I've been able to do firmare updates on some of my older Moultrie cams to make them compatible with newer computers. Just depends on the model.
I also tried a whole bunch of those cheap Amazon cams. Most turned out to work fairly well but I've noticed I only get a season or so out of most before they zonk out. What usually happens is they start losing time then eventually rest themselves over & over. It's especially annoying when I leave some cams out for months at a time without checking, only to find great pics but no reliable reference for time & date. Now I'm back to store bought cams, specifically Browning (thanks BSK for posting all those incredible videos
). It's worth it to me to have reliability. I run cams year round. They got to have staying power.
