Mini 1080p wifi camera from Aliexpress, how to use without app (FtyCamPro)?

Wuppiduppi 61167 202
Best answers

How can I use this AliExpress mini Wi‑Fi camera without the FtyCamPro app?

Open the case, identify the chip, and replace the vendor firmware with an open build; for TXW817-810 cameras the thread settled on OpenTXW81X, flashed with a C-SKY/CK-Link style programmer via an STM32F103 “blue pill,” after first making a backup of the original flash. [#20946151] [#20946175] [#20946214] After flashing, the camera creates its own AP (typically 192.168.4.1); connect to it in the browser, set your Wi‑Fi settings, and start the stream with `startdriver TXWCAM`. [#21645812] [#21645938] The live feed is then available as RTSP at `rtsp://{ip}:7070/webcam`, and at least one user confirmed the camera sensor worked with the open firmware. [#21695014] [#21645946] If your board turns out to be the BK7252UQN48 variant instead, there is a separate open firmware project for that chip. [#20946175] [#20946214]

    Current progress:
    Managed to create a makefile and generate a booting binary.
    Next step - OBK.

    One problem i don't know how to solve. .exe execution. I use WSL - so exe more or less work.

    No log currently, probably due to semaphore return value.

    Nice, what is the exe used for? Some packaging tool?

    Well, most of our workflows run on ubuntu, but Windows simulator build works on windows-latest, maybe that's what we need to target here..

    Test build.
    Camera doesn't work for me (not in AP mode, not in STA).
    No GPIO, or any other periph.
    No LFS.
    Config/flashvars is stored via EF.
    Reboot doesn't work (mcu_reset does nothing).
    Watchdog doesn't work (or perhaps it does, but look at the problem higher).
    Mutex significantly slows log down.
    MQTT is there, but not tested.

    Have you tried the rtsp webfile yet? Would be nice to be able to open the cam in a browser instead.

    Not really sure if that's how it works but would this setup work maybe?

    I would assume you also need to change this to match the web path. But if that doesn't work hopefully someone figures it out soon.
    You have already made so much progress though it's amazing. I can't wait to start tinkering with mine soon.

    matching those doesn't seem to help. probably missing something obvious :(

    the ultimate of course would be rtsp and OBK support with http window stream option in GUI :D

    a basic non-OBK stable RTSP/http opensource replacement for the dodgy p2p cloud stuff would be OK too

    I've been looking through the files for a while now and noticed that most of the defines in spook_config.h have no references for them anywhere apart from these 3:
    Code: text Expand Select all Copy to clipboard
    #define SPOOK_PORT				7070
#define MAX_DATA_PACKET_SIZE	1440
#define SPOOK_CACHE_BUF_LEN			1600

    It also seems like webfile uses the AVI file format and requires an SD card to function. However even if you got it to work it still uses RTSP so won't help with opening the stream on a browser.

    Added after 21 [minutes]:

    Actually it looks like handling HTTP requests (at least for video) hasn't even been implemented.

    The most basic HTTP preview should be easy to do. Just create endpoint that return JPG image and implement it, then call it repeatedly in JS.

    Accidentally deleted it, but new build is here.
    https://github.com/NonPIayerCharacter/OpenBK7231T_App/actions/runs/17322792613
    LFS added (44kb).
    Camera init is now in separate driver.
    startdriver TXWCAM [buf_size]
    buf_size defaults to 60000.
    Additional command - CAM_Show_Timestamp - shows ntp timestamp. 1 to enable, 0 to disable.
    Driver can't be stopped, since there are no deinit functions in SDK.

    It's not just jpg that must be stopped.
    There is csi_open but not csi_close
    There is spook_init but no deinit.

    It doesn't really matter though. Why would camera needs to be deinited? Just reboot if really needed.

Topic summary

✨ A mini 1080p WiFi camera from Aliexpress priced under 3€ uses a Beken BK7252UQN48 AU3437XB chip and requires the proprietary "FtyCamPro" app for operation. The device creates its own WiFi network and assigns an IPv4 address but shows no open ports on scanning. Opening the case reveals the Beken chip, and firmware resources for this chip are available on GitHub (beken7252-opencam), enabling potential firmware backup and custom flashing after identifying the flashing pins. Some similar cameras use the Taixin TXW817 chipset, which has a different ecosystem including SDKs and programming tools like TXProgrammer and CK-Link debuggers. Attempts to access internal flash memory via QSPI/SPI have been made, but require delicate soldering and specialized hardware. The Taixin TXW81x IoT SDK and C-SKY Development Kit (CDK) support firmware development and compilation. TXProgrammer can be configured to English for easier use. A 2MB flash dump from a TXW817-810 based camera has been obtained, and a demo application runs on this hardware using hgSDK. Overall, the discussion covers hardware identification, firmware extraction, SDK availability, and programming tool usage to bypass the official app and enable local control of these low-cost WiFi cameras.
