I want to remotely control a Canon 7D Mark II with a 50mm lens from at least 20 meters away for wildlife photography, ideally with live view and focusing control from a laptop or tablet. This would be used outdoors without mains power, so battery-powered solutions are preferred.

I’ve considered long USB cables, USB-over-Ethernet extenders, Canon’s W-E1 Wi-Fi adapter, Wi-Fi repeaters, and optical USB cables. The W-E1 has been unreliable for me beyond about 10–15 meters, especially with trees or other obstacles.

What practical options are there for getting stable remote control with live view at 20+ meters in the field?

You can extend the Wifi range with a good antenna at one end (possibly the PC end).

Technically that would be a Wifi dongle with a removable antenna (like possibly this one where you remove the provided antenna and connect a directional one (examples only, no quality implied). And with some luck the dongle has already more range with its provided antenna than your PC.

For full remote control with live view, the most practical option from the answers is a 20m active USB 3.0 extension cable. These do exist, and if your computer can’t supply enough power, the cable can be powered from a standard 5V/1A USB battery bank.

Wi-Fi is possible, but your current experience with the W-E1 is typical: range and reliability drop quickly with distance and obstacles. One answer suggests improving range by using a Wi-Fi adapter/dongle with a better or directional antenna on the computer side, which may help, but it’s less predictable in a forest.

If live view is not absolutely required, a simpler approach is to separate monitoring from triggering: use a long-range wireless trigger for the camera and a separate remote viewing device such as a field/security camera to watch the scene.

So, in order of confidence for your use case:

  1. Active USB 3.0 extension cable + battery bank
  2. Improved Wi-Fi antenna setup
  3. Separate remote trigger + separate monitoring camera

USB-over-Ethernet was not supported by the answers as a reliable live-view solution.
