There are also concealed cameras with small lenses, covering a limited field of view from a fixed angle. This type of camera is likely to be noticed only if you see a reflection from the lens.

I think, the only info is a "Maybe ..." A 'normal' mapper can not see the difference between a real PTZ-Dome or a vandal-dome camera - you may even do not see, in which direction the latter is mounted. Also not the difference between a fixed mounted static camera and a fixed mounted zoom camera. > * Would this be a relevant attribute to tag? I think it is. > My conclusion: You can not easily map the correct type of camera - and you can not estimate the surveyed area or details without the technical data of the camera. So I think it is not - at least I won't trust these attributes. ;-) Tag the manufacturer and the model instead. ;-) _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging -- John F.
