I've made some new more exhaustive and precise tests.
As the target, I've used a fireball moving along a 15 meter trajectory in a second at constant speed, a speed high enough to expose any possible latency in the response of the cameras tracking/movement.
I have used 3 cameras, all them arranged and/or moving along a parallel 4 meter off the target's trajectory:
1) Tracking the object and fixed at a mid-point of the trajectory
2) Tracking the object and fixed at the starting point of the trajectory
3) Tracking and moving along a parallel trajectory to that of the target,
The takes for the three cameras are shown in this clip: https://drive.google...dVZWWDFacTJjc3M
And a video showing the arrangement and movement of the target and the cameras: https://drive.google...aWJSdzBDWm1COHM
Finally, an archive with the test movie itself: https://drive.google...M3lXTE1wODNqRG8
- In every test, the camera has not problem to track correctly the target, keeping this in the designed point of the field of view.
- Panning (rotation of the camera) seems to have no latency at all and the tracking is immediate.
- Travelling (displacement of the camera), on the other hand, seems to have a certain latency, ie, requires a time for speeding up and slowing to stop at the end of the trajectory: you can see in the second video, that when the target starts moving the camera is left behind, then accelerates and even manages to overtake it.
So it looks like, at least when moving at high speeds, the travelling movement is not uniform, if that was your question. But again, in every case the target was perfectly tracked all the time.
