On linux, ssh1 may be able to connect where ssh cannot. We hope this issue - and the security warnings - will be solved by the upcoming 0.4.x update.

The error basically means the connection to the camera failed on port 22.

Can you try to use ssh to connect to the camera? PuTTY is a great windows tool for that. Or use BASH directly if you're on windows 10.
From there on troubleshooting is much easier.
Good day. I had the same problem as a user above. Now I connected to camera via SSH as a root. What can/should I do now in order to enable the script provided above to work? (The main task for me is to get the images/videos from the camera when I need via python script, if this information is necessary)

Run the script on the computer, not the camera. You don't have to log in via SSH separately.  The script will do that for you.
Logging in via ssh might be useful as a debugging step if the script isn't working.

The problem is that the script is not working :) Therefore I tried to connect by SSH, but now I don't know how to use it to solve initial problem.

Also, this is the only way I was able to connect to camera via SSH:
ssh root@192.168.12.1 -o Kexalgorithms=+diffie-hellman-group1-sha1 -o Ciphers=+aes128-cbc

The script is trying to connect to connect to '192.168.12.21' instead of '192.168.12.1'.
Was your script edited to use 21 instead of 1 for the last number?

I just noticed it) After changing IP to 192.168.12.1 there occured another error:
copying latest video to host
Traceback (most recent call last):
  File "get_latest_video.py", line 37, in <module>
    copy_video(cam, serial, localdir)
NameError: name 'serial' is not defined

How should I define that serial?

serial should just be removed from the script.  Open the script in a text editor and change the line containing the world 'serial' to:
copy_video(cam, localdir)
