I may be more sensitive to surveillance than others. I work in Tech, and I was fascinated by the sheer number of sheer number of Hikvision facial recognition cameras I saw.
Here is a picture of one set of cameras around the mosque, which did not seem normal to us. My cousin pointed it out and we laughed at the blatant violation of privacy we saw - saying they don't even hide the fact they are watching https://imgur.com/a/8WbFxBi
and I'm not sure its fair to say I stayed in tourist areas, I was an hour and a half outside of town, and we ventured into poor areas of SH.
