On the one hand, some results of studies could be considered to evaluate as an advantage the use of CCTV. According to Burton & Whitbread (2015) and Bathurst (2015) the criminal rate can be reduced on average approximately 35%, allowing also to have positives results in order to catch thieves (Armitage, 2014 & Bathurst, 2015).

In contrast, these arguments could not be reliable in the long term, because the percentages of criminal activities had decreased in almost a third.

On the other hand, some opponents claim that it cost too much to use CCTV, and government need to spend for the following maintaining or running (Burton & Whitbread, 2015). Armitage (2014) supports this point , he finds that it may cost 12000 for each camera. In other hand, Burton and Whitbread (2015) also state that CCTV seems to be not effective enough in controlling the crimes. Shanks’s (2016) study suggests the same view. He have found that even street lighting can increase the efficiency in reducing crime which obvious more cheaper than a camera. Besides, he shows that after a period of time, it could become  less use compared with the first time An example a town supports that it is not useful.
