I've been using a couple of these cameras for about a year, and just ordered two more.The good parts:The color (in daylight of course) is brilliant and true and pictures are crisp and very life-like. They obey all ptz commands flawlessly. While they don't rotate continuously, you still have 360 degree vision. Night vision is stunning, but let me add that in both my installations I am not depending on the built-in IR lighting. I have separate IR lights mounted on the same poles as the cameras. Night detail is almost as crisp as during the day.The bad parts:After nearly a year, both units took in heavy water during a downpour. I'm not talking about condensation - I mean liquid water. I had to take both units down, remove the dome and POUR out water. I am not sure where it entered, but on remounting the units, I decided to cover both so that they are no longer exposed to direct rain. So far, so good. But no matter how I've cleaned the plastic domes, I now have serious blurring and areas of whiteout during night vision. This is having taken great care not to get finger prints etc on the domes. I've scoured YouTube for suggestions but to date nothing has helped.Presets: the original units did not do presets. I'm not sure if this was because they weren't loaded with a microSD. I've now installed memory so I will see if they can now store presets and do patrols.Summary:Overall, an excellent investment for the price. I've taken one star off for the water problem.
