i agree it would be a smart way of catching the burglar but if you place a real CCTV and a fake CCTV at 1 place but i do not agree it would save cost, won't that increase the cost instead? furthermore, since singaporeans are "kia si"
, i do not think that they would be brave enough to go and deactivate the CCTV just to rob someone for some cash. if they wanted to deactivate it, they would do it through other means other then going close to the CCTVs
