"Gear", in this case, meaning the medium the photos are stored on. The headline (and image in the post) try to make it sound like thousands of dollars of camera equipment is on the line here, when really we're talking about SD cards. It's a modern equivalent of saying that if you violate the contract, you have to give us the film and/or negatives.

I doubt the "authorized agents" would distinguish a camera from its SD card. I can't imagine that said agents would be anyone other than hired private security.

This is probably a "cover you ass" clause in case there's an altercation between security and the photographer. It's easy to imagine a low paid security guy resorting to saying "I told you you can't take pictures here" and smashing the camera.
