I have not worked with that Logitech camera, but have with another. Matlab is generally good at giving you access to the camera properties. You can find out which properties you can easily control in Matlab using the following code:

vidobj = videoinput('winvideo', 1);
selectedsrc = getselectedsource(vidobj);
% to show the prooerties you can control do the following
get(selectedsrc)

This gives the following information on the Command Window:

General Settings:
Parent = [1x1 videoinput]
Selected = on
SourceName = input1
Tag =
Type = videosource

Device Specific Properties:
BacklightCompensation = on
Brightness = 128
Contrast = 32
Exposure = -7
ExposureMode = auto
FrameRate = 30.0000
Gain = 0
Saturation = 32
Sharpness = 48
WhiteBalance = 4000
WhiteBalanceMode = auto

Once you have that list, changing properties is just a matter of finding out what the relavant ranges are for each property. It might be that your camera gives you access to the motorized Pan/Tilt angles in this property list. If so, you can simply set these to the desired states. For example, to set the frame rate of the camera to 25 FPS, you would use:

set(selectedsrc, 'FrameRate', '25.0000');
