My analog ptz seen in my avatar is still working in its 5th year of operation. It's much like the huisun, in fact it's called an insun- undoubtedly produced by the same wizards, lol. It's been through major blizzards, a hurricane, tropical storm, and a little storm you all may know as super storm sandy. I never bought into the wiper thing. Mine has primitive auto tracking just like this one too. The key to my longevity success I believe to be not actually moving it a ton through the years. I turned off auto tracking and along the way had it do scans and preset tours, but it's residential. I never saw the need to keep it hopping all around on a constant basis. The power brick died early on but a new one has lasted years. Two things have happened from age. One is the inside of the dome has degraded to a nasty cloudy mess on the ir side but thankfully not on the lens side. The clear faces of these things will do that over time, evidence of inferior build. Make sure you know how to pull the face dome off for cleaning on the inside along the way. The other thing is the ir module. I get blinking on lower strength ir settings so I mostly have to keep it brighter even on full zoom out. Other than that it's still working great. Just realize that at any time you may have to replace. I'm considering fixed instead of ptz when I'm ready.
