The WyzeCam / Xiaomi Fang

The WyzeCam / Xiaomi Fang

The Xiaomi XiaoFang. Its a cheap IP camera (~$20-$30) that delivers decent quality. Is it a candidate to be 'improved' with a bit of hacking? You betcha!.

Spurred on by some external impetus, I acquired a WyzeCam. And of course, before turning it on, we took it apart!

A bit of squeezing, prying, and a small Philips screwdriver, and the contents were revealed. We can see the RX/TX/GND for the serial port, so lets assume its TTL and solder it up. I'm going to route the cables externally, so I hot-glue a header to the side of the USB-A connector and reach for the dremmel to expand the hole a little bit.

Inside, we have two PCB (the CPU etc board, and the camera board) connected by a pair of ribbon cables. Tweeze them out, and we are left with the individuals ready for the solder.

OK, reassemble, you can't even tell the mod is there, the headers just peak through the case above the USB port.

Hacking it is embarrassingly simple. Place a SD card in, and it sells you its looking for a script to run. Or, you can just modify files in /etc since its jffs2 mounted overtop of the rootfs. OK, well that was simple.

Now. I'm not super interested in the embedded app, so we apply fang-hacks. These are very basic, and zero security (not even a thin patina of guessable password), so we'll have to address that in a bit. The fang-hacks revectors the snx_rtsp_server to send a single stream locally. So i guess that's better. But I really would prefer this have multiple streams, save to the NAS when there is motion, and have a snapshot interface for home-assistant. So, naively, I assume there will be a great OSS project that has something, perhaps from the Raspberry Pi folks. Something w/a simple web interface, and exposing the uvc video endpoints (the hardware does support multiple simultaneously). Sadly, this was not to be, closest i can find is mjpg-streamer which is somewhat out of date.

So, I'll dive in and create a cross-compilation environment, get libjpeg going etc, and see where this ends up. If you know of anything (I mean anything) as an OSS project that would handle a HTTP snapshot interface, an RTSP streaming interface, and a simple web UI, let me know (maybe I'll see if vlc can fit?)

PS, the default method of config for this device is a 'novel' concept. You press a button on the bottom, it says something in Chinese, you run the Mi home app, it then gives you a QR code, you hold that in front of the camera, and it reads it. Um, novel, but not that convenient for me. So I think putting the initial password/wifi info on the sdcard will be the way I go. Or, maybe, pressing the button starts a WiFi AP for the next minute and connect via web interface.

    ps
    https://code.videolan.org/open-source/vlc-android/commit/22f2aa7ea7345c2b475a80cc7f00e50a021e424a
    “build: remove armv5/6 support”

    suggests I won’t be trying VLC 🙁

    Can I call Dan “external impetus” now? How about “The Imp” for short?

  3. db Julez says:

    Probably too soon but any word of an updated kernel hack to move this and the wyzcam away from being accessible to something else besides wyze online? Good little cam for $20.00 but hate the dependencies.

    • db db says:

      i compiled the kernel, it works generally but there is some issue w/ the video device driver. I parked it for now.
