Unable to make Zoom in / Zoom out work

[doucettom]

Hi,

I am trying to make an ONVIF cam Action buttons. I've been able to make pan/tilt work using this how-to but so far, I've been unable to make the zoom in/zoom out buttons work reliably. Thus, I'd need some help if someone already done this. My camera is ONVIF-compliant, this really looks like a lack of Python coding skills (or, in all honesty, scripting skills in general)

TIA

It might help to post what script(s) you are using for zoom in/out and Action Buttons... Can you generate the zoom command outside of motionEye? Does zoom work on your camera in an app? I have some d-link cameras that were sold as PTZ (pan-tilt-zoom) but were only pan-tilt and zoom was a function of software only.

Don't forget the rest of my questions...

An add: What OS are you doing this in?

[doucettom]

Pan/tilt/Zoom are available in the Camera's web UI but they're javascript buttons. This is the camera: https://www.amazon.com/Hikvision-Compatible-18xOptical-Security-4818X-IZ/dp/B089M9WR7L I'm using Ubuntu Server 20.04.3

This is what the PTZ controls of the Cam web ui are looking like.

This is the PTZ configuration menu.
