City of surveillance camera every hundred steps

I notice that they installed a CCTV on top of me when I took the morning bus to work. I know that it is inevitable that they would soon install some on MRT train, my HDB flat corridor etc. That makes me wonder about few things, of privacy and Humanity; I know many Singaporean would compromise rights for security.

I also keep smiling at the camera during my journey, like an andok!
