Config Tool Dahua NEW!

There are a variety of problems that I will try my best to explain and share the possible solutions. I have gotten pretty comfortable with these cameras and have purposely bricked them to various degrees of severity just to validate the recovery process. Most people "brick" their cameras trying to upgrade the firmware. This is not a serious issue and it can be corrected very easily. The camera runs an upgrade service on port 3800. The configTool always shows a default port of 37777 but this is not an issue as it can do the upgrade on port 3800 anyway. Change your port to 3800 and use a firmware file lsted below and you are back in business.

1A. If port 3800 is open you can connect with the Dahua Config tool (link below in tools). I tdefault to port 37777 but change it to 3800 as this port where the upgrade daemon is listening. Port 37777 is a redirect but it won't work if your firmware has failed.

Once you telnet into the camera, there are number of useful binaries in the user shell that can help correct and diagnose some of the problems people are experiencing. One of the helpful steps is to kill the /var/tmp/upgraded process and run it in the foreground so you can see what is going on and easily capture error messaged. The /var/tmp/upgraded process is what opens the port 3800 and allows you to connect to the camera with the config tool if your web services have failed. There is also another copy in usr/sbin/.

To stop the reboots you can update the flash. There is a parameter called appauto that tells the camera to auto start /us/bin/sonia. If you want the camera to start and not invoke the shell script that launches sonia, you need to set appauto to 0. This will stop the camera from rebooting when sonia is not running. This cam be accomplished by running '/sbin/appauto 0'. To turn it back on, just run /sbin/appauto 1. This writes the boot parameter in flash that the kernel reads before starting the process. You can check the current status of the appauto bootparameter with 'cat /proc/dahua/bootpara' It will only show what the parameter was when you booted up, so if you changes it you need to reboot to see the change in /proc/dahua/bootpara.

You can use the HTTP API to configure some parameters that are not yet in the web UI. For instance, another member discovered he could enable NFS through the web UI in addition to the local SD card. This config is not possible through the web interface as you need to pick one or the other.

These documents details the API of Dahua video products (links provided to some of the versions below). Programmers or users can access and configure Dahua video products through the API. Every setting of the camera is available through the API whereas only a small number are available through the WEB interface. The document with version 1.10 is available with firmware version 2.0 and above. This document with version 1.20, 1.21, 1.22, 1.23,1.24,1,25,1,26,1,27,1,28 is available with firmware 2.210 and above.This document with version 1. 29 ,1.30, 1.31, 1.32, 1.33, 1.34, 1.35,

Starting to document the U-Boot environment and the Serial interfaces on the various cameras. Using a USB to TLL interface,, you can connect to the cameras and use the TFTP process to load partition images files or upgrade.img to load firmware to the camera. You need only connect the TX, RX and GND connections to communicate with the serial interface. The serial config is 115200, 8, N, 1, N.

Is there any chance that using a Chinese version of the config tool would make a difference? I had some l luck a year ago when I purchased some Dahua cameras from Ali Express. Upgrading the Eng firmware seemed to brick my cameras, until I tried switching from the English config tool and using the Chinese version (the gui buttons were all in the same place). I'm not sure why, but the Chinese configtool solved my problems.

But then I tried this Chinese tool I have, basically the same as my other Config Tool, so I was able to guess at the Chinese buttons. It was able to connect to the camera, install the new firmware, and fixed the entire issue! Everything is back to normal for me, and my camera has the new firmware installed.

So I'm wondering, did I just get lucky, or do I have some magical Chinese tool that overrides regional settings or something-- that can help out other people who bricked with wrong firmware? What I used is called General_ConfigTool_Chn_V1.06.0.R.120628

If you forget the administrative password for your Dahua IP camera, there are multiple methods to reset it to the default password. These methods include using the Dahua DMSS reset tool, resetting the camera through the reset button, factory resetting the NVR, or using the Dahua IP Search Tool. By following these steps, you can regain access to your Dahua IP camera and protect your home or business.

In addition to searching for IP addresses, ConfigTool Mobile allows users to change IP addresses for the devices, configure video settings, control PTZ, modify network settings, and view system versions. The app also offers more tools for users to check P2P online status, order IP addresses, reset passwords, scan ports, view network information, and calculate storage capacity and bandwidth. ConfigTool Mobile is available in English and Vietnamese. Moreover, users can register as members to access more advanced features, such as saving account and password information, earning STAR points to perform device setup features, and more.

I was unable to make any changes to the NVR config that would survive a reboot. My admin credentials remained intact and usable, but there was little hope of fixing the issue via the NVR GUI. I attempted to navigate CLI via telnet, but was not able to correct the issue myself.

This tool works the majority of the time I have used it, but there are obviously failures you can expect. In such cases as described by Jon this tool may not work, but since it is so easy to try and surprisingly effective I felt compelled to share.

If I use the tool in the next days I will post my Log file so you can see what is going on. Otherwise, just wait to use the tool and read the results yourself. I just wish I had a successful log file on hand so I could answer your questions.

However, after using the tool and checking the log files, you can see the activity going on. I am sure some of the readers on this site can offer some more details after reviewing their own log files.

So, newb question. If you have a normal Linksys, Netgear router that has had its problem in the past with security. So if you leave the default user & pass on the router config & you have it set to not respond to icmp, telnet. Can it still be hit from the outside? 2351a5e196
