Display image from a camera in a UI component

Greetings!
I have a project in which I have the need to display images from a second camera in a UI component as a panel, for example. The idea is that it works like a screen on a monitor. In the scene will exist the main camera and one or two secondary cameras in the same scene but showing different environments.
I have been searching the internet for solutions, but so far I have not been successful. How do I achieve this? What tutorials can you tell me to help me solve this problem?

 

Just render the secondary camera into a RenderTexture, and then use that RT with a RawImage in your UI.

 

worked perfectly. Thank you.

 

Seems like a great approach, but I just added the RT with a RawImage in my UI and get nothing. Has something changed in how Unity approaches this?

 

What about just adding a second Game tab, then in the second camera object switch the Target display from Display 1 to Display 2, and switch the second Game tab to show Display 2? This way you get two tabs with two different cameras.
