I believe that IP would be best since that monitored end may not be stationary.
So there is nothing available for a PTZ that has built-in 360 motion detectors?
Here is what I am thinking: A PTZ on a post, in a field, facing North. Something walks near it from East to South. The "motion detectors" pick it up and the camera turns and tracks it until it leaves it's detection zone.
Have I been watching too many movies, or would that be possible?
Please pardon my ignorance on the subject.
Thanks for the help so far!
