what command should I run for knowing if the system can detect my cam ?
I have this message and my cam is connected...
Traceback (most recent call last):

Hello julienbayle , are you using the OAK PoE device? Otherwise, if USB, I would suggest switching USB cable (to USB3 cable), as that's the most common reason for the issue you are describing.
We are on OAK-D
We tried with or without PSU adapter.
In the studio, everything was working fine with USB only (no adapter)
In the exhibition room, it doesn't work anymore.
Cam seems to heat a lot. I hope it has not been damaged.
Did you already experience this ?
Hello julienbayle , have you tried changing the USB cable - or better yet, use the one from studio that was working? You don't need the PSU, as usually host computers (laptop/pc/rpi etc.) can supply enough power. Regarding heating; the device can heat up to 60C (docs here), and no device was ever damaged due to heat (except if you take off enclosure/heatsink and run it).
