but do not forget the so-called "vandal dome" cameras which look like a 
dome, but are only static/fixed types.
Or the 360° cameras which look like a big raindrop only ...

Ask yourself the question "What info do I get with this distinction?"
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.

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 
So I think it is not - at least I won't trust these attributes. ;-)
Tag the manufacturer and the model instead. ;-)
