    what is the "General" firmware?

    See the screenshot below from Dahua's website. What is the "General" firmware as opposed to the "other" firmware? Normally Andy's firmware file names match the "other" one below. Is the "General" one just a subset, or is that an international one, or ??? What does it mean that, using the example...

    what is the "MCU" firmware on Dahua's website?

    First, I have NOT (ever) installed any "MCU" firmware and don't intend to until/unless I understand it and see value in it, and hence the reason for this post. See the screenshot below from Dahua's website for the awesome SD5A425XA-HNR camera. In the past, I have generally only installed the...

    When new Dahua cameras only support IE in 2023, should we look elsewhere?

    When Dahua introduces new camera models that only support Internet Explorer with a 32-bit ActiveX plug-in, at what point should we show them the same lack of respect & support they give us by going with another camera manufacturer with comparable camera models? I just received a new Dahua...

    Dahua ONVIF authentication errors (particularly with Blue Iris)

    For several months now I have noticed many thousands of errors per camera in the Blue Iris log such as: 1 6/19/2023 12:00:08.009 AM office-door Events: subscription 8000ffff 1 6/19/2023 12:00:08.685 AM paseo-cardero Events: subscription 8000ffff 1 6/19/2023 12:00:09.819 AM gate Events...

    lowering camera mount position on a wall

    I have a Dahua turret camera currently mounted to a junction box on the wall. Unfortunately there is a beam & gutter on the side that prevents the camera from seeing horizontally in that direction. Ideally I would like to lower the camera position 6-8 inches (more is fine) without making another...

    100% DeepStack timeouts after BI update (including reverting to earlier versions)

    I decided to upgrade BlueIris from a version before any of the CodeProject work had been done to a more recent version. I did NOT even attempt to install CodeProject.AI because I had read somewhere in these forums that BI would use whichever was installed. When I launch BI (I went ahead and...

    which setting causes 5241E-Z12E blur with even slow motion?

    The picture below has been cropped but otherwise has not been edited, even though it looks like someone used photo-editing software to blur the license plate on the left. I can't control the cars that drive by, so I manually put an old license plate and circular reflector on the right side of...

    How to mount cameras with cable on the corner (e.g. IPC-HDBW4231F-E2-M)

    I bought several new cameras from Andy, including one of the dual lens/sensor cameras, IPC-HDBW4231F-E2-M. Oddly, and perhaps unfortunately, the cable protrudes on the corner of the back of the camera (rather than the center). Has someone else mounted one of these with a junction box? If so, how...

    what is the network type = fast/slow setting?

    I didn't realize until just now that the "type" field on the TCP/IP settings screen is actually a toggle. Clicking it will change the value to/from "Slow" and "Fast". See the screenshot below in which the "Slow" appears to be static text, but it is not. It's just a poorly displayed radio...

    IPC-T5442T-ZEB disables ability to paste into password

    Hey @EMPIRETECANDY , I got one of your IPC-T5442T-ZEB cameras off Amazon. On both Mac & PC, using the Chrome browser, it seems that I cannot paste a password into the login screen, either with a right-click "paste" or "paste as plain text" selection or using ctrl-v. When doing any of these...

    how do you use PTZ auto-track/tour/scan/pattern/pan/time tasks?

    I have a DH-SD59225U-HNI and would like to hear how the rest of you use some of the various PTZ functions on any model of camera, whether it be at home just for fun or for more serious security. This forum has many posts with people setting up the auto-tracking, but how/when do people use the...

    SmartPSS zoom on playback timeline without a mouse scrollwheel

    For those who don't already know this, SmartPSS allows you to zoom in on the playback timeline through the use of the scroll wheel on your mouse while hovering the mouse directly over the timeline (doesn't work unless mouse is over the timeline!). I do not believe this is in any documentation...

    How does OSD "North" & "Coordinates" really work?

    I have a DH-SD59225U-HNI but I'm hopeful this setting exists on other PTZ models as well. How does the "North" setting work for the on screen display, and as it relates to the display of pan-tilt "coordinates"? See the image below for the settings. I'm particularly curious about the "N" button...

    IPC-HDW4831EM-ASE stops recording every day, overwrite not working??

    I have a few IPC-HDW4831EM-ASE that I bought from Andy. Every day they stop recording, and typically re-start at midnight even though I don't have the camera set to reboot until 2am. I have a feeling that the "Disk Full: Overwrite" setting may not be working, but I don't know how to prove it or...

    24x7 recording of sub stream, then main stream w/IVR or motion?

    I have a Dahua 4k IPC-HDW4831EM-ASE. I love it, but have realized the limitations of a 128GB card (generally the largest "Endurance" card available) when recording 4k video (even w/H.265) 24x7. That fills a 128GB card in a little more than a day, requiring the "Auto Delete Files" setting to be...
