Samsung’s SPD-1000 speed dome camera
If you’re currently on a lookout for an interior speed dome camera that is meant for indoor use, the Samsung SPD-1000 ought to fit the bill very nicely. It comes with a 10x optical A/F zoom lens and provides accurate focusing whenever zoomed in. In fact, even vivid images can be captured at 100x zoom, and with 128 preset settings for automatic monitoring, you will always get the clearest picture possible. Monitoring can be set to large areas and different sectors (a maximum of 6). No idea if this is suited for art galleries and museums (they probably have a much more sophisticated system in place), but it would do mighty fine in a huge mansion.
