5.8 Power-Up
Routine
After power is connected to the dome, the dome performs the following homing routine.
1.
After a few seconds, the camera lens tilts up into the housing and eyeball
assembly.
2.
The lens tilts downs until it looks at the floor.
3.
Eyeball pans slowly.
4.
Lens tilts up 90° (home position).
Once the lens is in its home position, you can use the controller to call up the camera
and control it.
5.9 Synchronizing
Domes
To prevent picture rolling when switching from camera to camera, all domes can be
synchronized to a 50 or 60 Hz AC source.
