    Dahua config backup encrypted?

    I am able to do this. Config is firstly gzipped and then crypted using AES. Key is type of camera. IPC for still cams and SD for PTZ. Rest is padded with zeros.

    New Dahua cams are not HiSilicon based, watch out!

    More info: 1. TFTP reset procedure is IN KERNEL at Kernel boot - if you flash and something goes wrong with kernel - you have a dead camera. 2. No console, crippled Dahua Bootloader without antyhing more than booting image. 3. All is secured by RSA 4. Software looks a little bad according to...

    New Dahua cams are not HiSilicon based, watch out!

    kobebeef - do You even know what you're writing? Recovery via TFT is not possible via upgrade_info.txt file because all functionality is removed because of limitation of size in IPL in Uboot payload.

    New Dahua cams are not HiSilicon based, watch out!

    DId you even see software or you just write? Uboot even doesnt have command line, it just boots kernel which is checked accross RSA key.

    New Dahua cams are not HiSilicon based, watch out!

    The quality of software is a pin. Bootloader i.e. is a BLOB with crippled Uboot (which is embedded as compressed xz stream inside...) just to boot kernel. There a lot of registers and it looks like a huge "try and merge" old code (sonia and rest) with different platform. Many of things is...

    Firmware for newer dahua cams as well as detailed specs available here

    This problem exists since 2017. It is very visible in slow paning. I had to patch it remove the problem as Dahua dont gives a s..... Also upgrading will not give a way back as secuity level is incresed from 1.4 to 2.0 and firmware is encrypted.

    New Dahua cams are not HiSilicon based, watch out!

    Just wanted to let you know that new series of cameras that Dahua are selling are not HiSilicon based. They use SigmaStar/Mstar CPU/DPSs with NN (SSC339G).

    Dahua config backup encrypted?

    Due the fact, there is a script available that allows reading and even modifying the internal config of dahua devices (Dahua-DHIP-JSON-Debug-Console) this issue seems to be obsolete now. Try to modify PTZ speed level ratios via this method :) Good luck...

    Dahua Firmware Mod Kit + Modded Dahua Firmware

    watchful_ip, I patched all of this and made a uncrippled firmware for 59225 PTZ cam. But new series like 5442 has secureboot fuse burnt and even that i cracked all of this - there is no way to load it into camera. Now i have a good paper brick :)
