Web Pages Overview

When connecting to the Double4k camera, the home page is brought up.  In addition to this page, there are a number of other pages available from the menu on the left side of the screen.  If the menu options are not visible on your screen, click the 3 lines in the upper left side of the web page to expand the menu names.


Allows an overview of the current camera configuration, SD card capacity, and session status. Controls are provided for manually starting and stopping sessions as well as triggering images.  It is split up into a number of different sections.

Session Status

Status:  Indicates the state of the camera session.  The typical values are: 

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

Folder:  When a session is active, this displays the name of the session.  Clicking on the session name will bring you to the contents of the session folder.


ID     : The internal ID of the imager

Name   : The name of the folder that this imagers' images are stored in

Recent : A link to the most recent image taken by this camera

T      : The number of images taken this session

P      : The number of pending images (requested, but no captures) this session

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).  In RTK systems, the age of the last RTK corrections message in seconds is also displayed.

  • 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.

SDCard Storage:  The amount of space remaining on the installed SDCard

Session Control

If a session is not running, this allows you to name and start a new session on the camera.  To do so, type the name of the session in the text box, then click the 'Start Session' button.  The status at the top of the screen should change to indicate the 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, clicking the 'Trigger' button will cause an image to be taken.

Note: In order to trigger an image, a session must be actively running.

Switch Config File


Allows the camera configuration to be changed to a number of different pre-saved files located either on the SDcard or the internal memory.

To use this page, first select a configuration file that you would like to change to from the drop-down. Configurations with [Internal] are stored on the camera itself, while those with [SDCard] are stored on the card and can be modified by the user.

After selecting a file, the details will appear in the Selected Details section below. After confirming that the file is correct, click the 'Apply' button to load the configuration onto the card.

To confirm that the changes have been made, wait 5 seconds, then examine the 'Current Config Settings' and 'Config Details' section to make sure they have been updated.

Browse SDCard


Allows browsing and downloading of the contents of the SDcard.

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:


Latest Image Camera 1/2


View the most recent image captured by the indicated 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


Allows the user to update the firmware from the web interface.

To use this page, see the Updating the Firmware section below.

Manually Triggering the Camera

In some cases, it may be useful to manually trigger the camera via the web interface.  This can allow for testing images either on the ground or in a lab environment where a lack of GPS may prevent the camera from starting a recording session.  To do this:

  1. Connect to the Double4k diagnostics page using the procedure at the top of this document
  2. Navigate to the 'Home' Page
  3. Check if a session is active by looking at the top of the Homepage 
    • If a session is active, the status should be STARTED
    • If no session is active, then start a session by going to the 'Session Control' section, entering a session name, and clicking 'Start Session'
  4. Find the 'Trigger Control' session and click 'Trigger'
    • An image will be taken each time the trigger button is pressed
    • Multiple triggers can be queued up by clicking the button multiple times in a row
    • If the trigger button is greyed out, make sure a session is running
  5. Check the Session Status section to verify an image has been taken
    • If an image is taken, the Recent link will update to indicate the new most recent image
    • The Taken (T) count will also increment for both imagers

Updating the Firmware

  1. Connect to the Double4k 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 the ‘Upload Button’
    • The screen will change to an upload in progress window
    • Monitor the bottom of your web browser to see the upload progress (see image below)
  5. Wait for the update to finish uploading to the camera.
    • If the update completes successfully, a ‘Firmware File Successfully Uploaded’ message will appear
  6. The camera will now reboot a few times while it applies the hardware configuration and update file.  During this time, the light will rapidly blink red and the camera may restart
  7. When the update is complete, the bottom LED will remain solid green.
    • Ensure the bottom LED on the camera is solid green for ~20 seconds
    • If it is blinking red, the update is still being applied, wait for it to finish
  8. 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

Once the camera has finished applying the update, verify that the update has been applied by the following procedure.

  1. Connect to the Double4k 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
