Re-organized the forum to more cleanly delineate the development section, as the end user support side appears to have taken a life of its own!

Thanks for highlighting this.
Can you please guide me how to verify this on my own camera.

Arreglado el enlace en los dos post!6IIFgb5Z!4ZU9rFOBlmUP6yX0dVyxil7I4QXp-B9WG26V9N6AreM

Este es el nuevo enlace, espero que funcione

Por favor carcamonia . Podría volver a poner el archivo. Lo bajé y actualicé mis cámaras pero me faltó una y ahora no encuentro el archivo. El link de mega dejó de exisitir. Gracias.
Hacking & Modding / New life to Unitoptek PTZ Dome Camera with HI3516C chip
« Last post by sukkis on January 22, 2018, 07:20:37 am »

As many other here, I also bricked my camera by flashing wrong firmware. Is there any method to unbrick the camera? Wifi seems working but it losts camera's id, so now it's called just IPCAM- instead of IPCAM-1234D

Camera I bought is this below

I'm thinking to buy serial console Recovery cable from ebay and try to connect to pins with it. Pins I think are in right top corner in photo below

Or is there any chip for ptz camera I could buy and replace that original one? No luck after finding for same motherboard.

And yes, I realize I can double or triple my budget and get a better NVR. I might just do that. But first I wanted to understand what the minimum viable setup looks like.

The sucky part about the things is the monolithic package containing the recorder and webserver components (It's Sophia for XiongMai-sourced stuff.) One of the first tasks is to pick it apart, see what the component programs are (it's effectively a distro inside a distro) and what they do.

These systems have wildly different functionality inside and outside China, if you read chinese you'll see there's a lot of things like automatic upload to central authority sites and similar stuff that isn't there in non-chinese mode. It could be that the binary is packed up tightly so that people can't see the level of snooping that goes on.

The actual Chipset linux distro itself is easily buildable from the SDK as mentioned.

What would be AWESOME would be to port zoneminder to these devices. If you check out the zoneminder website you'll understand why.

Firmware / XiongMai-based DVRs - Sophia?
« Last post by Stoatwblr on January 19, 2018, 10:42:38 am »

Has anyone managed to unpick the monolithic Sophia binary to work out what its components are?

This is the one that contains the swiss-cheese uc-httpd server along with DVR functionality.

I can see various GPL symbols in it, so I'm regarding it as fair game for examination.

Has anyone managed to get XiongMai or anyone selling devices it uses to comply with GPL?

I know this thread is a bit old but it seemed to be a relevant starting point.  I've read through the forums for a while now, but still don't get the answer to what's probably a pretty noob question.

Why hasn't anyone tried to define a standard spec that would allow cross camera firmware to be written?

Yes, I have some idea of the nightmare variations of hardware out there. But the thing is, this problem has been around in a lot of areas, and usually a specification is defined to allow HALs (hardware abstraction layers).  The idea being, if a manufacturer opted in, they would be compatible only by having to maintain a thin abstraction layer, on top of which higher level firmware abstractions were built.

A real life example of this is Android phones. Ever notice how lots of Android phones get slow updates or none at all?  It was partially due to a similar problem of many different hardware designs.

So now to try and address this, Google is investing in something called project treble, to make HALs more consistent, well defined, easier to maintain.  One quote about it: 

"To solve the hardware abstraction layer issue, Android O formalized the division between hardware sub systems like audio or camera, and their clients on the software side. These new formal divisions specify the interface between a HAL and its users. There are now around 60 formal interfaces for various hardware components, known as HIDLs. The goal of a HIDL is to allow the framework to be replaced without having to rebuild HALs. HALs will be built by vendors or SoC makers and put in a vendor partition on the device, enabling the framework to exist in its own partition..."

So the noob question is, why couldn't at least a basic HAL be spec'd out to allow cross camera firmware?

Is the only issue getting a company to build a camera that supports the spec?

Could a kickstarter gain enough traction to allow one to be built with the pitch being, the worlds first truly open IP camera?  It would seem like if just the one camera got enough orders, it would catch the attention of other manufacturers, maybe add some pressure to collaborate on some standards.

Ok I'm ready to know how crazy all this thinking is, if anyone doesn't mind helping me to understand.


Hacking & Modding / Re: GRAIN 8135S CPU SDK
« Last post by camboy on January 02, 2018, 03:36:29 am »
Hello folks,

Any progress with this cam ;-)? This is the only place I could find anything about the YooSee cam. It's a Techage 1080p and their web site actually contains some firmware files; I've tried this one:

After unpacking, the .bin file can bin uncompressed with 7z unpacker. There are then a few .sqsh4 files, which are mountable with the squashed filesystem type under Linux. Then one can find the scripts under etc/rc.local and a few commands for flashing the FW.

I've opened the box; be careful not to break the clumsy camera cable socket lock (happened to me of course). There are a few anonymous chips but the most important is:
- CPU: ARM Grain 8135S
- WiFi: Realtek 8188 FIV
- Eth: IC IP101GR
- Serial Programmer: 24C08E 735D2

To be able to brute force flash it, one probably needs to go through the 24C08E:

I didn't figure out so far how to communicate with it; it seems to be "write-only" (?) reading the docs.

I didn't plan to reverse this but the stupid thing has NO open ports but the dummy RTSP (which sends nothing of course) and the bloody thing sends all the audio/video stream straight after turning ON to the internet. Their CMS connects then there and reads the streams back to your LAN to see anything.
