Sounds like you need a NVR upgrade . The SD49225XA-HNR is not years old it's a pretty new camera in the 2020 catalogue.
Dahua SD49225XA-HNR is KING for me and not seen anything better to date especially from its performance vs price....less than 300 bucks considering ordering another just as a spare. :)
Can I ask where you see that price? Thinking about picking up one or two of these

I'm doing everything I can NOT to order one after seeing yours and @Parley 's posts. I've spend a bunch on other cam upgrades this month and I have two decent PTZ's already but they are not near your 4/3 ones. The one thing holding me back so far (other than the cost of one) is the minimum zoom level - it's 16mm right? How do you find that? Do you have any fully zoomed out shots to give an idea of the zoom at that level? My current SD6CE225U-HNI is 4.8mm (63 degrees) - 120mm. Your cam would be the equivalent, I think, of mine going up to over 300mm! I think it may be overkill for me but I really want the 4/3 sensor in 4k. Wish there was a lower end 4/3 PTZ, I'd really be all over that one.

I've actually just talked myself down from getting yours as I look at the view from mine at 4.8mm - I see a perfect view of my yard width (actually could go a bit wider even) so bumping the min. view up to 16mm would really cut down my yard overview. I don't think I have a 50ft high mounting spot either.

LOL, HA HA speaking of talking yourself out. I was doing that too for months now. I was trying to hold on to that since I have so many cameras on my house. It look @ times Fort Knox probably have less security LOL. That 4/3 PTZ With AI Is expensive but worth every penny.

So, I had my friend pickup one last month since he asked me which one was really better at night for his environment and he got the camera couple of days ago. So tested his 4/3 ptz both on his street and then we tested it on my street. We were both blown away with the results on how it can even see stars at night :| (Again your Lighting condition/settings of camera depends but its a pretty good one.

So at that point, I was like hell I am getting one. Now where I am going to install it yet I don't even know LOL. I just wanted one cause its badass LOL. So that brings your point for the zoom. I currently have two other PTZ for Zoom and FOV if I wanna have the whole view. Which are the SD8A840WA-HNF & the SD6CE245U-HNI so they can do those jobs.. still for me.

The 4/3 Will be basically A night time auto track for people lurking around. I have other cams which will be like covering the front yard and so on.. if they need to be zoomed out then those cams are covering it already. Now on my street lights are really limited so the reason I be installing this to get like description of suspects in future to pick up what color clothes / cars etc..


Here is a night shot from 4/3..

I know parley has shared some in the past with video to see performance at night. Again it also keep in mind it depends on how your light conditions are and what setting your cam is set for.. etc.. But it is a solid one for sure :) Cannot wait to get mine will do some comparison video maybe when I get with my 1 1.8 ptz and 4/3 :)

Parley, I know you said your AI Ptz is learning and getting better. I am gonna guess that is part of the Dahua NVR.. my PTZ AI Tracking on 1 1.8 is really good but, I don't think mine is learning anything and I think the reason been is that It needs a DAHUA NVR and it just does not work on the learning part with BI...

You sound like me. I'm impulsive - 22+ cams around my place so far with two decent (but only 1/2.8") PTZ's. I have the "I want the badass cameras" syndrome too :cool: . Should start a thread about "What's the badass cameras out there now?"!!! I live near the USA border and I see their cameras up the big poles and wonder to myself "Can I get their badass cameras too? I wonder what model they use?". LOLOLOL. Or even, "what's the badass cameras on the spy satellite? Can Andy get that one?" :lmao:

Actually I am using a Hikvision NVR. In fact all 3 of my NVR's are Hikvision. They work well with the Dahua cameras. If need be I can hook them up directly to my network by unplugging the camera from the NVR and then plug it into my network. I have to change the address back and forth but that is no big deal.

Thank you Parley. No I dont wanna have you get to disconnect stuff LOL I think its the NVR capabilities to learn and not so much built in alone.. The only reason I say that is .. I have the Tree and when My PTZ is auto tracking once the person is like behind that tree for a split sec.. when auto track is tracking it looses them most of the times.. Now I think that is just because it lost the person so it thinks they are gone.. it does not wait even for a sec or two and cuts out there. It has not learned that so far.. That is why I think mine is not learning.. with Deep AI but that is not a biggie since Auto tracking on these DEEP AI one is really really good to begin with..

I should say what you see in the picture is the marine layer. It will burn off shortly. However no smoke.
