> China currently has an estimated 200 million CCTV cameras watching over its citizens

I wish reporters would stop mixing up cctv cameras with facial recognition cameras. 200 million cctv cameras is a meaningless number in the context of facial recognition. How many of those cameras are capable of facial recognition? No wait, that’s way to “sciencey” and detailed for this clickbait article.

Facial recognition is a software function which can be performed on image data coming from any camera with sufficient resolution, most likely that includes the majority of surveillance cameras deployed in China. China might suffer under an antiquated and corrupt political system but the country does not lack modern technology.

This looks to be either 36 or 40, can't quite count the discrete units correctly from the photo.

Let's say it's 40 x ~14MP cameras fixed in to a housing.

What's stopping anyone from using higher resolution subunits and more of them.

Or, if you bolt ten of these things together do you get a 5000MP camera?

China might suffer under an antiquated and corrupt political system but the country does not lack modern technology.

Furthermore, facial recognition is constantly improving, and a camera that might've been inadequate for it a few years ago can now be used for matching, if not training.

Combine that with the replacement rate of cameras, and you get two factors crossing each other and meaning that the vast majority of those 200M cameras can already be used for recognition, and the ones that can't today, will be soon.

I guess the headline here isn't that these plucky scientists managed to stick a bunch of cameras together, but rather the Chinese state can stick one of these in a crowded area and instantly identify everybody within it.

China has a very large number of cameras on their roads that essentially constantly surveil all of the drivers on the main roads. I imagine that a sizable chunk of those quoted CCTV cameras are those.

Yeah, I guess achieving arbitrarily huge images is just a matter of increasing the resolution/number of sensors and then applying the correct optics. The bottleneck (and technical achievement) of a system like this would be the processing power required for stitching and analyzing these massive images in anything close to real time.

other things will probably limit visibility, like earth curvature, buildings, etc... probably better to have multiple of those arrays? I would be really curious to get details on the lens setups for this array though.
