Tom,
You might consider using a TV antenna rotor, the degree of motion may not be
as fine as you desire, but I'm sure you could modify the controls to work
off a relay. Also, dlink has a couple cameras that not only have audio in,
but with an amp'd speaker can have audio out. They do have limited
connections to control a relay, I think one or 2. Using a couple micro
switches you could also control the rotation to prevent more than 360
degrees, but I believe the TV rotor also prevents this.
Another thought is you may be able to use the pan and tilt circuitry to
control a TV rotor? These can be controlled over Ethernet or through a
wireless camera connection.

Subject: [WISPA] Motor controlled rotating poles
For the longest time, I wanted to build a solution to do the following,
from each of our Master Cell Sites....
1) Rotate a IP Camera 360 deg (remotely over an IP connection)
2) Rotate a Pole with a Trango Fox 5800SU on it 360 deg (remotely over IP
connection).
The purpose is two fold....
When Link quality severally degrades for a short period, either packet
loss or rssi,
1) To discover/view when there is a third party worker working on the roof
of our cell site.
(Who may be standing in front of antennas periodically or testing
gear that interfers without getting pre-approved)
2) To do a spectrum site survey, on the fly in any direction, to find the
least noisy channel, WITHOUT taking the primary sector antenna down
(offline).
By having the radio and the camera on the same pole, it would help confirm
which direction we were pointing exactly when doing the survey. One of the
other requirements is that it won't turn more that 360 in one direction to
prevent cable CAT5 breaking, and to ahve a refference of the starting
point in deg, calibrated to a known direction (north 0 deg?). What would
REALLY be cool, is if it had a speaker out put on the camera, so I could
yell at the worker standing in front of my antenna :-). I'm aware that
some camera may have an output for controlling a relay or servo motor, as
some solutions/platforms exist to mount and rotate a single camera
attached. Preferably, I'd like a solution that could rotate the pole
itself. Everything of course would need to be outdoor survivable, and
strong enough that the pole would stay errect and safe at 200-300 feet up.
My thought is that maybe the controls could be initiated from the IP
Camera connections, If I found a rotating platform/pole mount.
Are there any mechanical hobbyists out there, that might suggest the most
cost effective way to accomplish this?
(My goal is lowest cost, lowest cost, lowest cost, so I can afford to
replicate the solution at about 20 locations)
