I want to provide a certificate for my IP cam.
A router with an activated Port Forwarding to my IP cam (let’s say https://rtps.example.com:9900 -> 192.168.1.3:443
An IP cam (D-Link DCS-5222L) with the internal IP 192.168.1.3
The IP cam provides a Web interface, in which I can generate a certificate request. For this I have to capture some certificate relevant values. After I entered all these values I can download the certificate request:
My first question now is: Which values I have to enter in all these fields, in order they are valid for a Let’s Encrypt certificate?
If I download the certificate request in the next step (Filename: server_csr) what shall I do with this request now? Finally I should have a valid Certificate file, which I can upload (again via Web interface of the IP cam - there is no ssh or telnet access) to the IP cam. But my problem is, that I really don’t have an idea, how can I achieve this. Any help would be nice!
PS: I think, I have do renew this certificate manully all 60 - 90 days in my enviroment, right?
Thanks in advance,
