The Wikipedia definition of surveillance is observation from a distance by means of electronic equipment, and it may be carried out by individuals, organisations or even on a national scale. Modern technological progress has made discreet 'observation' possible to everyone through deployment of affordable and readily-available cameras and recording equipment.
It is truly remarkable just how many hidden cameras are deployed on our streets, in stores and at other commercial premises. Decades ago, this type of activity was only open to large organisations, but increasingly has become available to everyone through reduced prices of electronic components, and the increasing influence of the internet in purchasing state-of -the-art equipment. In the meantime, police and local authorities have increased their coverage ten-fold over the last few years.
Domestically, a range of devices from multi-camera digital recording stations to cameras hidden in 'coke' cans, or other household items can be purchased for less than a hundred dollars - a small price to pay for household or small-business security. Installing good security equipment can lower your insurance premiums' also having a system that is visible to prospective intruders can in itself prove to be a very effective deterrent. Added to this, there is a certain amount of peace of mind to be had from knowing that your property (and even your family) is adequately protected.
