That was the one I used - I went here (DahuaWiki), and filtered to find the closest model by specs - I don’t see the model you list there at all though, so not sure... iirc, when looking through the files before though, several of the similar spec cameras used the same firmware file, and in...

@phenry370 - yes, I was able to do it, following the instructions here (Dahua IPC EASY unbricking / recovery over TFTP) - I ended up taking the cameras down and wiring them to a switch temporarily, as my network setup is somewhat complex, however once I did that, I was able to flash them. I...

I am not sure I am following you - at the top you say "no change", but then you say below that "that error does not show up" - I thought your main issue was the 'MSVCR120.dll was not found' error - have you gotten past that?

You have to install a MS redistributable package - see below for help (note that I ran into this too, and had to install one of the packages this takes you to - the first one didn’t have what I needed, so I tried the others until it worked, (sorry - forget ehich one now...))...

@alastairstevenson - OK - we are making progress! Thank you for the help so far! I got some time so hooked the camera to a switch with nothing but the BlueIris PC on it, and configged as per the instructions at the start of this - first time through it hung on one of the IMG files, but then I...

Thank you, I will give that a try and I also plan on trying it direct to the computer instead of through a couple switches as it is set up right now… Do you know if that “install“ file is required or is that optional?

I changed the .ini file to allow write to everything, but same result.. :( But - in looking at your link in your sig, I found someone who ran into issues in a multi-nic machine, and my laptop has a dock, so has 3 nics - 2 wired & 1 wireless. I disabled the 2nd wired & the wireless & tried...

how do I check that? From a Windows FS perspective, they are RW to my account - is that different since the TFTP app is presenting Root up as some sort of share?

note that my "install" file is 0 bytes, and that is what threw the error in 7-zip - I went to a different firmware file from Dahua, and that file there seemed to have the order of install - here is the contents from the different FW version (so assuming it won't work for me, but wanted to see...

That file is there, I think... Path to this dir: C:\dahua\Dahua_TFTPBackup\root

Hi all - I have the Lorex LNB8921, which seems to map to the Dahua N84CB34, and want to update it to the Dahua FW. I have been through the instructions on this site and several of the mods to the commands.txt file, but am stuck. I see the camera boot ok, and it seems to want to start the FW...

Thanks, @mat200 - That is the camera I am trying to upgrade - I went via the web login & tried to upload the firmware from DahuaWiki, but while it didn't throw an error, it didn't seem to do anything, either... Any tips, tricks or thoughts on if this might work? Thank you!

this seems closest to the Lorex in terms of looks/specs: DahuaWiki

Hi all - as said above - I have 4 of these cameras, and just made the jump to BI and one of the 4MP turret cams from the store here, but wanting to get some of the Dahua goodness on these other cameras (i.e. plugin-less viewing via a web browser) - is that possible, and any ideas which Dahua...

OK, @looney2ns... you have convinced me - I ordered a newer desktop (refurb, per the link you provided), and will give BI another try - I own BI already anyway, so will be an inexpensive thing to try out... :) Thank you all for the help/guidance/ideas!

I am comparing these two cameras: https://www.amazon.com/EmpireTech-IPC-T5442T-ZE-Vari-Focal-Eyeball-Starlight/dp/B08C77TNY9 and https://www.amazon.com/Loryta-IPC-T2831T-ZS-S2-Starlight-Vari-Focal/dp/B087BVQDK3 The top one is 4MP with 1/1.8 sensor, bottom one is 8MP with 1/2.8 sensor. Use...

Thank you, Steve! If the lorex cameras do work with a dahua NvR, is there a particular one that is good? I don’t really need a 16 camera unit for my setup, And I thought the second drive was mainly for fail over and I can tolerate loss of drive and or footage. Is that correct, or does that...

I currently have a Lorex N841A82 NVR (from Amazon), and 5 8MP cameras. I don't like the NVR, and would like to replace it. I previously tried Blue Iris (BI), but it killed my server-class machine (weak on graphics), so would like to avoid that route if possible. What I don't like about the...

I also have this issue with TC on a Shield. I had TC working with 5 cameras (not Wyze), and tried to add the Wyze to it, but kept getting 2FA prompts, even though from the get-go I did not have 2FA turned on in my Wyze acct. I tried getting support in the Wyze forum, but did not get it...
