    Hi Nx Team

    Any update on this? Not sure how to troubleshoot this issue further

    Hi Jason K,

    I have requested the device as a virtual loan, from the Axis HQ for further investigation. I assume it should become available this week.

    In the meantime;

    1. Did you check if you are using the latest firmware?
    2. Did you try to do a factory default?
    3. If Onvif disabled for the device?

    If we fail to resolve or reproduce it with the virtual loan device, would it be possible to connect to your device?
    If so, we'll transfer this topic into a support ticket, so you can share the connection details privately.

    Hi Norman 

    Thanks for the feedback.
    I can confirm all of the above has been checked.
    Device on latest firmware, ONVIF if disabled, and device was factory defaulted.

    You're welcome to connect to my device for further troubleshooting.

    Hi Jason K,

    At this moment, I'll wait for the virtual loan, but if that doesn't resolve the issue, I'll let you know.

    Hi Jason K,

    Today I received access to the Axis Virtual Loan camera, and I was able to check the advanced PTZ performance.

    In THIS video, you can see the behavior I experienced. To be honest, I didn't notice major deviations, but I think I understand the issue you encountered and noticed increased overshooting when I zoom in to the max more than when I zoomed out.

    Unfortunately this behavior cannot be optimized since we are bound to the API of Axis for the PTZ coordinates. In general the behavior is more noticeable when you are zoomed in and make large movements.

    For your information, below the model number and firmware I have used:

    Hi Norman

    Thank you for your efforts. 
    I did notice similar behavior in your test, and you are correct that the issue is more pronounced at greater zoom levels. 

    If this is an issue that is purely on the Axis side, I will open a ticket with them. 
    Confirming that Nx uses the VAPIX API to integrate with these Axis devices?

    Hi Jason,

    Regarding:

    Confirming that Nx uses the VAPIX API to integrate with these Axis devices?

    See THIS support article. Yes, we use VAPIX for the integration.
    That being said, I do not know if this can be improved. To be honest I doubt it.
    I have asked if we could improve something by adding more numbers behind the comma for the coordinates that are used for PTZ control, and I was told, we cannot make it more granular with the API. 

    And for most cameras there is always a more or less noticeable over- or undershoot when using coordinates to control the PTZ. For Onvif PTZ camera, we can influence and thus reduce this a little for many models, but for Axis we can't do anything. That being said, some cameras will always over- or undershoot.
