OBS Studio with 3 Canon Cameras for Webinars?

[kdeleon]

Hi i'm searching for a sollution to use 3 or more Cameras (same Brand) with OBS.

My current Equipment right now is the following:

Perspective 1 Camera Trainer 1:
Canon EOR 80D with EOS Webcam Utility via USB

Perspective 2 Camera Trainer 2:
Webcam Logitec

Perspective 3 Camera Products Top down:
Webcam conference

For a more consitant look I wanna use for all perspectives the same Camera or at least the same Brand. For a test I tried to use another Canon Camera a Canon EOS m50 for the second Trainer but it doesn't work. The cameras are using the same Driver and i'm not able to choose 2x the EOS Webcam Camera in OBS.
Do I have to use a Camlink Adapter for the second Camera? If yes can I use a second Camlink for the 3rd Camera? Do I see then the 2 different Camlinks in the Hardware over OBS?

Thank you in Advance deleon

You will need to use capture devices (like the Camlink) for the DSLRs, yes. The EOS utility is mostly a preview, and is very low-quality compared to the actual HDMI video output.

Actual Camlinks support multiple units on one system. Many of the cheap no-name chinese knockoff capture cards do not, and can only be used one-per-system.

Do also be aware that if you use USB devices (like the Camlink) USB bus bandwidth is finite; you will need to make sure that each capture device is on a separate USB host controller (multiple USB ports are driven off the same controller, most times). This may require buying a USB expansion card. In multi-camera systems as described, it tends to be more efficient and streamlined to use a multi-port capture card instead, like this Magewell 4-port card: https://www.amazon.com/dp/B0178DV064
