Just an update on this camera from my point of view.
This camera has done wonderfully in the midwest winter. Handled -50f, winds, rain, sleet, snow, etc... all like a champ.
This ptz also tracks MUCH better than my 49225. The mini has newer algorithms, and I'm not sure what else, but the tracking is incredible.
The only two down sides for me, is the 1/2.8 4mp lens at night. The 2mp lens on the 49225 shows a better picture at night with little to no lighting. However, being that I have my mini over my driveway, the picture at night is still great.
The other is the dome can develop spots from sideways rain/snow/sleet. Hence, position this baby either in a area protected from the elements, or at least able to easily get to for cleaning.
The smaller fixture is also a definite bonus for me. While it's easy to see, if you're looking for cameras, the majority of people just aren't going to see the camera.
Overall, a great ptz, for the right conditions. As I mentioned in a earlier post, I'll most likely purchase another one this spring for porch coverage.
