Over the past twelve
years, digital
cameras have shrunk
in cost and size,
and have
proliferated across
the country.
Networking these
cameras used to be a
significant expense,
but now thanks to
the Internet,
wireless hubs, and
progress in digital
streaming and image
compression,
transmission adds
little expense or
technical
challenges.
As a result, and
partly in response
to a growing
perception that
video surveillance
increases our
security, video
surveillance of
public spaces is
increasing rapidly,
by public sector
authorities, private
sector parties, and
property owners.
