"...On Monday the chief of anti-terrorist department of Scotland Yard, Peter Clarke, informed that the CCTV recordings from central London showed that all the suicide bombers arrived at the King's Cross station on Thursday, at 8.30, about 20 minutes before the explosions in three underground trains..."
London is probably the best protected city in the world. It draws from history that had forced the British government to fight IRA terrorism a few dozens of years earlier before similar phenomena emerged in other countries. The density of cameras in the city is hard to imagine for someone coming from other European capitals, not to mention other cities. The best guarded places include train and bus stations, underground, governmental buildings and national monuments. It is common to install cameras in clearly visible places, both to scare off potential offenders and protect the cameras against attempts of destroying. Of course, there are also lots of hidden (spy) cameras, working, among others, as protecting devices for the main equipment. Everyone can see numerous posters, boards or plates informing about surveillance and possible consequences arising form the use of evidence such as recorded video. The priority of surveillance over aesthetics of facades seems to be obvious.
We hope that the pictures showing fragments of installations may be useful for CCTV designers and installers, as well as the contracting parties. They allow to see installation methods, locations of cameras, the devices used - just watch how they do it!.
Information about surveillance. One of the very important parts of CCTV surveillance system, about which the contracting parties often forget, is information that the area is monitored. The information may deter potential offenders from criminal activity.
It has to be emphasized that this kind of information does not help to protect the monitoring system against destroying the devices or cabling. The basic rule is that each camera should be monitored by another camera and the cabling has to be concealed or heavily protected. In case of low budget (too few cameras), it is important to locate the cameras in hardly accessible places and protect them mechanically.
