Playing with new firmware versions on my dahua VTH5241DW-S1, I flashed once again the wrong image => device bricked. Off course I'm aware of UART / TFTP methods for unbricking. This time I made the mistake, flashing a obviously too old bootloader which does not support the flash from this board...

Hi! Can you pls. post a link to the latest firmware files for gen1 vdp devices (VTO2000A, VTH1550/1560,...). I noticed that they were produced end of july and should have the fix for the authentication issue: General_VTOXXX_Eng_P_16M_SIP_V4.300.0000002.0.R.20210722.zip...

Just found the reason why dahua produced so many new firmware's in mid of july: Seems to be related to CVE-2021-33044 and CVE-2021-33045 (Dahua-Authentication-Bypass). So I warmly recommend to upgrade all devices, if they are placed in exposed areas.

I always wanted a script that notifies me of any event of my VTO2000A (doorbell ringing, faults, video motion, etc.). With such a script I could send notifications to my mobile phone, send emails,... With the help of some other users we realized this idea in PHP: The DahuaEventHandler So far...

Got a new V380 mini wifi cam and set it up to be recorded by my NAS (rtsp->surveillance station). Unfortunately the ID and the actual time are displayed in the cam's pic permanently. Any idea on how I could remove that? There is no option in the mobile phone app that was used for setting up the...

I'm running some VTO2000A devices. For some specific hacks I modified the "DeviceConfig.backup" file (actually just a simple xml file) and uploaded it to the device again. This was working fine until Dahua started to sign it's new firmware files (>2017). Now the config backup is much bigger but...

Found a new SIP firmware with english sounds for the VTO2000A. Some major changes were made, so they call it V4 now (General_VTOXXX_Eng_P_16M_SIP_V4.000.0000000.1.R.20180606). You can download it from here:Коментарии и оценки I installed it without any problems using VDPconfig from the toolbox...

Hi! Im currently analyzing Dahua's RS485 protocol that is used to interconnect VTO/VTH's and expansions. My goal is, to add a fingerprint from Dahua's security products (ASR1102A) and maybe other stuff. Is there any dahua RS485 protocol (DH-SD?) description available?

I'm running a VTO2000A at my house' door with SIP firmware. Now I want to add a fingerprint sensor. The official VTO2000-F cannot be integrated anymore, so I found Dahua' ASR1102A that would fit better. Looking at the manuals it seems pretty similar to the VTO2000-F, just power and a RS485 bus...

Hi! I recently installed a VTO2000A at my house' door runnning a modified version of the latest SIP firmware (General_Overseas_VTOXXX_Eng_P_16M_SIP_V1.000.00.0.R.20170425.bin). I hooked up the device in my astersik server (11.13.1~dfsg-2+deb8u5) and I am able to make SIP video calls from and to...
