For example it is now common knowledge that IAEA shared reserved data with Israel INT agencies, and this info was used for the previous strikes.
Going back pre-Iraq-war, back when there were "inspections" and "sanctions" on Iraq, you can dig up "page 19" articles in NYTimes where -- if I recall correctly -- the US was caught putting spy equipment on the IAEA monitoring equipment in Iraq. This is (according to Iraq) what in large part triggered Iraq to kick out US inspectors. Then the Iraq (2) war started because they wouldn't let in inspectors.
Iran's theory, glossed over at the time but also reported in the rare western press articles was that the US intentionally got caught. (So that the Saddam would have explicit pressure to get the US kicked out, so that then they (US/Israel) could have a pretext to take out Iraq.) I don't know if Iran had any actual evidence to that effect or it was a bit of a conspiracy theory; I never actually read Iranian news sources whcih might have had details (or might have revealed just empty posturing.)
The traffic cameras can't tell you who is in the vehicle. Maybe they know which plate he typically rides in? But the much simpler explanation is he had a leak.
The Chinese traffic Surveillance cameras also photograph who is inside the Vehicles
2) It can be used in conjunction with other assets watching who got in etc...
> The situation on the Rhine/Danube frontier was complex. The peoples on the other side of the frontier were not strangers to Roman power; indeed they had been trading, interacting and occasionally raiding and fighting over the borders for some time. That was actually part of the Roman security problem: familiarity had begun to erode the Roman qualitative advantage which had allowed smaller professional Roman armies to consistently win fights on the frontier. The Germanic peoples on the other side had begun to adopt large political organizations (kingdoms, not tribes) and gained familiarity with Roman tactics and weapons. At the same time, population movements (particularly by the Huns) further east in Europe and on the Eurasian Steppe began creating pressure to push these ‘barbarians’ into the empire. This was not necessarily a bad thing: the Romans, after conflict and plague in the late second and third centuries, needed troops and they needed farmers and these ‘barbarians’ could supply both. But as we’ve discussed elsewhere, the Romans make a catastrophic mistake here: instead of reviving the Roman tradition of incorporation, they insisted on effectively permanent apartness for the new arrivals, even when they came – as most would – with initial Roman approval.

If Iran removes these cameras, they will have a much harder time tracking protests and dissidents.
So it's entirely possible this could be misinformation intended to mislead the regime into removing the cameras.
