Stick with the cheapest one you can afford, to tinker with. I have 16 highly rated Dahua cams but it took over a year to get this far (still gots a LPR camera to go!). I started off with 4.
Play with the 2431. Your primary concern is keeping eye on the driveway. If you fired up that camera system you bought from Costco, I hope you kept/saved some images or videos. Would like to see the comparison between Costco camera system and the
blue iris/dahua 2431's.
Later on, you can advance up the camera ladder in terms of quality of image, MP, Starlight+, multiple angles, high & low, etc. For now, play with that single camera and learn do's/don'ts of camera stuff. Gain knowledge. This camera stuff has some science to it
