As far as I know, with the exception of the older Cuddes and the Reconyx, they all pretty much use the sd card. If you have no experience with trailcams, you can go to a website,
www.chasingame.com and read reviews on nearly every camera made.
www.trailcampro.com is also a good place for reviews on most current cams. It is also a great place to purchase cameras. IMHO, you need to spend around $200.00 to get a good quality unit. Cameras in that group, and all these use the sd card, include the Moultrie I-40, Cuddeback Capture, Bushnell Trophycam, Scoutguard, and some of the Spypoint cameras. Sometimes, you can pick up a good deal on a used camera over on Archerytalk. Hope this helps.
