Adding a microSD Card to the IPC-HDW4433C-A, and dumping the firmware...

[Purduephotog]

Yes, it's a cheap, not - upgradeable chinese camera.

Anyway I dumped the firmware and discovered lots of little goodies in it. In addition, another thread references it as a IPC-HDW4431C-A-V3 ; which would imply it may be able to be upgraded using the Dahua Kit that was so nicely built here.

I'll be finding a spot to put the files, but there was this special line:

case "$product_name" in
    "IPC-HFW4431B" | "IPC-HDW4431C" | "IPC-HFW4431B-AS" | "IPC-HFW4431R-VF" | "IPC-HFW4431R-VFAS" | "IPC-HFW4431R-Z" | "IPC-HDBW4431R-VF" | "IPC-HDBW4431R-VFAS" | "IPC-HF4431" | \

    "IPC-HDBW4431R-VFAS-X1-27135" | "IPC-HDBW4431R-S-V3" | "IPC-HDBW4431R-AS-X-V3")
        product=IPC-HF4431B
        ;;
esac

The 4433 is renamed as the 4431C-a-v3, so it falls into the IPC-HF4431B (yay!).
That also means this line:
[m[0;32;32m00:00:04|[sdcard] Not Support SD Card !
[m[0;32;32m00:00:04|[sdcard] Not Support Wifi Card !
[m[0;32;32m00:00:04|[sdcard] Not Support SD & Wifi Card !

Came from:

So the hardware config says "No SD Card (true)". Find that, destroy that, and I might get my SD Card working

OK, that's enough for now I guess....

....and it was literally as easy as modding the hWID. Unfortunately, it still doesn't show up, but that's the next problem (assuming my soldering skills are still 'mad'....

Interestingly, the VSS pin wasn't connected. I jumpered 3.3V into it (still waiting on confirmation for a particular PNP transistor). Then I had clock issues. But more importantly:


[0m[32;40m05:05:26|[libStorage] [ver:] info tid:983 CStorageManager::dump():
[0m{
"BUS" : "MMC",
"Capacity" : 31914983424.0,
"LogicNo" : -1,
"Media" : "FLASH",
"Name" : "\/dev\/mmc0",
"Parent" : "",
"PhysicNo" : 0,
"State" : 0,
"Volume" : 0

So the firmware can see the card, but alas I had other issues. Rebooting did not resolve it and I haven't gotten it to pop back up yet. I'm not sure if that means I'm not pulling down the CS line correctly or what.

So if you have or get new cameras, teardowns are always appreciated.
