I have an AKASO Brave 7LE. I just take out the SD card and put it in an USB reader that I plug into my home server to move the videos. Then I just use my desktop for editing with Kdenlive which has a defish filter for getting rid of the camera distortion these actioncams have.
It’s also possible to connect to the camera through WiFi, but it’s much slower than using the SD card reader.
Regarding firmware updates, I don’t think AKASO is really into that but at some point I had an issue and support sent me a file that you just put on the SD card and the camera does the rest.
