Review - Dahua SD49225XA-HNR 2MP 25x Starlight + IR PTZ AI Camera with Deep IVS & SMD Plus
- Thread starter Wildcat_1
- Start date
Are there any other differences between the XA and the XB that you can tell, besides the 4MP? Trying to decide between the two right now and order one. Thank you!
Well, I've mostly solved my video clip editing issue, but w/ a workaround and not directly in PSS - still working on that. I have 3 clips showing the range of tracking situations (in my location) and will post them tomorrow. I remain quite pleased with the outcome and the clips demonstrate different object sizes and tracking around and past obstacles, including one large bush that I was sure would stump the camera, but....??? Tomorrow.
As for differences btwn the XA/XB I can only say that I'm content with the night performance of the XB (4MP) that I bought. The supposed knock on it was that 4MP is less capable in low light/night. So far, that has not been an issue for me and I do like the higher res images in daytime of 2560 X 1440p. Based on my limited experience so far, I would say it depends on whether you find the night images sufficient (I do) and whether the increased resolution in daytime is of value (for me, yes). Wildcat has written extensively (post 641 especially) on the 2MP vs 4MP capabilities vs sensor size and night ability - I'd strongly suggest you read that before making any decision.

I got the 2 daylight vids up, so I'll post those now. The night vid will be tomorrow. I was especially interested in how the cam followed the bike and the truck when approaching and passing a very large bush. These are down rez'd to 1080p from 1440p.
Oops...sorry about that, fixed. Thanks
Here's the night video, but reviewing it, I realized I hadn't dialed in the exposure/noise settings as much as I had t thought. The tracking was what I was looking for. I have since changed the noise/exposure/ir settings and the image should improve in the future.

Do you have a might time clip in colour please as I would like to compare it to the SD49225-XA like I have.
Here is a few night clips forced colour.

Mine is now set to Tracking Size 45 and If I put that to Max 100 it would zoom in closer quicker but usually ends up loosing the tracking object as it goes out the FOV quickly.
I can't remember where I have my tracking size setup right now, but I believe it is somewhere around 40-50 as well. Above 50 I found it zoomed in to much. Vehicles it wasn't as bad, but on humans in would zoom in to far and you'd just get a good shot of their chest.
I'm thinking for fast moving objects it zooms in slower than for slow moving objects. It is kind of finicky, as it will zoom in better on the slow moving objects, but when they stop moving it is very quick to lose tracking and go back to the preset location. It would be nice if it had a time delay option, so that after it loses tracking it takes X seconds to come back home, or it shouldn't be so quick to dump the auto tracking when movement stops. They could just stop moving for a second, camera pans back to its home position, and then never picks them up again.

Sorry could be a rookie question, but does this thing have audio (XA model)? All the videos posted are silent. Thanks everyone!

Most all settings are best setup in the camera directly.
Yes, info is in the spec sheet in the first post. You would need to add a microphone.
Would you be willing to share those setting? Noob here trying to get a baseline for my 4mp ptz.
Thanks!
Can anyone put up a picture of this mounted to their home? I know there are a few, but they are very close up, so I can't get scale. I'm trying to figure out the most unobtrusive area to place it on my home. Thank you in advance!!!
For anyone that owns this cam, would it be possible when you have free time to post images of objects at each of the DORI Distances? I believe 25x will be sufficient for me, but I would like to actually see what this looks like. Much appreciated!
