Good point about the need for a new control tower, however if it ever happens the current VCR would be retained as a stand-by.
Unlike ATC Ground, Apron (Airfield) Control need to see each and every stand to ensure safe allocation. Nowhere on the airport can achieve this so even if they were relocated into the current VCR, they would still need CCTV for all of T2, T3 50s, B Pier evens and stands 22/31/32.
Sorry about your CO2; CCTV is a bi-product of operating a safe airport.
