I have done this on a few installs but i set it up on the dvr side.
1. Setup all your presets up first, then access the tours menu on the dvr / PTZ dome
2. there should be settings there to select within the tour which preset to goto and how long to set the dwell time bedore moving to the next one.
3. some domes also have setting for the speed of which to goto preset.
4. once done, start the tour by the DVR/Keyboard and that should do it..
