Recommended PTZ camera for continuous motion

Hi experts,

I would like to get your opinion and recommendation about a good PTZ camera.

1st major requirement is to be able to move smoothly and continuously between several pre recorded presets. i.e. I would like to capture 3 points, then let the camera move from P1, to P2, to P3 with a defined speed and acceleration.

2nd most important requirement is to adjust to speed and location/zoom changes: for example, to be able to control the camera (by code, not interactively), to move to points "near" the recorded points (e.g. 1 deg left from P1 with speed that is x1.2 faster than the recorded speed).

All is done via code, except first points capturing.

I found out that Axis Communication and Sony cameras cannot do it – both force delays and stop when reaching P1, P2, P3.

Any idea if there are other brands that may support mentioned requirements?

Thanks,

Dan
