    Review: IPC-LPR237B-IR / Equivalent of Dahua ITC237-PW6M-IRLZF1050-B - ANPR, Traffic & Access Control Camera

    On the topic of NVR integration, what does this support in terms of pro-active alerts of plate recognition events and are there filters for whether a plate is a "known friendly" plate versus a new one, etc.? I assume (but please confirm) email alerts probably exist, though that wouldn't be ideal...

    what is the network type = fast/slow setting?

    I started checking to see which other cameras have this toggle, and found that one of my Amcrest cameras (using Dahua firmware for those who don't already know that) also has that setting, showing it in a more user-friendly manner to make clear that it is a setting/toggle:

    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...

    SD59225U-HNI DH_SD-Eos_MultiLang_PN_Stream3_V2.810.0000000.4.R.200509.zip；

    @looney2ns You are obviously one of the most experienced people here at updating firmware, so knowing that you've done everything in the best manner possible, and that Dahua hasn't updated the firmware download on their site since the Aug 2018 version (SD59225U-HNI), I'm wondering if that...

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

    Wow. Someone is a bit sensitive. You say you, "could not check at the time", yet you still posted here on a thread with numerous posts about v16 potentially being dangerous. You could have waited to post on this forum until you could check, but you chose not to. I even apologized in advance if...

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

    Why do you say, "I think", rather than looking to see what you just installed? If you really got it from Dahua's website today, then I suspect you probably installed 13 (not 16). That's what I see on Dahua's website today, and is the version shown in the screenshot of Andy's post 5 messages...

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

    I'm catching up on this thread and the original post from Andy doesn't appear to have an attachment or link to the firmware mentioned here. His post immediately prior to this one included a Word doc with the download link, but I'm not seeing an attachment or link for this thread. Was it removed...

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

    I highly HIGHLY recommend you reboot your device before running the update. I've seen many failures in updating when I forgot to first reboot, and never get a failure (with good firmware) when updating after a simple reboot. If you have your cameras set to reboot daily, this may not be such a...

    Review - Dahua IPC-HFW7442H-Z 4MP Ultra AI Varifocal Bullet Camera

    @EMPIRETECANDY Is there another model like this, with the license plate recognition, that also has 12x or greater zoom like the IPC-HFW5231E-Z12E which I & others have purchased from you to do license plate recognition with external software? I’ve looked all over Dahua’s site and haven’t been...

    Dahua SD card overwrite not working

    I've been using the Samsung PRO Endurance 128GB in 6 cameras, recording 24x7 for just under a year with no problems. There were issues with the initial firmware but about 6-9 months ago the firmware updates solved everything for me. If you're current on Andy's firmware, then try one of the...

    Review - Dahua IPC-HFW7442H-Z 4MP Ultra AI Varifocal Bullet Camera

    @EMPIRETECANDY I don't see any mention of this supporting the "Enhanced PoE" (ePoE) either here or on your sales page, so I assume it's not supported. Are you aware of any other camera with ANPR that supports ePoE?

    Review - Dahua IPC-HFW7442H-Z 4MP Ultra AI Varifocal Bullet Camera

    Do you know/Can you tell me, without using an AI NVR, is it possible for the camera to alert an outside system (such as an HTTP GET or POST) to alert some other system to the LPR event? It wouldn't have to contain any data other than, "Hey, something happened" and then let the external system...

    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...

    DH_IPC-HX5X3X-Rhea_MultiLang_NP_Stream3_V2.800.0000005.0.R.190325.zip

    I also highly recommend a reboot shortly (or immediately) before updating firmware. I've never experienced a failure to update after rebooting, but have experienced many failures when I forgot to first reboot. Note that "failure" can take many forms. For example, several times the update process...

    Dahua HFW-1831E in-depth review

    No, a lower FPS will not help. If you cannot get a fast enough shutter speed to eliminate the ghosting or "motion blur", then changing FPS will simple give you more or fewer blurry images. You say you "understand it relates to light exposure", but then you ask whether FPS will change and then...

    SmartPSS zoom on playback timeline without a mouse scrollwheel

    @jack7 You're awesome! Thank you! I'm mad at myself for not thinking of the two-finger scroll, since that's (obviously, or should be obvious) the touchpad equivalent of the scroll wheel. I have a Thinkpad with that enabled and it worked perfectly. Thank you!

    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...

    SD Card Recommendations

    Consider paying a bit more for an "endurance" card, depending upon your situation. See my post in this other thread for my explanation.

    Dahua HFW-1831E in-depth review

    Ghosting has nothing to do with bitrate. Ghosting is really just blur which is a result of a slow shutter speed. The "ghost" image you're seeing is not the result of capturing fewer pixels (bitrate). It's because the object in motion has moved from one place to another faster than the shutter...

    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 still haven't figured this out, but I thought a video/screen recording of what I'm seeing might be useful to others if they encounter something similar. At this point I should probably rename this thread to be "SmartPSS doesn't list all events", but I'm not sure if/how I can do that. If it is...

    Dahuaddns.com is closed, looking for an alternative

    I've used dyndns.org (now hosted through Managed DNS DDNS DynDNS Services | Dyn) for at least 15 years, long before Oracle bought them. For more than a few hosts it's a paid service, but even then it's relatively inexpensive, always worked for me, and supported broadly by the market as a whole...

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

    I'm trying to use WireShark to get a clue for what's going on. I see a series of communication between SmartPSS and my cameras with the following json: { "id" : 209175, "method" : "mediaFileFind.findNextFile", "object" : 1938398168, "params" : { "count" : 32, "object" : 1938398168, "this" ...

    IVS event skipping frames on the local microSD recording

    Rather than create a new thread, I'm replying to this old one to ask if anyone is aware of any fixes to IVS missing the start of a recording? Has Dahua even acknowledged this problem? I do record 24x7 onto Samsung Endurance Pro cards but lose 1-2 seconds with every IVS event, which is ironic...

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

    I can't figure out why something as fundamental as searching for records to playback doesn't work reliably (but it doesn't), also thinking that more of the rest of you would be having the same problems. I've installed (multiple times) on two different Windows 10 computers, and both exhibit the...

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

    I may have spoken too soon. At least one of my cameras is not showing all events even when queried by what I thought was the "good" version listed above. For what it's worth, version V1.x of SmartPSS definitely works on all cameras. So I'll keep investigating, but I'm convinced something in...

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

    I finally discovered that there are multiple versions of SmartPSS that are both V2.002.0000007. Below are the two install file names that I encountered. Note that one has "FLIR" in the name with a "T" in the name and date 190122. That one does not work properly and is the one I was using when I...

    How to Replace Analog system into IP system easily

    That’s what I have & do today, with a PoE extender every 100M. My question is whether Dahua offered any EXTENDED PoE Extender that would let me use only one extender/adapter up to 800M (their ePoE standard).

    How to Replace Analog system into IP system easily

    I just install a IPC-HFW5231E-Z12E using the 2nd configuration in Andy's diagram above, using the simple LR1002 since the IPC-HFW5231E-Z12E is an ePoE device. It too was plug & play. It simply worked. @EMPIRETECANDY Does Dahua offer anything like these LR1002 adapters which allows an older, PoE...
