How to transfer the video signal from the camera over the network to a computer?

Question

CCTV

Hello! I'm interested in the question of how to transfer a picture from a camera (sj4000 or gopro) with a minimum delay (or better without it at all), preferably using a wireless connection at a distance of no more than 100 meters. The final goal is to broadcast from the camera in real time to the screen.
Solutions that I have already come across, but unfortunately they do not fit:
WHDI transmitter - distance no more than 50 m. More than 50 m - exorbitant prices.
USB extender - plug usb from the camera into the extender and then the extender into the wifi router. In this method, I am absolutely not sure and the price comes out quite a lot.
Standard wifi in the camera - insanely huge delay.
UPD.
1) I came across an E-flite C-GO1 camera with a built-in 5ghz transmitter, but there is no adequate view of the picture that the camera transmits in real time
2) You can also use the phone as a camera, but then the question is which one now supports a good picture and quite productive?

Answer 1

If the goal is cheap and in real time, then no way.
What's the budget? What is the reason for choosing such cameras?
