    GetEvents error / "Events: subscription 8000ffff"

    A little investigation on my system: T5442TM and T5442T-ZE get continuous Event errors with ONVIF authentication enabled. T2431T, miniPTZ and 4K 180° are fine with authentication enabled. I didn't experience the issue at the time switch in March or November of last year.

    Any way to use surplus RAM ?

    When I repurposed the PC to run BI it only had 8 GB of RAM, so I decided to upgrade. Turned out that 32 GB was not much more $ than 16, so that's what I put in. The PC operates to my satisfaction but has so much unallocated memory. Is there any settings in Win10 or BI that I could tweak to...

    Worlds First Review - Dahua DH-IPC-PFW5849-A180-E2 - Dual Lens 180 Degree Full Color 4K (8MP Stitched) Camera

    Is there any way to get the day/night switch option to show up (as shown in the manual for "Working Mode")? Using the 12 month schedule seems lacking, particularly when sunrise/sunset times change from the beginning to the end of the month. Also, how's this going to work in March & November...

    Worlds First Review - Dahua DH-IPC-PFW5849-A180-E2 - Dual Lens 180 Degree Full Color 4K (8MP Stitched) Camera

    Good point on using BI for the MD. I've taken the advice of letting the cams do that, with good results overall. The cam is mounted on the soffit in front of a patio, so at about 7 feet high when within 10 feet, about a foot higher relative to things beyond that distance. At another location...

    Worlds First Review - Dahua DH-IPC-PFW5849-A180-E2 - Dual Lens 180 Degree Full Color 4K (8MP Stitched) Camera

    I'm dealing with an issue on this camera: With the wide view and great night vision, I'm trying to setup motion detection to "see" what animals may visit at night. I've setup IVS rules for capturing human intrusion in a side region and it works nicely. I created a motion detection area (not...

    Worlds First Review - Dahua DH-IPC-PFW5849-A180-E2 - Dual Lens 180 Degree Full Color 4K (8MP Stitched) Camera

    After I de-selected "General" it works! Now hitting Search brings up the recordings ("mountain" thumbnail) and everything works as expected. Prior to that, hitting Search popped up a brief message "No Data Available". When I was working on this yesterday, I had trouble with the storage page...

    Worlds First Review - Dahua DH-IPC-PFW5849-A180-E2 - Dual Lens 180 Degree Full Color 4K (8MP Stitched) Camera

    I am in the process of getting familiar with this camera. Thus far I've been astounded by how good the low light performance is - and I don't even need the illuminators! I have one problem that is stumping me though - I can't get it to record to the SD card (or at least play it back)...

    Privacy mask rectangular vs. free-form

    I'm dealing with this problem currently. Unfortunately the only cameras in my setup that allow "freeform" masking areas are the two 5442's. The 2431's, 3541F, and even the new 4KT-180 only allow rectangular areas. In my case I have the one 3541F setup at the side of my house to watch a gate...

    IVS not sending trigger to BI, but MD/SMD does - why?

    Sorry for the late response, but here is the link Andy sent to me: Firmware Select Download, then pulldown firmware. The file is: DH_IPC-HX2X4X-Taylor_MultiLang_PN_V2.840.0000000.8.R.221213 I upgraded all four of my 2431 cameras with this and IVS is working properly on them now. NOTE: This...

    What are my choices for fully-functional web browsers for Dahua cameras these days?

    Just a note: I (thought I had) disabled that darn IE_to_edge by renaming the BHO folder from "bho" to "bho_old", and it worked - until it renamed it back to "bho" 4 days later.

    How to view Dahua cameras without browser plugins

    Yep. In the chit-chat forum there's a thread with a workaround to stop the redirection (hijacking) of IE to Edge.

    Looks Like Internet Explorer Died Today

    Thanks for the tip! Last evening I got so far as knowing that the IEtoEdge thing was the culprit but didn't know how/where to neuter it. I changed that folder to BHO_OLD and IE is back, like you said.

    How to view Dahua cameras without browser plugins

    Looks like microsoft has begun rolling out edge updates that permanently disable IE as of feb.14th. I can no longer run IE - it now redirects to &#$@&#$ edge. Fortunately it looks like you can define sites/ip's for IE compatibility mode but they expire after a month (why?). This -seems- to be...

    IVS not sending trigger to BI, but MD/SMD does - why?

    Thanks to both of you. Man, the "End trigger.." fiield is right in front of my nose and I missed it! One thing that really helped my testing & troubleshooting was being able to view the camera recordings in IE with the IVS & detections enabled. Pretty neat. Adding a final update: It turns...

    IVS not sending trigger to BI, but MD/SMD does - why?

    After increasing it to 40 MB, it is working! I changed it back to 6 MB and it continued to work. Looking at the BI help file it mentions that the buffer can be increased up to 20MB, so that limit isn't a bug (even though you can enter larger numbers). I've now set the buffer to 20 MB. I...

    IVS not sending trigger to BI, but MD/SMD does - why?

    Hmmm. I increased it to 40 like you have. The 6 MB was just what it defaulted to. I will test it later tonight and report back tomorrow. I may have have found a small BI bug - using the ^ button on the "Recieve buffer" entry box, it tops out at 20. I was able to change it to 40 using the...

    IVS not sending trigger to BI, but MD/SMD does - why?

    Again thank you for the quick response. I only created the SMD for this test. I had already verified that SMD works as expected with BI. The "problem" is that when there is only the IVS rule/function enabled, Blue Iris doesn't seem to get the trigger and record it (but the camera does record...

    IVS not sending trigger to BI, but MD/SMD does - why?

    First, thanks for the informative reply. I've scoured and checked and verified that I have done everything you mentioned. I re-ran the "Find/Inspect" in BI and the output contains the line: "Has Event Services: /onvif/event_service" (and it does detect as generic. The thing that doesn't make...

    IVS not sending trigger to BI, but MD/SMD does - why?

    I'm in the early stages of learning a couple of Dahua cameras and using them on Blue Iris. I have encountered a puzzling issue with a IPC-T2431T-AS camera: I setup an IVS (intrusion) rule and when it triggered I get no recording on BI, but it DOES record the video on the micro SDcard (yes, IVS...

    Dahua IVS setup "Working Period" - Can't Edit?

    Ahhh. I was looking in the main menu and not finding it. Now, knowing it's on the machine I guess I'll find it and create a shortcut on the desktop. Added 1/23/23: IE up and running with plugin(s).

    Dahua IVS setup "Working Period" - Can't Edit?

    Thanks for the assistance. Between learning new networking subjects (opnsense, vpn setup), Blue Iris, and individual camera settings, it's been a gradual trudge up the hill but I'm gradually gaing altitude...

    Dahua IVS setup "Working Period" - Can't Edit?

    Followup: I think I kind of see how this setting works. To set a given day, on the chart click the click the "Setting" button on the right side of the given day. Then use the mouse to create segments on that bar, each will populate a period field in the lower half and the corresponding day of...

    Dahua IVS setup "Working Period" - Can't Edit?

    Hmmm. I'm actually using Firefox because I had read Edge & other chrome based browsers didn't work for IVS setup. I don't know if IE can still be downloaded (I never liked or used IE to be honest). I have been able to setup tripwire and intrusion on FF, btw. I notice that your screencaps...

    Dahua IVS setup "Working Period" - Can't Edit?

    It is connected to a PC running Blue Iris. Also, I do have an SD card installed to see if that had any effect (it didn't). Seems like simply bad or buggy UI to me. The reason I say that is because the uneditable "schedule" only shows SUN enabled, but the IVS event triggers BI and recording...

    Recommendation for a new Router

    This is what I'm doing. Opnsense on an old Lenovo thinkcentre with a 4-port Intel NIC installed. I then installed a second NIC on my BI pc that the cameras are connected to. The other port connects to my opnsense router. This way the constant cam activity isn't flowing through my router &...

    Dahua IPC-HDW2431TM-AS-S2 high failure rate (>50% within 18 months)

    Thanks for the heads up. I have 4 of this model, purchased here in November and they have s/n's beginning with '8'. Hopefully it was a single batch thathad this problem.
