My previous cameras were 720P and worked fine. It's 1080P (2M) and (as you'd expect) has a much nicer picture. Also, newer 2M cameras seem to stay in color mode with a significantly darker subject area. The top image is a 720P camera that is already in "Night mode" and the bottom image is a 1080P/2M camera that is still in color mode. The second screenshot was taken after I turned off the porch lights, but the image is still much sharper (as expected). Best of all, these higher-resolution cameras cost about the same price, or even less, than replacements for older ones.
