There is cameras with the traffic lights and many other locations as well.
You cannot enter the main street area of the town from any direction without passing under one. That area is commerce and industry as well.

When you go into businesses they are rigged with cameras as well. When you are going through the area before entering directly into the commerce section, the out skirts of town, gas stations, police hidden locations and critter cams will get you and home security cameras as well.
They are way more places than we think they are.

It has been that way for some time now, works out pretty good as well for catching what needs caught.
