+### How to sign in into camera via SSH?
+
+`ssh root@<camera_ip_address>`
+
+There is no password by default.
+
+### How to sign in into camera web UI?
+
+Open http://<camera_ip_address>:85/ and sign in using default username _admin_ and default password _12345_.
+You will be asked to change the password after successful login. __Please note, it will also change your ssh root password!__
+
+### How to find information about the camera hardware and software?
+
+Sign in on camera via `ssh` and run `ipctool`.
+
+### I don't see ipctool on camera. Why?
+
+You don't see it because initially it is not there, but there is a shell command of the same name. _(Since it's a shell command, it won't work from Web Console in web UI. Sign in to the camera via SSH and run the command in there.)_ When you run this command, the latest available version of `ipctool` utility gets downloaded into `/tmp/` directory and runs from there. Since the utility resides in `/tmp/`, it won't survive a reboot, thus won't take any useful space on the camera afterwards.
+
+If you need to know what's in the command, search for `ipctool` in `/etc/profile` file.

 ### How to configure ssh session authorization by key
 
-__On the camera__: Open an ssh session and create a non-empty password for the root user. By default, in our firmware
-the root user does not have a password. Keep in a mind that after you have created a password, all subsequent new ssh sessions 
-will require authorization with this password until the moment you set up the public key authorization,
-as well as when trying to log in from a computer which does not povides such key. Don't forget it!
+__On the camera__: Sign in into web UI on port 85 of your camera.
