    Roll of PTFE tape with a Dahua PTZ, why?

    Why has the installation kit for a Dahua PTZ camera come with a roll of PTFE tape? It's almost like the sort I would use to seal plumbing threads . I say almost because it's rather thinner than normal rolls of PTFE tape I've already got. The camera came with a bracket that's not threaded. I...

    Lightening Bolts fasteners available in UK, in the USA too?

    Yes I know it was surprisingly tough brick, I've never know brick as tough as this to drill into. It didn't hep that I needed to drill in deeper than usual. If I'd had a heavier SDS electric drill with a much stronger hammer action it might have been like a knife through butter. That electric...

    Dahua Camera Firmware Update

    Am I right in assuming that now with the latest Dahua camera updates there's no going back to older firmware, because of 2.0 security and it being encrypted firmware? If so we become dependent on Dahua continuing to develop firmware and bug fixes for our existing cameras, that quite possibly...

    Windows 11 starting to appear on the horizon

    https://www.microsoft.com/en-gb/windows/windows-11 https://www.windowscentral.com/windows-11 I'm an on-off Windows Insider so may be offered to run W11 before it's goes full time, on a PC that I don't use for BI. I'd be interested to read of folks views of W11, and additionaly any likely issue...

    NEW SD59225U-HNI Latest New Firmware SD-Eos_MultiLang_PN_Stream3_V2.812.0000007.0.R.210706

    I went with this FW upgrade on my DH-SD50225U-HNI, mainly to avoid needing a browser plugin, no problems encountered with the upgrade. The results, camera works OK with W10+BI with its dual NIC, routers LAN and camera LAN, I also have a Hikvision NVR on my camera LAN. However, using the Virtual...

    NEW SD59225U-HNI Latest New Firmware SD-Eos_MultiLang_PN_Stream3_V2.812.0000007.0.R.210706

    Andy, your now edited first post has an apparent link to dropbox with FW 20210708, though currently it appears to be a link to 210706, that's the same as the title and the same a looney2ns has kindly made available. Is there a new FW 210708 or was this just a typo? My as yet still to be...

    Blue Iris digital zoom issue

    Well I've mostly solved this again. I'd had a similar issue in April 2020 and looking back over my previous thread fenderman has again provided most of the answer. For some unknown reason when I looked in camera settings of several of my fixed cameras, in tab PTZ/Control the box Enable...

    Blue Iris digital zoom issue

    All of my camera's appear to have the same settings, none have "Solo selected camera" but if I do, the chosen camera becomes full screen. On those cameras affected I can Zoom in with the scroll wheel but I am unable to move to left or right. If I want this I have to return to a 3x3 display of...

    Blue Iris digital zoom issue

    On my 3x3 BI display if without a double click I select one of the camera's video feeds just by placing the mouse pointer over that camera and not double clicking, I can use the scroll wheel to zoom in and move to which part of zoomed in image to have a closer look at. All this seems normal. If...

    At my wits end with this software.

    You have my sympathy Gizmo. I came back from holiday recently and BI had been updated. I lost the functionality of a double click enlarging a camera's view, then I found a couple of cameras weren't triggering clips as they had before, somehow the settings had been changed, probably upgraded...

    Many thanks folks, I've got the double click back working, and learnt a bit more out BlueIris. I'll also give a thumbs up to IPCT

    Double left click no longer enlarges a chosen camera's view

    I'm on "No automatic updates" but have just updated to 5.4.7.6 x64 too, sadly there's no reversion to the previous BI feature of a left quick double mouse click enlarging a single camera's view, rather strange.

    Double left click no longer enlarges a chosen camera's view

    I'm just back from a few days holiday, BI on 5.4.7.5 x64 (30/5/2021), a double left click doesn't enlarge a chosen camera's view as it did before, instead at the top the word "Paused" appears in place of the camera number that BI has given to the camera. Have I missed something and there's a way...

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    I've has another look at the listings for the Microseven M7WP-MIC which I'd earlier rejected because of its large size. I now see different dimensions being quoted, 16.8 x 8.6 x1 cm on one website, 4.75 x 7.75 x 2 ins on the Microseven website, 6.6 x 3.4 x 0.4 ins on Amazon.com However much I...

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    I'm sure the Microseven would fit the bill but access to the soffit where I would need to go is very awkward, I know because I spent ages getting some flexible conduit through for the camera's cables. Thanks for your help but I'll stick with my plan to reinvent the wheel which is easy enough.

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    I decided to work further on this until I run out of steam, there's something about the balance between work and effort v potential benefit and rewards. On a previous test on our living room carpet I separated the microphone insert from the camera using about 3 feet of screened cable and the...

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    I did some more audio tests today with this PTZ camera. The best of my electret microphones is a AOM-6738L made by PUI, 9.7mm dia, 6.7mm in height. There was no apparent advantage in adding another small electret microphone in parallel. The audio output from this electret insert is modest at...

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    Update I've had an opportunity today to connect in turn a couple of electret condenser microphone inserts to the Audio-In wires on my Dahua PTZ DH-SD50225U-HNI. I've not as yet changed the IP I've been using, the camera's IP is still on default into a W10 PC outputting to a TV as monitor in our...

    Auto updates no longer work

    Though I've been on "All available major and minor updates" for many months, BI here is running on Release 5.3.7.12 x64 (05/01/2021), which my BI PC appears to be stuck on. I'm not sure why BI hasn't already updated to at least 5.3.9.17 (26/03/2021), billed as the "latest critical or highly...

    IPC-HDW5231R-ZE Rhea V2.800.0000016.0.R.200430 Latest new firmware

    It may have been in this thread that I noticed the firmware files Andy had a link to and a member, were not of the same size. Probably unrelated but after a firmware update I had to do a bricked camera recovery on my DH-IPC-HDW5231R-ZE, it's not something I want to repeat again, not just the...

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    Thanks for the correction looney2ns I checked again, the Dahua datasheet has this camera supporting PoE+, though in the short time I've run the camera on its 24v mains power supply it does run somewhat warm. I'll be choosing to power it from it's 24V AC brick rather than from a PoE+ port on my...

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    I can confirm that my DH-SD50225U-HNI will deliver audio over IP. From my workshop I could only find an old crystal microphone insert but despite it's high impedance it sort of worked. I found there's 2v on the Audio-In wires so there might be enough to enable a cheap electret capacitor...

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    Thanks, an interesting suggestion of the PoE splitter, I hadn't appreciated what these splitters can do, I see a suggested use is to a power a raspberry Pi. In my experience I've often had to upgrade their power supply. I've got one running Kodi and in the past one I set up as a VPN server...

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    This PTZ needs 24V AC, it's not POE. Incidentally my Hikvision NVR does have audio input and output sockets though as often the case the instruction manual gives little further info.

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    Thanks all I'm getting a clearer idea. Next I'll have to decided if it's that important to add a microphone, probably not considering the extra work involved and the limited space in the junction box.

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    Thanks folks. I've been sidetracked because I've been basing my expectations of audio from this large PTZ on my experience with my Dahua mini PTZ a DH-SD1A203T-GN which does have a built in microphone. I'm aware the internal motor noise of a PTZ can drown out any external sounds, though with my...

    Dahua PTZ DH-SD50225U-HNI should audio over IP be available?

    I'm in the process of commissioning this camera before it's mounted outside at the rear of the property, this camera it looking like it's a no for audio over IP. Manufactured in 2017-07 the camera has audio in and out wires which I assume are analogue. BI hasn't found IP audio, neither did VLC...

    New to me Dahua camera already initialised

    I went for the reset button and Dahua Config still reported the camera was initialized. Choosing the web interface this did require me to set a new password, so I'm satisfied. I've got to choose next which firmware to update onto it now, Dahua's older or Andy's latest. So it looking like...

    New to me Dahua camera already initialised

    Some while ago, probably 2018 I bought a Dahua PTZ DH-SD50225U-HNI probably on eBay UK. Everything checks out as new and unused, the label on the box, camera manufactured in 7/2017, properly packed and all appropriate accessories. I'm now getting round to installing it at the rear of our...
