Frimware is usually a chipset followed by a download of software to run the chipset. It can also be just one or the other. Some chips need a software update to turn up some features of the product after the manufacturer discovers a flaw in the product. Clear as mud now, right???
I am intentionally stupid about trail cameras because I am a photographer and we compete but what I do know is "I don't want to have to update my trail cameras" I just want them to work. That said, I don't want to go out and have to buy new ones all the time either so if I stop fighting the manufacture and do the "update" I get new life with same box. Is this what you guys are talking about? As it relates to trail cameras?
