Thanks for tagging me in @wittaj. @Nunofya you are good with the 5A425, that had (and still does) Auto Tracking from the factory so you would be good there. The 49225 S2 you definitely want to stay away from as this one (as I mentioned in my other threads) will have NO auto tracking nor can it be re-enabled. So if you go for a 5A425 (not 49225) now you will be ok. Alternatively though, I expect to see some other updates to the PTZ lines this year so if you're not in a rush, I would wait it out a few months and certainly by mid this year expect there to be some refreshed PTZ models that may be worth looking at. Let me know with any other questions
