The economy may be a little flimsy at the moment,but this project shoudn't be too costly, dependent on the level of technology and maintainence.
Though there are so many beneficials with the CCT surveillance,there is always the bad side of it too. Besides cost,there will always be people who feel exposed to the camera's and that their privacy is destroyed. Although they may be true,as long as they follow the rules and stick to the law, they should not be worried or bothered at all.
All in all, though I concede that CCT surveillance might have its drawbacks, the security benefits it brings vastly outweigh the costs incurred. Therefore, I will respect all efforts made by the government to utitlize this tool to improve Singapores' safety.
