In my case the city had to publish their agreement with Flock and I was able to find the city council presentation showing exactly where they put the cameras, and many selling points of how great Flock is. In fact, someone else in my town had already marked them.

Obviously, this website does nothing for us, just glance up at any egress or ingress to where you live (in the US) and note you've been tracked. Or feel free to update the node with better information if you have it.

Some cities just publish these locations, and in many (most?) jurisdictions you can just FOIA the camera placements.

This is because the metadata in OSM doesn't include the tags that Deflock looks for:

You can see the requirements here https://deflock.me/report/id but the two you're looking for are.

I think they should add Siemens Sicore cameras to their known camera database, but they do show up on Deflock despite not being mentioned explicitly on the website. Here is an example in one of my contributions via OSM. https://deflock.me/map#map=18/53.786783/-1.551438

One thing you could do is go and physically look at the camera. https://deflock.me/identify has pictures of cameras from at least the major providers.

There are probably a lot more cameras than are listed in the database.

You could point a camera down the street you live on and record the license plate of every car that passes and video of every pedestrian for a few hundred dollars.

I thought about doing this a couple of years ago when there were a few instances of theft going on. To get into or out of my neighborhood, you have to drive by my home and I wondered if I could capture the license plate of the thieves.

Yup, about 100k installed vs about 40k mapped
