video doorbell telnet access

[gralfj]

Hi , just bought from Aliexpress a Tuya video doorbell.
i am happy with it but translation is nasty, and I would change some things if possible, so I decided to take a look and try to see indide de FS.
After few tries, voilà now I have this NMAP output and got access with root user

Starting Nmap 7.94SVN ( https://nmap.org ) at 2025-06-19 20:52 CEST Nmap scan report for 6c60ebc916cc (192.168.0.46) Host is up (0.0095s latency). Not shown: 997 closed tcp ports (conn-refused) PORT STATE SERVICE 21/tcp open ftp 23/tcp open telnet 6668/tcp open irc

Have to say that my skills are those up there, I am a beginner level user, but I could follow instructions if anyone knows and wants to take advantage of the device and take info from it.

do you think I can extract something useful from this?
