Who Knows A Lot About Home Security Cameras for The Driveway? Recommendations.

I have had Aiwit brand cameras for a few years now, they are ok, and solar powered so I don't have to worry about the power being disconnected. They are linked to my cell phone and until recently they worked pretty well. The problem now is they keep giving me an error message saying there is no micro SD card, therefore they do not record, but still show live video/audio. I have new SD cards coming, so I will see if that solves the problem. If not, they were only about $100 each, so we'll look for new ones.
