There are cameras that can see infrared and ultraviolet, what about microwaves and other wavelengths?
If we had a camera that only images microwaves for example, could we see wi-fi and Bluetooth as they reflect off surfaces?
What are the main limitations of building something like this? Is it the size difference between wavelength and sensor size?

Yes and no…
it’s not a camera as such, but still an RF visualizer
