Hello Teachers,
I want to know what does 'mount' mean in the following sentence:

"...Security officials at Tampa's Raymond James Stadium hoped to do so by using machines that recognize faces.
Each face seen by the gate-mounted cameras was compared to the data in local and federal law-enforcement computer systems..."
And please tell me which of the meaning of the below link has the meaning of "mount"?!

The phrase "gate-mounted" means that the cameras are attached to the gate(s).

Well, of course, all of them have the meaning of mount, but you are referring to definition 4.
