are visible to obtain a position fix.
  • ACQUIRING_FIX: Some satellites are found, but not enough to get a position.
  • LOW_ACCURACY_FIX: Position is found, but the accuracy is very low (typically > 5 meters)
  • ACCURATE_FIX: Position is determined (<5m accuracy). In some modes, this triggers a session start.
  • HIGH_ACCURACY_FIX: Highly accuracy fix (typically on RTK systems and <1m).

Diff: The status of the differential GPS corrections (typically used in RTK systems). RTK systems display in seconds the age of the last RTK correction.

  • NONE: Differential corrections are not used.
  • DGPS_FIX: Satellite-based corrections are being used.
  • RTK_FLOAT_FIX: RTK Float solution is being used. 
  • RTK_INTEGER_FIX: RTK Integer solution is being used (highest available accuracy).

Roll/Pitch/Yaw: The current attitude of the camera in North-East-Down coordinates.

SD Card Storage: The amount of space remaining on the installed SD card.

Session Control

If a session is not running, you can name and start a new session using Session Control. Type the name of the session in the text box, and then click the Start Session button. The status at the top of the screen will reflect the new session name and status after a few seconds.

To stop an active session from taking pictures, use the Stop Session button.

Trigger Control

When a session is active, you can click the Trigger button to take an image. Note: In order to trigger an image, a session must be actively running.

Switch Config File


Under Switch Config File, you can change the camera configuration to pre-saved files located on either the SD card or the internal memory.

  To change the camera configuration:
1.  Select the configuration file you would like to use from the drop-down menu.
  1. [Internal] means configurations are stored on the camera.
  2. [SDCard] means they are stored on the  SD card and can be modified.
2.  After you select a file, the details will appear in the Selected Details section.
3.  Confirm that the file is correct, and then click the Apply button to load the configuration onto the SD card.
4. To confirm that the changes have been made, wait 5 seconds, and then examine the Current Config Settings and Config Details section to make sure they have been updated.

Browse SDCard


Under Browse SDCard, you can browse and download contents of the SD card.

To skip to a particular folder on the SD card without clicking through each directory, enter the path you wish to browse to in the path argument of the URL. For example, to skip to the web_session folder of the SD card, use the following: /sdcard?path=/snapshots/web_session

Latest Image Camera 1/2


Under Latest Image Camera 1/2, you can view the most recent image captured by the camera. The page will automatically refresh every 5 seconds and continue to display the most recently captured image.

Note: This page is only available when a session is active.

Update Firmware


Under Update Firmware, you can update firmware from the web interface. See the Updating the Firmware section below for instructions.

Manually Triggering the Camera

In some cases, you may want to manually trigger the camera via the web interface. This allows you to test images on the ground or in a lab environment where lack of GPS may prevent the camera from starting a recording session.  

To manually trigger the camera:

1.  Connect to the Double 4K diagnostics page using the procedure at the top of this document.
2.  Navigate to Home.
3.  Check to make sure a session is active by looking at the top of the homepage.
  1. If a session is active, the status should be STARTED.

  1. If no session is active, start a session. Go to the Session Control section, enter a session name, and click Start Session. 

4. Find the Trigger Control session and click Trigger.
  1. The camera will take an image each time you press the Trigger button.
  2. You can queue up multiple triggers by clicking the button multiple times in a row.
  3. If the trigger button is grayed out, make sure a session is running. 

5.  Check the Session Status section to verify the camera has taken an image. 
  1. The Recent link will update to show the most recent image.
  2. The Taken (T) count will also increment for both imagers. 

Updating the Firmware

1.  Connect to the Double 4K diagnostics page using the procedure at the top of this document.
2.  Click on the Update Firmware button on the main web page.

3.  Click the Choose File Button and select the Snapcam-ota-*.zip packet provided in the updater.

4.  Click Upload.
  1. The screen will change to an upload in progress window.
  2. Monitor the bottom of your web browser to see the upload progress (see image below).

5.  Wait for the update to finish uploading.
6.  When the update completes successfully, you will see a Firmware File Successfully Uploaded message.
7.  The camera will reboot a few times while it applies the hardware configuration and update file.  
  1. During this time, the light will rapidly blink red and the camera may restart.
8.  When the update is complete, the bottom LED will remain solid green.
  1. Ensure the bottom LED on the camera is solid green for ~20 seconds.
  2. If it is blinking red, the update is still being applied. Wait for it to finish.
To verify the update has installed, follow the Checking Firmware Versions procedure below.

IMPORTANT: If you are connected via a wireless network, you will have to reconnect the camera after it reboots and before verifying the update below.

Checking Firmware Versions

To verify that the camera has applied the firmware update:
1.  Connect to the Double 4K diagnostics page using the procedure at the top of this document.
2.  Click on the Browse SDCard menu option.

3.  Using the web based file browser, navigate to /info/

4.  Verify that the version in the Release Info section matches the version that was applied.
