Whatever camera's You decide on be sure to ge/buyt the appropriate cables and locks for them,You don't want the new camera's to be stolen right off the bat!Most of the trail camera's have metal lock boxes that fit their certain models..I highly recomend protecting your investments for getting stolen.
The different trail camera's I would reccomend.Start off with a few trail camera's and once You find one that works the best or You like to operate more than the others You can get more of them as needed!
Cuddeback Capture (Flash) trail camera.
Bushnell Trophy Camera (Bone Collector) Camo trail camera (IR No-flash Camera)
Moultrie D55 IR Trail Camera or the Moultrie I-60 IR trail camera.
