Transmit video from drone to laptop via WiFi

Drones and Model Aircraft Asked by user1876484 on August 15, 2020

I recently decided to build my first drone and bought Eachine Tyro 129 KIT. It has a 5.8GHz video transmitter – xf5804 which is supposed to send video to 5.8GHz goggles. I don’t have goggles and I’m not sure I want to buy it. My laptop (Debian10 Linux) has WiFi that can operate on 5.8GHz frequency.

  1. How can I transmit video from the drone to the laptop directly? Which extra software and/or hardware do I need?
  2. What maximal distance can I get with the video transmitter operating in the 600mW mode?

This is not possible, at least directly. Although the two technologies use the same frequency range, they are very different communication protocols.

A possible solution would be to buy a compatible video receiver (which might be the goggles) which has a video output - typically composite, for analogue systems - and a USB video capture card for your laptop.

Regarding signal range, the product page you linked to indicates ≥2km at 600mW.

You have a few options. One is to switch to a digital video system such as the fat shark bytefrost and do something like this to convert the video to a format compatible with your laptop: https://altrubots.com/register-to-rc-anywhere.php

Essentially the above link documents how to convert a digital fpv feed into your laptop for doing low latency video calling, but you dont have to do the video calling part. You can skip the portions about the transmitter unless you want to control the whole drone from your PC.

Or, you can do something hacky that I have done before... which is buy the display and then pop it into a cheap pair of fpv googles. Then put a usb webcam into the goggles where you would normally put your eyes. Then boom! You can see what the drone sees via a usb camera.

You can also utilize a analog to digital converter as other users have replied, but you are going to have at least 1-2 seconds of latency unless you get a converter in the 1000's of dollar range.
