Heya, thanks for adding to OSM. When you add these cameras, please make sure you aren't attaching them to anything else. In this case, for example, you attached the camera point to the sidewalk.

It's pretty easy to accidentally do this because the editor automatically snaps points like this to nearby lines. If you notice this happen, you can use the undo functionality to undo the snap. You can also right-click the point you added and use the "Extract" function to pull it off the line. I did it for you in this case.
