Can't save the UserDefinedName to the camera

[alon-ba]

Describe what you want to implement and what the issue & the steps to reproduce it are:

I try to set a custom name to the camera, using SetUserDefinedName():

from pypylon import pylon  # version 4.1.0

baslers = pylon.TlFactory.GetInstance().EnumerateDevices()
first_basler = baslers[0]
first_basler.GetUserDefinedName()       # returns an empty string
first_basler.SetUserDefinedName("My_Basler")
first_basler.GetUserDefinedName()       # returns "My_Basler"

But it has nothing to do with the real camera!
It only modifies the python object.
How do I commit this name to the camera?

Is your camera operational in Basler pylon viewer on your platform

Yes

Hardware setup used

MacOS 14.6.1 (23G93)

MacBook Air M3

Camera(s) used

you snippet doesn't work:

tl_factory = py.TlFactory.GetInstance() for dev in tl_factory.EnumerateDevices():
                                            ^^^

you need to open the camera object and then set the userdefine name to the camera object.

@SMA2016a
Could you please write a snippet, how would you do that?
Because i have tried it, and it didn't work for me.

[SMA2016a]

sure,

camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice())
camera.Open()
camera.DeviceUserID.Value="mycamea"
camera.DeviceReset.Execute()

@SMA2016a
Thank you very much 🙏🏼

It actually raises two questions for me -

1. Is the reset mandatory? or just to make a point, to show that the property persists?
2. What is the different between DeviceUserId and UserDefinedName?

[SMA2016a]

1. a USB camera requires a reset to take over the new setting but not the GigE. Since I do not know which camera you have, I reset the camera.
2. The GeniCam Node name is DeviceUserId. Cameras parameter names are defined according to GeniCam naming conversion. UserDefinedName is just used in device object in pylon only.
