It's an interesting question that probably depends greatly on how the Intercept works. Having a white room isolated on its own probably does nothing. My guess is that it taps into all of the field agents on the ground, possibly through sunglasses like the pair that updated Chuck. If it sees what they see, it'd be like having Chuck's ability inside every field agent across the globe. Or it could work like Eagle Eye, tapping into every networked security camera in the country.
