[General] There's an ultra-red temperature machine at every entrance....

Hi.

I went to a shopping mall yesterday. I noticed that the mall has three doors/entrances. [STRIKE]for people to going into it[/STRIKE]. At each entrance, there's a machine that can detect people's temperature. I wrote "There's an ultra-red temperature machine at every entrance of the mall".

I wonder if the sentence is natural.

It is also called a thermal scanner.

There's an infrared thermometer at every entrance of the mall.

Is the above sentence natural in my context now?

Yes. I'd use "every entrance to the mall" (or, in BrE, "shopping centre") but "of" isn't wrong.
