Thanks for your answer and apologizing for the missing details. I am using openHAB 2.4.0-1 (Release Build) as openhabian system on a Raspberry Pi. Release = Raspbian GNU/Linux 10 (buster) Kernel = Linux 4.19.75-v7l+ Platform = Raspberry Pi 4 Model B Rev 1.1 Thanks for the hint, I will now work …

You will most likely be asked to update OpenHAB or at least that binding to the latest rest release 2.5 Milestone 4. 2.4 is considered quite old now. The 2.5 release was delayed and is now expected at the end of this year.

From searching, I would guess the problem is the IP Camera binding. You could be running an ancient version of OpenHAB.

Since you provide no information about your system that is probably the best information you can get here.
