Michael McCahill and Clive Norris provided a 2003 estimate of 4.2
million CCTV cameras in the UK.
Garry Armstrong and Clive Norris provided a scenario in 1999 in which
a fictional character on a fictional journey around London would be
captured on 'security cameras' 300 times in the day.
Graeme Gerrard provides alternative estimates in March 2011 of:
- 1.85 million CCTV cameras in the UK
- an average person doing average things will be 'caught' on CCTV
less than 70 times per day, mostly in the workplace or in shops
The difference seems to me to be essentially irrelevant.
Very large numbers of these installations resulted from knee-jerk
reactions to current security concerns, were not subject to careful
evaluation, lack the associated infrastructure and resources, and
demonstrably don't make significant contributions to security.
Yet, whether or not they make much in the way of positive
contributions, they bring with them privacy threats that are both
specific (leakage of personal data, inconvenience and worse arising
from false positives) and generic (chilling effect); and in many
cases those privacy threats are subject to seriously inadequate
safeguards.
Do we have a citizen / consumer / employee Standard in place that can
be used to assess existing installations and proposals for new and
changed installations, and to guide organisations undertaking their
own assessments?
Here's one proposal for such a Standard:
