CCTV is important for crime prevention. I think that a mix of real and fake CCTVs will help to lower costs. We could probably put the 'fake' CCTVs concealed in dark alleys where there are little people but enough for the would-be-criminal to see it. A criminal would be nervous and suspicious, so when the moment he or she sees the fake CCTV, he would be scared and be more likely to leave traces for the police to track down. The 'real' CCTVs should be place at crowded places as these places are often harder to see crime
