Whether there is a camera that would be compatible with the card you are using in your trailcam would probably be a guess. Maybe you could try it out on some borrowed cameras to see if it will work. As far as the card readers downloading to your computer, I think most of them do. At the very least, they all have a cord to attach to your television. www.chasingame.com did a whole section on various card readers and their capabilities. Log onto their website and see if there is one that fulfills your needs. Another option might be one of those digital picture frames they sell at Walmart and many other places. Just make sure you get one that will operate on battery power. I have used my wife's to do that before. One advantage with those are they come in so many different screen sizes. Hope this helps.
