Aliexpress cheap doorbell "ubox" integration

I’v found a tag in the battery tray of the camera, it has a QR code with the device id and some characters (look like a password). I don’t know if someone know how to scane camera ip for open ports?

nmap scans for open ports. By the way that is the second time you have told us about the QR code and password, but you have never told us where the QR code points to or what the password is.

Hi, I used Nmap will the cam is on. Only one port is open :23.
The QR code juste give the Device UID, nothing else.

port 23 is usually telnet (by default anyway, god knows what the manufacturer has done)

So does telnet connect?

No I didn’t try.
