Where the cameras are
Every device here is one somebody documented in a public dataset: plate readers, cameras, gunshot detectors. It is not complete, and that it is the largest public accounting in existence is the problem it was built to show.
Other countries have cameras. America has vehicle tracking. Of 115,324 plate readers documented worldwide, 110,789 are American and 4,535 are everywhere else combined.

By manufacturer
One company accounts for most named devices in the public record. Nobody voted for that.
Plate readers by country
Every country with documented plate readers, ranked. The scale is logarithmic - a linear axis would render every country except one as a flat line.
When devices entered the public record
Read this carefully. These dates record when a device was first documented by a member of the public, not when it was installed. A spike means people started looking, not that cameras appeared. The gap between the two is the accountability problem in one chart.
