Trisynchronous Motion

Welcome to the PTZOptics forum(s)!


This thread has been created for end users to discuss the topic of PTZOptics working on Trisynchronus Motion for preset recall.


Please make sure to respect the experience level(s) of all users at all times when posting within our forums or your account may have access removed.



Currently PTZOptics provide a very standard form of robotic camera movement when recalling presets.


Please provide any thoughts or feelings on the potential addition of a camera, or cameras, with the capability to provide a form of trisynchronus motion for preset recalls.

Can you elaborate on what motors you use?  

The PTZOptics units use Stepper motors for their PTZ movement. 

Hi.  I came across this thread last week and thought I'd do some testing.  The Motion Sync feature works great in some circumstances, but goes haywire (super fast speed) in others.  Here's a 45-second video that shows moving between the same PT coordinates, but with a different starting Z.  The first two movements are nice and smooth.  The 3rd gives you whiplash.  Seems like there's a math bug in the firmware.

@Michael I agree i have seen this several times as well.. Best i can tell the Motion Sync feature uses the zoom position to weight the P-T motion. If the zoom position is the same between two presets it goes wild. The solution is to hit a wide shot ALWAYS between tighter shots. 

@Tripp - I'd call that a workaround, but not a solution!  Given that we have a 20x camera on the back wall and all the action is way up in front, pulling back to a wide show between presets isn't practical.  I love the Motion Sync feature when it works, and look forward to someone fixing the math/algorithm in the firmware.  As a friend of mine would say ... "I'll bet a burger that there's a divide-by-zero error in there somewhere!"

@Michael: I did some retry and experienced the same. I guess the cause is some division by zero in the algorithm.
