Camera Nebula Smart Kit

I have a Creality Ender 3 V3 SE printer. At the beginning of April I received the Nebula Smart Kit from Aliexpress. The installation went without any problems. Everything works except the camera. The camera is not detected. I configured WiFi, connected it to the cloud… But the camera is not detected and the blue LED does not light up. Who can tell me if the problem is in the camera or in the settings?

I have 2 of those cameras and they simply connected, no real setting up. I would see if I could get a replacement.

I tried to connect the camera to the computer. It is not defined at all. It looks like the problem is in the hardware itself.
