Seeking Alternative Methods for Controlling Zoom on Fixed AXIS Cameras via ONVIF

[MoonfoxGames]

I am currently developing an application that interfaces with PTZ cameras using the ONVIF protocol, and so far, the integration has been successful, especially in controlling pan, tilt, and zoom functionalities.

However, I've encountered a challenge when attempting to apply similar controls to fixed cameras, specifically models like the AXIS P1448-LE, which do not support PTZ functionality out of the box. This limitation has been a significant hurdle in achieving zoom control on such cameras.

For context, here is one of the ONVIF commands I've been utilizing and recommended for zoom control on PTZ cameras:

<tt:AbsoluteZoomPositionSpace>
 <tt:SpaceURI>
 http://www.onvif.org/ver10/tptz/ZoomSpaces/PositionGenericSpace
 </tt:SpaceURI>
 <tt:Xrange>
 <tt:Min>0.0</tt:Min>
 <tt:Max>1.0</tt:Max>
 </tt:Xrange>
</tt:AbsoluteZoomPositionSpace>

This method has proven ineffective with the AXIS P1448-LE due to the apparent lack of ONVIF PTZ support being a fixed camera. Is there an alternative approach to manipulate the zoom level—specifically, adjusting the 'wide' and 'tele' values without the conventional PTZ commands.

Could anyone shed some light on alternative methods or APIs that could facilitate zoom control on fixed cameras?
Thank you

Answers to your questions will most often come from the community, from developers like yourself. You will, from time to time, find that Axis employees answers some of the questions, but this is not a guarantee. Think of the discussion forum as a complement to other support channels, not a replacement to any of them.

If your question remains unanswered for a period of time, please revisit it to see whether it can be improved by following the guidelines listed in Axis support guidelines.

Fixed camera does not PTZ command in ONVIF, even in VAPIX zoom in/out is not listed， the reason is the mechanisam of P14/P32 is not designed to frequent zoom in/out as a PTZ camera, it is just for easier cofiguration and installation purpose. If you frequent zoom in/out with command, it will damage the camera.

If you insist to get the command to control the zoom in/out, you can use wireshark to capture the command while control zoom in/out via camera web GUI. But remembed, it is just for easier cofiguration and installation purpose.

Thank you rocky, that makes sense.
