In the world today, there are millions of surveillance cameras, or 'spy cams', watching and monitoring our daily activities. There are some benefits of course, as people who are breaking laws can be watched and caught using cameras and this helps keep our society and public places safe.

These cameras are everywhere and most are openly visible on roads, in airports, businesses, shopping centres and government buildings and even in lifts. Even schools have started using spy cams to watch student activity and behaviour.

The cameras are so commonplace now that we hardly ever even notice them. But the problem lies with the ones that are hidden away from our eyes and are unseen. Technology has helped develop tiny cameras that can be very well hidden and they can 'spy' on shoppers, workers, babysitters and people in hotels and clubs without the people even knowing.
