This reads more like an advert for the company pushing this tech than an actual article.
Yes, some smaller airports don't always have an ATC, but those are for smaller aircraft, who have procedures for flying in such airports, or more likely, fields!
Relying on remote cameras as a means of providing sufficient information to a remote controller is ludicrous. Don;t expect this crap to be mainstream anytime soon. More likely cockpit technology will ease the burden on ATC than bloody cameras on remote towers.
I can think of several safety-critical issues with this, and that's just from an ICT point of view, let-alone other ATC-specific issues.
I call BS on this one......
