RedEdge-M Manual: Camera Configuration and Live View

RedEdge-M Manual> Camera Configuration and Live View

The RedEdge-M camera hosts a WiFi access point that is used in conjunction with any WiFi-capable device for configuration of the camera and live preview of images acquired with the camera.

Establishing WiFi Connection

Any device (computer, tablet, or smartphone) can be used to establish a connection with the camera. To establish the WiFi connection:

  1. Turn on the camera and wait for initialization process to complete
  2. Use the device’s WiFi configuration method to search for a WiFi access point called “rededgeRMXX-XXXXXXX-XX”, where the Xs are the serial number of the camera. The serial number of the camera is printed on the rear of the camera.
  3. The password for this WiFi access point is “micasense”.

Once connected to the camera’s WiFi, open any web browser and access the camera’s web page by typing in “” in the address bar of the browser.

There are 4 main “pages” for the camera:

Home Page

Provides status information for the camera and the GPS receiver that is connected to it.


DLS Verification

You can verify that the DLS is connected to the camera from the camera configuration home page. If connected, the DLS status should be green and display “Connected”.


In the Camera Settings page, under “Advanced Configuration” in the “Multi-Camera Configuration” section, the DLS serial number and software version should be displayed.


Live View Page

Provides a live preview of images captured with the camera.



Imager Nomenclature


Whenever the camera captures images manually (using either the physical button or the web button), the selected image(s) will be displayed in the Live View page based on the setting of the “Band” pull-down menu.

Capture: The Capture button forces a capture for the camera, and is equivalent to pressing the Manual Trigger button on the camera.

Streaming: The Streaming checkbox is used for near-real-time preview images from the camera. When the Streaming mode is enabled, the images shown will update as quickly as the camera can support it (approximately twice a second). Note that Streaming mode does not save any images to the SD card. It just enables fast capture of the camera for preview purposes only.

Streaming mode is intended for live-preview. It is recommended that streaming mode be disabled before any other operations (particularly before enabling Auto-Capture mode or flying).

Coverage Page

The coverage page provides information on the geographic location where images in the SD card were captured based on the GPS module information. This page also provides a calculator for estimating parameters for mission planning.




Clicking the “captures.kmz” link will cause the camera to generate a KMZ file that will be downloaded by your browser. The KMZ file contains the lat/lon/alt of all captures in the SD card and can be used to verify coverage after a flight or series of flights. The KMZ file can be opened using Google Earth or a GIS application.

Pre-Flight Estimator

The Pre-flight Estimator is a calculator to estimate the results of a flight mission. Enter the mission parameters and press the “calculate” button to see the results below.

Coverage Estimator

The Coverage Estimator is a tool for quickly checking that a flight has sufficient overlap. From the initial Coverage Page, select one or more image sets to estimate and click “Next” (note: image sets must be geographically close together in order to work properly).

The Flight Adjustment tab should appear, and show a summary of its current estimation settings. Camera Orientation indicates the directionality of the camera with respect to the aircraft, as shown below.

The Flight AGL is estimated based on the GPS positions recorded for the images, with the assumption that calibration panel pictures were taken near ground level, but if the estimate is incorrect, you can manually enter the correct AGL.

The Estimate Resolution sets the quality of the output map. Low is sufficient for most applications.

Clicking “Draw Coverage” will render the coverage estimate. The rendering time depends on your device’s CPU, the size of the field, number of images, flight AGL, and quality setting, but typically runs in under 30 seconds on a modern smartphone.

Finally, you will be presented with an estimate of your coverage. Any area that is dark green has a high probability of correctly being processed in Pix4D or another image processing platform. Areas that are yellow may work, but likely will not. Red areas will almost certainly not process correctly. Edges around the field will typically show as red or yellow. This is okay as long as the data you are trying to collect is all contained within the dark green region.

class="wysiwyg-font-size-small">Example of Poor Field Coverage

If you discover your field coverage estimate is similar to the poor field coverage map shown above, double check to make sure the Flight AGL is set correctly. If the Flight AGL is incorrect, click back on the Flight Adjustment section, correct the Flight AGL, then click on “Draw Coverage” again. If the Flight AGL is correct, your overlap settings may have be wrong. You will need to capture more images of the field to ensure that post-processing will be successful.

See Best Practices for Data Collection for more details on recommended data collection methods.

Settings Page

The settings page is used primarily to configure the Auto-Capture options for the camera. The camera supports three methods of Auto-Capture: Timer mode, External Trigger mode, and Overlap mode.  


Timer Mode

 Use the drop-down menu to select Auto-Capture Mode as “Timer”


  1. In the updated window, specify the interval between pictures to the desired setting. If the timer interval is set to less than 1.0 seconds, the camera may not run at the specified interval, but will capture as quickly as it can (about once a second).
  2. Press the “Save” button to save the Timer mode settings.
  3. Press the Start button to begin capturing images at the desired interval rate.
  4. Press the Stop button to stop capturing images

External Trigger Mode

  1. For external trigger mode, you will need to connect a triggering signal to the camera – refer to the RedEdge->M Integration Guide.
  2. Use the drop-down menu to select Auto-Capture Mode as “Ext. Trigger”


  1. In the updated window, select the external trigger mode from the list. The settings are as follows:




Rising Edge

Camera will trigger on the rising edge of a pulse

Falling Edge

Camera will trigger on the falling edge of a pulse

Short PWM

Camera will trigger if PWM transitions from longer than Threshold to shorter than Threshold

Long PWM

Camera will trigger if PWM transitions from shorter than Threshold to longer than Threshold


  1. For PWM mode, enter the threshold PWM – note that this value is in ms (milli-seconds), so the value is typically between 1.0 and 2.0.
  2. Press the “Save” button to save the External Trigger mode settings.
  3. Verify that the triggering is functioning by commanding a camera capture through the host device.

Overlap Mode

  1. Use the drop-down menu to select Auto-Capture Mode as “Overlap”


  1. In the updated window, select the Target Alt to be the altitude AGL (Above Ground Level) at which the aircraft will be operating during the mapping mission. Note that this is specified as >AGL altitude.
  2. Specify the Along-Track Overlap as a percentage (%) of image that is common between one image and the next one.
  3. Press the “Save” button to confirm the settings.
  4. When the aircraft reaches the target altitude minus 50 meters, it will initiate taking captures and will take a capture if the distance traveled is detected to be greater than the required distance at the specified target altitude as specified in the % overlap setting.
  5. When the measured altitude is lower than target altitude minus 50 meters, the camera stops taking captures.

Advanced Configuration

The Advanced Configuration menu provides controls for managing file storage for RedEdge-M, as well as Ethernet and Multi-Camera configurations.Make sure to click the “Save” button after making any changes, or the changes will be lost.


 You can specify the RAW Format to be either 12-bit DNG or 16-bit TIFF. The 12-bit DNG format will produce files that are 25% smaller in size than 16-bit TIFF files, but are not supported by some image software.

You can specify how you wish to use the PPS pin on the camera. See the RedEdge-M Integration Guide for details.

The menu also enables the user to specify which bands to capture to SD card. The default of capturing all 5 bands is the recommended setting. However, if only a subset of the bands are desired, the other bands can be de-selected. Click “Save” button to commit any changes. 

The Network Mode is only relevant if you have more than one RedEdge-M camera. The table below the setting indicates the settings of all other networked cameras. In addition to configuring a single master, all of the camera software versions should match. After changing the camera’s network mode, you must click “Save”, and then reboot the camera in order of the new setting to take effect.

Ethernet Configuration allows you to assign a different IP address to the camera. Note that this will NOT configure the WiFi address, which will always be 

Manual Exposure

Manual exposure checkbox enables manual control of the exposure and gain of the camera, with settings available in the Live View Page. This is an advanced operation option and should normally NOT be enabled.
