Motorized Pan Tilt Product Suggestions

[flyinglentris]

I searched the site and found no hits on this topic, so ...

There might not be many members here who have had experience with these devices, but maybe a couple who can suggest good products. What I am looking for is a motorized pan/tilt that can be controlled via computer connection, either cabled, IR or Wifi. It should allow setup of angles to allow overlaps and timer functions to set both intervals between shots and durations when bulb shots are within 360 degrees and tilts of +/- 5 to 60 degrees as necessary. It should also allow triggering the shutter. Not all of the devices I have researched satisfy all of these prerequisites.

Suggestions appreciated.
