I sprang for a new camera to replace the POS Reolink I bought years ago, before I knew any better. A Dahua T5442TM-AS. They're both 4MP with the Reostink having a varifocal lens while the Dahua has a fixed, 3.6mm, lens. Pardon the pun, but the difference is like night and day. I can leave the Dahua in color mode at night with just the ambient light from the street lights. The Reostink was, basically, blind at night even with its own IR lghts on and a couple of auxiliary IRs I installed trying to get a decent picture from it. The difference is sensor size and sensor quality.
