Whilst reading about CCTV, I found lots of different statistics none of which I expect to be accurate. I guess there's no real way of working out if they are or not. For instance, in London there are supposedly 422,000 cameras and on average you are likely to be captured on CCTV 300 times a day. When I hear this it reminds me of George Orwell's classic book 1984, wherein we are told: 'Big Brother is watching you'. This is so true that this is now a well known TV show. People then somehow make careers from that - strange again.
The 'telescreen' system that is mentioned in 1984 is an announcement and surveillance system. It is used by the ruling party and continuously monitored by the Thought Police. The telescreens also provide party propaganda. The current CCTV's we have don't really give out information just take instead. There are many other ways propaganda is fed to us now so no need to worry there! With all this in mind BBC Culture wrote a great article on the way 1984 could actually be now.
Finally the 3 images in this post are cameras that I have designed in Adobe Illustrator. From looking at photos online I created the images and added my favourite coloured gradients.
