    Dahua keeps dropping Frames Per SEcond (FPS) to around 5 - 6 even though it's programmed to do 25.

    Hi, I don't think it's the exposure, as when we restart the camera, the FPS returns to normal.

    Dahua keeps dropping Frames Per SEcond (FPS) to around 5 - 6 even though it's programmed to do 25.

    Just an update. We just checked now, our client often has power outages and switches to a generator. Could it be that? Generators are known for not providing continuous power.

    Dahua keeps dropping Frames Per SEcond (FPS) to around 5 - 6 even though it's programmed to do 25.

    Ok, thanks! Just to debug more. I'm using LAN, so bandwidth wouldn't be an issue, right? Does that mean it's power?

    Dahua keeps dropping Frames Per SEcond (FPS) to around 5 - 6 even though it's programmed to do 25.

    I ingest the feed through Python. And that shows 5-6. Also, it's streaming to Youtube, and that also then shows that very stuttery 5-6 FPS. But as soon as I switch it off and on, both go back to smooth 25fps

    Dahua keeps dropping Frames Per SEcond (FPS) to around 5 - 6 even though it's programmed to do 25.

    My Dahua keeps dropping FPS to around 5-6, even though it's programmed to do 25. If I restart the camera, it goes back to normal. I have another camera of the exact same model, and it never does it. What causes this? And how to fix it? Device Model DH-SD6AL445GB-HNV-IR ONVIF Version...

    How to center bounding box using 3D move without changing zoom with the Dahua HTTP API.

    Hi All, For those who are interested, I actually found a perfect solution. You give the camera a 0x0 box to center. Then the camera moves to exactly that spot without zooming in.

    How to center bounding box using 3D move without changing zoom with the Dahua HTTP API.

    Hi, I’m controlling a Dahua PTZ through the HTTP CGI interface. The moveDirectly command works well for centering a bounding box from image coordinates, but it always performs a zoom-in so the selected rectangle fills the frame. I need to keep the current zoom level exactly as it is, just...

    PTZ IR Mode On Manual Focus Doesn't Remember Focus Point

    Hi all, I've come up with something that worked perfectly for me last night. I wrote a script that automatically runs through all of my night-time PTZ presets and updates them once the camera has fully moved and settled focus. For each preset it: Sends a GotoPreset command to move the...

    PTZ IR Mode On Manual Focus Doesn't Remember Focus Point

    @bigredfish Yeah, the camera is running IR at night, and most of the night presets are zoomed close to max (20–25x). The reflective marker idea won't work sadly, as it's a national park, and so we can't place tapes there. :( When I get the cam's status from the API, the focus numbers doesn't...

    PTZ IR Mode On Manual Focus Doesn't Remember Focus Point

    Thanks again, everyone, for all the input so far. It’s been really helpful! But, just to clarify my original question, if I manually focus the image perfectly at night and then save that preset, why does the camera not recall that exact focus position later, so that it doesn’t have to re-run...

    PTZ IR Mode On Manual Focus Doesn't Remember Focus Point

    The auto focus after reducing DNS is working a lot better! But, there are still a few presets where it auto focuses out of focus. Is there something wrong with the manual focus that it doesn't work every night? Would a cloudy night vs a clear night change the focal point?

    PTZ IR Mode On Manual Focus Doesn't Remember Focus Point

    How do I make the "speed" or "step" save at the slow speed? Every time I switch to a new page, it goes back to the default.

    Are Hot Pixels Fixable? How to?

    Hi, Have 2 PTZ set up. One is 3 months old, the other, around 3 weeks or so. Same model. Dahua - DH-SD6CE225DB-HNY 2MP 25x Startlight IR Network PTZ Camera Every evening, even before IR mode switches on, but definitely as the sun begins to set, I start seeing these white pixels. They are in...

    PTZ IR Mode On Manual Focus Doesn't Remember Focus Point

    So, just to understand the algorithm, when DNR is high, the picture is just so smooth, the autofocus algorithm struggles to find sharp edges? And when the speed is high, it is more likely to overshoot past the right focal point, and therefore, it will struggle to find the focal point? Thanks again!

    PTZ IR Mode On Manual Focus Doesn't Remember Focus Point

    Ah, ok I see it. It was on the middle point. So I've changed it to slow: I've also reduced the DNRs to a much lower level. Anything lower than that, it's very grainy. Should I do semi-auto? Or, what does that mean? But, it's actually a lot better already!! Auto focus is working a lot...

    What's 1 step instead of 20? Where do I change this? Here's an example of when I saved the preset: Then 2 nights later:

    Hi, Yip, I saved it at night, and I have 2 presets per location, one at day light and other at night.

    PTZ IR Mode On Manual Focus Doesn't Remember Focus Point

    Hi, I have around 40 presets at night 100m+ away. I have saved the preset when the picture was in focus. However, every night, it is out of focus again. Not terribly out of focus, but the picture is not sharp. And if I set it to auto focus, it goes WAY out of focus. What do you suggest? I'm...
