    Review-Dahua/EmpireTech Dual lens IPC-HDBW5441F-AS-E2 (The Boobie Cam Upgrade)

    According to Dahua's spec sheet (IPC-HDBW5441F-AS-E2), the 3.6mm lens has only a 78 degree field of view (vs. 95 degree for the 2.8mm lens). I believe that implies you absolutely cannot get 180-degree field of view with the 3.6mm. If you see the walls on both sides, you'll have a gap in the...

    Review-Dahua/EmpireTech Dual lens IPC-HDBW5441F-AS-E2 (The Boobie Cam Upgrade)

    FYI, I have the 2.8mm lens and absolutely get 180 degree view, able to see the wall on both sides of the camera. With anything tighter than the 2.8mm lens, I don't know if that's possible. Having said that, there is a catch . . . In the image that @wittaj shared, be aware that the "shell"...

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

    For me, it was security. My "Security Baseline" was V1.4, and this is V2.0. What does that mean? I don't know and I don't expect Dahua to tell us. Was it necessary to upgrade? Perhaps not, since nothing for me was broken. Previously I was running firmware over 2 years old, decided to try it on...

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

    Yes, I have been successful using that firmware on 3x HDW5231R-ZE as well as 2x IPC-HDW4831EM-ASE and one IPC-HDW4231EM-ASE (all of which provide the same download on Dahua's site). All were successful BUT . . . I always try to remember to stop BI from recording during an update (so the camera...

    How much resolution is really needed for LPR

    I love this analysis and optimization for those who can benefit from it. Having said that, since we definitely have people new to LPR who aren't so technical and read these posts, I want to point out that if you are trying to capture license plates from 2 (or more!) lanes of traffic (as people...

    Review - Dahua/EmpireTech Full-Color 5MP IR & White Light IP Smart PT "Active Deterrence" Camera - SD2A500-GN-A-PV

    For me, they are just hanging. I don't remember having a better option but I'll have to look again to know whether I was being lazy or if that was the only option.

    @XDRDX I believe the people in your images are simply too small, especially the ones across the street. I also believe the image processing doesn’t happen on a full 4k image, at least not by default, even if that’s what the camera supports. At least with the DeepStack implementation, I believe...

    Review-Dahua/EmpireTech Dual lens IPC-HDBW5441F-AS-E2 (The Boobie Cam Upgrade)

    I'm running H.265 w/5fps, showing 4608 as the max "reference bit rate", so that's what I have both streams set at on 3 of these cameras and all run smooth. That's only half of your 8196, and it's H.265 which seemed to be ok for you, but thought I'd give it as another point of reference. For me...

    Review - Dahua/EmpireTech Full-Color 5MP IR & White Light IP Smart PT "Active Deterrence" Camera - SD2A500-GN-A-PV

    Ah (implying thank you!), I like your thinking that I may have something configured differently on my camera, but I don't have that setting on this camera (see images below). I can only enable p2p. Do you have that option in this camera model, in which case we might have different firmware? My...

    Review - Dahua/EmpireTech Full-Color 5MP IR & White Light IP Smart PT "Active Deterrence" Camera - SD2A500-GN-A-PV

    Unfortunately changing only the ONVIF source did not change the behavior. I did re-inspect (which of course changes the camera make back to generic onvif) and then reset the camera make, model, & stream profiles. The events are still coming. Now that I've stared at the log screen for enough...

    Review - Dahua/EmpireTech Full-Color 5MP IR & White Light IP Smart PT "Active Deterrence" Camera - SD2A500-GN-A-PV

    I've had this camera for a while now with BlueIris, generally working fine, configured with the same great instructions described in the first post. However, when I look at the BlueIris log information in the status window, I see this camera generating tens of thousands of "Events: subscription...

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

    I did two things at once so I'm not sure which solved the problem, but I deleted all the redis temporary dump.rdb files (which had dates on them) and I re-installed DeepStack. With the benefit of hindsight, I wish I'd just done one at a time, but it's working. Does anyone know if the presence...

    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...

    Review: Dahua SD5A425XA-HNR 4MP 25x Starlight IR PTZ

    I want to reinforce the point made by @wittaj that the line likely needs to be even taller/higher/closer to the street than you drew in your second iteration. I encourage you to you look at an image of someone (even yourself) simply standing on your sidewalk, I think it will be obvious why you...

    Need Help tweaking HFW5231E-Z12 for night @ 240ft

    I am definitely guilty of that. I absolutely wasted time based on assumptions that these camera's concepts perfectly mirrored what I knew from photography. The iris setting may in fact control a physical aperture for a bit, but I suspect at some point the higher setting is adjusting voltage or...

    Need Help tweaking HFW5231E-Z12 for night @ 240ft

    Be careful with this suggestion. I'm an old school still photography person and went down this same thought process (opening the iris all the way for max light) but my testing of high iris values with this camera resulted in what appears to be "motion blur", even though the shutter speed was...

    Review: Dahua SD5A425XA-HNR 4MP 25x Starlight IR PTZ

    @Wildcat_1 is generally always super generous with his time, but let me offer a suggestion to @CastleSurveillance . . . Others members of these forums can try to help if you post more details. If you only want a live debugging session with someone, that's far more difficult for most people (&...

    Review: Dahua SD5A425XA-HNR 4MP 25x Starlight IR PTZ

    Your PoE switch should be sufficient based on what you said, but as sebastiantombs suggests, a dedicated PoE injector would let you know for sure. Having said that, be sure to double-check your cabling and connectors since a long cable run (especially on thinner cable like cat5/5e) can degrade...

    Only because you mention Intel specifically . . . earlier in this thread you referenced the post (which I'll copy here) that they were FIRST going to use DirectML that would support more than just Intel (AMD is the one of particular interest to me). Do you know if that is already done and...

    DeepStack LPR Custom Model

    I have labeled 120 images to be either DayPlate or NightPlate, most all of which are from the IPC-T5442T-ZE camera with the sample image above, most of which are from California license plates. I specifically chose images that all failed to be recognized by the current license_plate model. I...

    IP Cam Talk Custom Community DeepStack Model

    Regarding the motion detection from one zone to another, I use Dahua cameras and have found that it's "IVS" line crossing is FAR more accurate and sensitive, so I use that as event triggers when I want that functionality. The BlueIris alert shows the trigger as "External" (rather than a zone)...

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

    Let's see if I can get this math roughly correct. I believe 1 mile per hour = 1.46667 feet per second = 17.6 inches per second Using that info, and assume a vehicle moving even 30 miles per hour, that's 528 inches in one second. A shutter speed of 1/2000th would capture up to roughly a quarter...

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

    Ah, that's a great observation! Fortunately I run mostly Ubiquiti Unifi equipment so I was able to just take a look. My PoE switch for the camera is only about 60 feet away, and it shows the camera using up to 10.13W of power right now with the LEDs full blast, and I'm not using even half of the...

    DeepStack LPR Custom Model

    I agree with both @bigredfish and @biggen. @biggen in fact your posting on the Axton is one of the things that moved me to buy the illuminator on AliExpress, wanting to first try something less expensive. Thank you for that post. I do recognize that everything I'm doing/trying is "at the...

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

    I am up for testing anything, but I don't think I have a network issue simply because a network problem would cause packet loss or a broken video stream, rather than "corruption" or blurring in only a selective part of my image, particularly during the day when the rest of the image isn't just...

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

    I'm currently using iris=30. I was originally using 70-80, thinking that I was only allowing "in" more light. I don't know how Dahua manages the "iris", or if there even is a physical iris. It would seem there should be, so pure speculation on my part is that the physical iris operates with...
