High-end cameras and displays will obviously incur high-end costs.
Back in the 1960/70s, I worked at a non-state airfield which has a 3 storey ATC facility.
When the airfield opened, the 'low-level' VCR wasn't a problem, but as the terminals expanded, the view out of the windows became more and more restricted.
The last time I visited the VCR, prior to the introduction of a new, taller structure, the VCR looked like a TV studio control-gallery, and the ATCOs were not happy bunnies.
In the early days, one of the cameras was aimed into the rising sun, to look at the 28 holding-point, and it did an 'Apollo 12'. The tels guys who installed the system were not happy bunnies.
