Video Transmission Quality

Pixelated Video

There are cases where poor network quality can strongly affect video transmission, especially for Operations Hub streaming. This can result in pixelated video, frequent image freezing and/or tearing, and green splotches in the video stream. You might consider having backup option for network access where possible, such as a mobile hotspot from a different mobile provider, or even tethering to a phone.

The M210 drone also can encounter issues with pixelated video, especially when switching back and forth between DroneSense and the DJI software. When this happens, try using the pill buttons in DroneSense to switch the feed to the FPV or Map and then back to the pixelated camera. This will reset the image resolution in many cases.

Pilot Proximity

In an environment where multiple drones are flying on the same network, having pilots in close proximity to each other can lead to interference. This can especially be true with higher power controllers and with dual controller setups. Some times, you can see an immediate improvement with just a single pilot stepping away a few feet from other operators.

You also can try adjusting the image transmission settings in DJI's software to avoid network congestion with multiple pilots are present, as described in the next section.

Image Transmission Settings

There are also some cases where the video is pixelated in DroneSense but comes through clearly in DJI GO or DJI Pilot. If switching feeds to/from the FPV does not address this issue, you can switch from HD to SD streaming in the DJI app:

NOTE: The settings and available options may vary depending on the exact drone connected, installed firmware, and the version of DJI GO or Pilot you are using.

This will not adversely affect the video or image quality streamed to the pilot or on Ops Hub, nor degrade quality of media captured on the SD card.

Older Tablets

Significantly older tablets can have issues displaying video, especially after running for a period of time and/or with a poor network connection. Consider updating to a newer iPad if you are running on an older device that experiences heavily pixelated video.

 Electromagnetic Interference

Nearby electromagnetic interference also can cause the your video stream to appear degraded in the flight control app (and as a result also on Ops Hub).

If you encounter this kind of interference, one possible solution is to change the image transmission settings in DJI GO 4:

1. Open DJI GO 4.
2. Tap the … menu in the upper right.
3. Choose the HD from the left menu.
4. Tap Custom from the channel mode at the top.
5. Under Select Channel, tap to choose/change the channel.
6. Shut down DJI GO 4.
7. Restart the DroneSense flight control app and connect to the video feed on DroneSense Ops Hub.

The DroneSense flight control app will respect those settings.

You might need to experiment with the channel settings to find one that gives you the clearest picture, and the settings you choose might be different for different flights.
