TFTPD64 : an opensource IPv6 ready TFTP server/service for windows : TFTP server (pjo2.github.io)

Hi, I had camera and laptop connected to the POE switch. Laptop has 2 IP addresses configured on the NIC: 192.168.254.254 subnet mask 255.255.0.0 192.168.1.1 subnet mask 255.255.0.0 Here's the beginning of the camera upgrade log: U-Boot 2010.06-svn4911 (May 25 2018 - 10:24:57) I2C: ready...

I assigned 2 IP addresses to the laptop that was used as an tftp server. Described in Option 2 in the following post: https://ipcamtalk.com/threads/dahua-ipc-easy-unbricking-recovery-over-tftp.17189/

file is attached.

Yes, I used TFTP over serial on one camera, and then configured upgrade_info file, and upgraded few others over LAN. I used PoE switch.

Yes, via TFTP. After peeling off the cover (there's no adhesive in the corner to simplify removal), remove 4 screws, remove PIR/lens assembly.

I upgraded LNB8105X to DH_IPC-HX2X3X-Rhea_MultiLang_NP_Stream2_V2.800.0000016.0.R.200605.bin via TFTP, and then was able to upgrade via GUI to DH_IPC-HX2X3X-Rhea_MultiLang_NP_Stream2_V2.800.0000018.0.R.210707.bin. I did it recently, so not sure how reliable it will be. After upgrade IVS became...

I started with DH_NVR4XXX-4KS2_EngFrnSpn_V3.215.0000000.0.R.170807.bin via UART method. Then upgraded via GUI to later versions.

There was no connector on the board, just holes in the PCB. IVS features do exist in the interface, but I have no IVS-capable camera to test them with. Not sure about usb to serial (DB-9). No, nothing unique. UART from ebay.

I did not use Speco app. I installed Dahus gDMSS Plus on my phone, which works fine. I am now running NVR firmware V3.216.0000003.0, Build Date: 2019-05-21. Unfortunately I do not have a camera that supports IVS, so cannot say how it works. But I would expect it would support it. I see no...

Hi, If you plug USB drive and reboot your N8NXP it will tell you in the logs: “ProductName: NVR42XX_8P_4KS2”. I was not able to upgrade it with Dahua firmware via USB. Had to resort to upgrading via UART module. Success there.
