Thanks, that is why I would like to get one and try it.
What I am doing right now to determine what I need/want, is to temporarily install either the 180 or the 5442, view it for a couple of days and nights, then replace it with the other one and see how that compares. (Except for the 2nd 180 that the wife decided she definitely wanted in a specific location and had me get).
I would like to get one of these and try it where one of the 180s currently is and see what the results are, or maybe even set it at the other end of the wall (about 25') and see how they compare side by side on the monitor for a couple of days and nights.
Since I didn't see the sensor info in my quick scan, the thing I was concerned about was the WiFi rather than wired ethernet.
My experience with the WiFi doorbell (Amcrest) was not good. I had a lot of times where a person was walking up to the doorbell, and it would get them at the far edge of sideway ~15' away, and then the next image would be them walking away from the door after putting the package down, and similar things. When I replaced the wifi doorbell with the VT02311R-WP, that problem disappeared.
I don't think it was router because it was very close to the door (~20') with only windows between them, and I can get good signal on my tablet much further away.
