As others have pointed out, the bulls really start moving around once the rut starts, and that bull you might have had on camera all summer is suddenly gone, while an area where you never picked up a bull is now moose central.
I would say the primary benefit of a few cameras would be to 1: get a sense of what areas hold moose (generally) and what areas don’t, look for similar habitat to those areas you seem to be getting moose on your cameras. 2: get a sense of the size of the bulls in the unit (to help you figure out what is or is not a shooter in your mind). 3: you will learn some of the road systems in the process. 4. You might get lucky and place a camera and get a lot of cow activity - cows move a lot less than the bulls (they should be in essentially the same area during the summer as they are during the rut) and if you can find a cow hotspot you are likely to find some bulls - at least while the rut is hot.
A few years ago I had a cow followed by 3 nice shooter bulls parade right through less than 40 yards in front of my deer blind in GMU 117. When a cow is in heat, the bulls will come from miles.
