Something like this?
YESS, thats exactly what I was thinking of... 
Only... for me it would need to be @ least 1m long...
If you have 2 OctoPrint devices they each have their own IP address that is unique. You can have one camera on Pi that is at 8080, and a second camera on a second Pi also at 8080. Your addresses might look like this:
http://192.168.1.11:8080
http://192.168.1.12:8080
They are different because of the IP address of the Pi they are connected to. If you put more than one camera on the same IP then the ports must be different, like this:
http://192.168.1.11:8080
http://192.168.1.11:8081
http://192.168.1.11:8082
Make sense?
Yes thanks, that makes sense! ThatĀ“s what I expected to hear, anyway whe you are working yourself towards a solution you want to avoid any possible issues as itĀ“s not to easy anyways, but the setup works meanwhile like you said.
After I have built the raspberry pi into itĀ“s location the transfer rates have somewhat dropped - compared to just having it laying beside the printer...
WiFi or wired? If all you did is move an existing, working device from one location to another then the issue is the connectivity:
If WiFi - check the old and new locations. I suspect the new location has a lower signal.
If wired - replace the CAT5/6 network cable
WiFi @ the moment. The difference is: before the raspberry Pi was lying beside the printer, open - no case - just the pimoroni4 square attached to it.
Now it is built into the housing of the prusa display attached to the printer. This has taken away some of the bandwith by now. After extensively testing I will move it to a location where I now the signal is good.
And maybee I will wire them up...
Wired is always the way to go if you have the option, and wireless only if you must. This is true for any connected devices, not just the Pi.

Yep, thatĀ“s true...
@Slacker
If we speak of going wired: This drops another few questions for me:
1 where to configure LAN acces in octoprint?
2 Are the wireless and LAN connection active parallel then?
3 If necessary: where to disable the wireless card on raspberry pi?
would you be so kind to shine some light on this for me?
The wired connection is already configured for DHCP so normally, nothing needs to be done except plugin the cable.
The wired and wireless connections can be active in parallel. They normally have different IP addresses.
Here's a link to instructions for disabling the wireless adapter.
thanks @ b-morgan,
for the link on disabling WiFi. Had the funny thing going, that even I commented out the wlan credentials in /boot/octopi-wpa-supplicant.txt the raspi was connected via LAN and Wlan. In my case things where a bit more difficult, because iĀ“ve set both connections to static ipĀ“s...
Iv`e got another question regarding the camera: I tried to rotate the video by 90Ā° clockwise, but it does not work. Can someone please tell me what I am doing wrong? I put the following line into /boot/camera-streamer/libcamera.conf:
OPTIONS='--camera-properties="Rotation=90"'
OPTIONS='--camera-options="Rotation=90"'
neither of them seems to work...
please assist
