In the field of security systems, the use of CCTV camera system is being highly publicised not because it is the most popular type of security system but because it is the security system that is being constantly attacked by critics. One of such critics is the Big Brother Watch an organisation that emanated from the Taxpayer’s Alliance and have been regarded as one of the main critic with regards to CCTV camera use especially in public places. The Big Brother Watch questions whether or not CCTV camera systems are actually helping in the governments’ effort in crime prevention and even in solving different crimes, this question emanated from the fact that there are sometimes inaccuracies in the data being gathered by the CCTV camera systems. Such negative description by the Big Brother Watch was denied by Pauline Norstrom, the BSIA CCTV section chairman, she stated that the negative assumptions or criticisms being thrown at the CCTV camera systems’ accuracy or effectiveness is without any basis because the reality is, in the United Kingdom police authorities have been using the data gathered by CCTV camera systems in event reconstruction which would help investigators in identifying the identity of the offenders or even identify events that led to the commission of the crime.

Another criticism being assailed by the Big Brother watch is the utilisation of public funding in order to set-up or install the CCTV camera systems in public places, further they have stated that the answer to the growing problem in criminality is by deploying more police officers in the streets. In this contention BSIA replied that the effective use of CCTV camera would reduce the need for any additional police officers but still giving the same if not beyond, effect as when more police officers are deployed, for the same price or much lower price since there is no need to pay the salary of officers. Indeed the use of CCTV camera system is a very powerful weapon that helps police officers in their fight against crime for a lesser cost
