It depends. Do you think you might be recovering the camera(s) in the future and want to get it the covering back off? Rubber cement should be easy to take off again, it won't hold very strongly if you need that. Contact cement would work for sure, but it is gonna really hold on there. Lots of scraping and cleaning if you want to do a complete recover later. There's many glues that will work if you plan on just gluing what is coming off and leaving it at that.
Elmer's is probably too weak. I imagine the paper is pretty brittle on the cameras too. Before gluing it back down, you might want to set the camera in a bathroom and run the shower on H for a while and hope the paper becomes more bendable so it doesn't break off where it's bent.
