I would imagine that person's life would be made very difficult. Even outside of these lettered agencies, I would imagine if someone created a system to capture the license plates of the cars used privately and publicly by government members or high ranking executives in organisations tied to the government they would create a very bad situation for themselves.
If anything has been made more than blatantly apparent in recent years it is that there are one set of rules for us and another for them.
Of course, performance won't be comparable to the commercial product here in question, but I'm certain that with some motivation you can get similar, if not better, results on better hardware.
And your second question, I would assume you would end up in jail for illegally monitoring government security employees.

(I don't really mean to endorse that article, but I do think it looks at the world through an interesting lens. WWI probably does represent some sort of transition point in history, where the idea of an actual global empire became realizable and we are still in the period of developing a global governance structure to deal with it. Maybe such a structure is not inevitable, but I think it is quite likely.)
The phrase was thought to have been "war-based" industrial complex before becoming "military" in later drafts of Eisenhower's speech, a claim passed on only by oral history. http://www.usatoday.com/news/nation/2010-12-10-eisenhower-ad...
Geoffrey Perret, in his biography of Eisenhower, claims that, in one draft of the speech, the phrase was "military–industrial–congressional complex", indicating the essential role that the United States Congress plays in the propagation of the military industry, but the word "congressional" was dropped from the final version to appease the then-currently elected officials. http://schott.blogs.nytimes.com/2011/01/25/guest-post-james-...
James Ledbetter calls this a "stubborn misconception" not supported by any evidence; likewise a claim by Douglas Brinkley that it was originally "military–industrial–scientific complex". http://www.americanheritage.com/articles/magazine/ah/2001/6/...
Additionally, Henry Giroux claims that it was originally "military–industrial–academic complex". http://www.paradigmpublishers.com/Books/BookDetail.aspx?prod...
However, Fascism is generally used because its scary and [frankly] that kind of Government/Megacorp relationship in general is scary.
Several. The fact that the economic system of the early industrial period featured an arrangement of property rights which favored holders of capital (corporations exist only as ideas, but their owners are real beings) who then exerted disproportionate power over all institutions of society, including government, leaving those capitalists the dominant power in all domains of life is why critics of that early industrial economic system named it "capitalism", and the weaving together of corporate and government power driven by corporate influence over government remains a strong feature of capitalism. (Supporters of "capitalism" who have attempted to redefine "capitalism" to mean some ideal system of perfect market freedom rather than the actual system the term was coined to refer to often treat this as something other than capitalism, or as a failed form "crony capitalism".)
More formal integration of government, industry, and organized labor is corporatism, top-down forms dictated by the central government of corporatism were features of Italian fascism and many authoritarian movements of roughly the same time. This has sometimes led to the equation of corporatism with authoritarianism/fascism, though this is an error: corporatism is substantially older, and has substantially broader reach -- it is no more equivalent to fascism than anti-communism (also a feature of fascism) is.
And, despite the rhetorical differences in how the integration works, such integration is also a feature of those Leninist/Stalinist/Maoist Communist regimes that either don't go so far as to completely eliminate private industry, or which back off from it.
Which, taken together, illustrates the reason why there isn't a term in general use for corporations (which are, after all, creatures of government) and government weaving themselves together -- its a feature of every economic system that has actually practiced in which corporations exist, from capitalism to the various reactions against liberal capitalism.

Vigilant are not setting up their own cameras to collect this.
If a group of private citizens were to pool their efforts, it would be conspiracy to break the law, just as if a group of private citizens or a corporation were to pool their efforts to displenish any other public resource like airwaves, water supply, clean water, quiet, clean air, etc.
A private citizen could not easily run them against license plate databases at scale and resolve the identity of the car's owner to the name of a real person.
A private citizen could not then take that real person's name and run it against LE databases to determine whether the registered owner of the car were a known arsonist, terrorist suspect, felon, firearms owner, or campaign contributor to whomever.
If the battle is to be fought and won, I would be surprised if "taking pictures" were the act found to be unconstitutional. I would be slightly less surprised if "storing every bit of metadata possible on every human possible" were found to be unconstitutional, and that storage / reconciliation should likely be the targets of our efforts.
