Looking at a 2342, 2332, or 2322 in 2.8 to cover my front yard. I already have a 2332 covering my drive and left side of yard and plan on mounting another cam side-by-side to that one pointing to the right. Essentially a dual cam set up with each facing opposite directions to capture a near 180 degree view with maybe just a bit of overlap in the center. Anyone see a problem in doing so? Secondly, I have (2) 2MP LTS turrets (essentially 2322s) and their low light IR capabilities are a bit better (less grainy picture) than my 2332 3MP cam. I read on here that 2MP cams often do better in low light than 3MP and that seems to be my experience as well. So if you were me, would you go 2,3, or 4 MP to cover right side of yard? How does the 4MP cam compare to the 2 and 3mp hiks for low light image quality? Should i match the left and right facing cams...in good reason to do so?
