That just looks like a "standard" camera box. Probably some kind of little NVR in it, along with a wireless network node of some sort (mesh, 4G, etc.).
There isn't any single company that supplies those, but there are a handful of security dealers that essentially assemble them.
That one looks like it might be old, the PTZ on the bottom looks like a really old Pelco unit.
I was told that many of the boxes in Chicago just have fake cameras and a blue flashing light to let you know you're being "watched". Not sure if it is true or not but you can buy fake security cameras.
You can certainly buy fake cameras. You can also buy real cameras for under $40 and just not hook them up.
Many cities are starting to deploy these municipal surveillance boxes, many with grant funding. So, it's hard to say which are real and which are not anymore.
