For those have signal issues, the good news is that MG582-8M and MG882K-8M have enhanced antennas that boost signal strength by 3db (2x more range from the cell sevice base station). Both have native solar charger support, so that you check your camera much less often.
I would love to see someone post a real-world (not photoshoped) pic from one of these units. Every pic I've ever seen fro the cellular units are not very good quality. I think they would be fine for inventory purposes but for me they fall short at the photo quality level. Blessings........Pastorjim
Here are a few of the transmitted sample pictures from SG550M-8M All pic qualities of Scoutguard/Bolyguard wireless cameras about same:
