Hey, no problem. We'll just grow them on trees, or something. Or

Very true. Subways and other form of public transportation where a lot
of people sequentially pass through a tiny crossection, entrances into
buildings/highway systems, street crossings (street lights).

A mass-produced solid-state camera including optics should cost no
more than $1, or less. At current state of the art, it would be
expensive to equip each of them with image recognition (especially as
the current state of art is both puny and advances so fast), so you'd
set up distributed DSP surveillance centers.
As to limited resolution: unsharp masks. Gait, gesture and movement
pattern evaluation do not require a lot of pixels to provide good
results. Plus, zoom optics and automatic tracking. You don't have to
track the whole crowd simultaneously after you've found your suspect,
With sufficient snoopware density, you can track a suspect across wide
areas. And of course things grow very interesting if one starts to use
data warehouses to crosscorellate data gathered from multiple
sources. Very interesting indeed.
Then there will be speech recognition, chips which do on-board
neuronal OCR, body odor detectors, tags including high-resolution
positioning detectors, the whole gamut of it.

Bummer. And we were hoping ;)

LEO stuff can sure track a human moving across a landscape. And
helicopter based optics (passive infrared and optical) makes person
tracking 1) unavoidable 2) undetectable.
With nanotechnology one can make surveillance really 100%.
