Ever wonder how the voices from V2K say they can see you? Well it’s all radio for the most part, so any device that works with radio will work with it. Certain Back Scatter X-ray devices like those used in airports use radio waves. They can see through things and see you at all time, they can also work from long distances if it’s someone with a radio using the Lens Effect. It would be from a top-down view if they were doing that.
They can see you much like the below pictures from a change.org petition.
