Would you mind sharing your Rule Config for the Target Filter Max/Min size, and Tracking Target Size Ratio? I'm trying to figure this out and you have shed some light into this because my tracking used to go zoom in, them literally look up the sky and straight down like the camera literally rolled it's eyes at me lol. So now i'm trying to get this dialed in... thank you!
I have had good success with this one. I am sure there are some cheaper ones, but this one has been solid.

2.1 - Daytime Video
All, here is the first set of videos, this being the daytime Auto Tracking test. As I mention in the video, while the cam is good out of the box it does to to overshoot the target and miss the lock, hence quicker, shorter caps up front.
You know I like to dial in the image and the cam for better performanceTherefore near the end of the video I tweak the image setting more, change up the IVS and tracking target parameters and get a much more optimal, pinpointed target acquisition and lock for the entirety of the tracking time.
Take a look
2.2 Nightime Video
All
Here are some night clips from the 59232. Tweaked the image and pulled both 1/100 & 1/125 clips for you. As I always mention, taking time to tweak your IVS, image and target for the scene/FOV is a necessity in any security system BUT even more critical with PTZ’s. Just remember that none of these pro cams are plug and play and you won’t go wrong.
In this cameras case, tweaking image, rules, target, combined with low sensor noise produces very manageable grain which allows you to preserve a great image. You’ll also notice that on this sensor the noise is a crawl rather than sensor pulse and while both can be mitigated when setting cams up, the crawl always produces a more ‘enjoyable result’ as it requires less noise reduction and other tweaks to counter a pulse.
In these clips I purposefully keep NR relatively low and target tracking to medium to close. Allows the camera to adjust for movement without losing target while keeping sharpness of the image and is key to acquisition and continued tracking. Every one of these clips tracked for the entirety of the tracking time (tried many) and only returned to preset when that time limit was reached. There is a very slight delay in focus shift (foreground to background) which is not a a big deal at all as it corrects quickly but thought I would mentioned it for completeness and will see if this is the same in the latest FW.
Enjoy !
Could you share how you setup IVS rules to switch on autotracking?
I think if you did stop for about 15 seconds then PTZ camear would lose tracking.
I'll cover this again in the next PTZ review I do so you can see how to dial in but I do mention how to set for continued and consistent optimal auto tracking in other reviews I did such as the 49225 etc
I'm also have the problem with PTZ autotracking SD6AL433XA-HNR .
During autotracking when I person stops more 10 seconds the camera loses autotracking.
The second problem sport camera interupts current PTZ autotracking.
Could you explain how configure IVS rules for spot and PTZ cameras so that spot camera doesn't bother PTZ autotracking process?
That is one of the big requests LOL. Once the object stops, there are no IVS rules in place, so it doesn't know what to start tracking so it stops tracking.
That is why the spotter cams are so important to help guide and point it the right way if someone stops or it loses track.
Here is a great post by @bigredfish showing that in action when the PTZ stops tracking and then reengages due to a spotter cam.
Another "That camera is following me" clip
At least they had a good chuckle over it....
You can usually get it to not loose tracking so quickly if you change the target ratio a bit or turn PFA off, and I think this thing learns LOL. If the target ratio is too large, it will miss faster moving objects and lose tracking faster when an object stops.
My 49225 when I first got it would immediately lose track if someone stopped. Now it will hold longer than 10 seconds if someone stops.
I do think they learn though as my Dahua PTZ seems to linger on for 10 seconds or so. Part of that can be by not having it zoom in so tight that you don't give it much to work with. Mine zooms in tight enough that I can see the whole body, so when they stop for their dog doing its business, there is usually a tapping foot or something that keeps it tracking.
Here is how to setup spotter cams. I do not think with an NVR you can tell it to ignore a spotter cam if the PTZ is in active autotracking mode, but you can with Blue Iris.
Using Spotter Cameras to direct a PTZ where to look in an NVR or Blue Iris and setting a spotter cam as a priority in Blue Iris
We get this question from time to time, so I thought with the recent addition to BI, it made sense to have a thread we can point to. Previously in BI, if you had more than one spotter cam, you could not make one a priority, so if spotter cam #1 triggered the PTZ and it starts tracking and...

@wittaj beat me to it 
All PTZ's lose tracking if a target moves out of view or stops and is still after 10 seconds or so. Not much you can do about that. Any given scene can be dialed in a bit using target ratio (I find 30-40 works well for my scenes), but at some point it will lose track and return to whatever preset is programmed.
On the 2nd question, spotter cameras triggering the PTZ will always override* any tracking in progress.

Just a clarification for those that find this later.
Currently within an NVR a spotter cam triggering the PTZ will always override any tracking in progress.
In Blue Iris, you can tell it to ignore additional spotter cam requests if it is actively tracking based on another spotter cam.

Good point, yes I was referring to use of an NVR. Didnt know about that in BI. Thx
