Hi

I don't know if this cam even supports usb output.
I'm not familiar with it, but afaik it's only a IP cam - and it only works with the xiaomi app and cloud services.

You could flash a mod firmware to make it "OctoPrint ready" if you want.

Hello and thank you for your reply.
So there might not be a solution to my camera?
How can i flash the firmware of the camera?
Otherwise I have a GoPro hero 5 session will it work with this?

A little guide for you

# Introduction and requirements
<img src="/doc/SXJ02ZM/img/xiaomi_mijia_2018.jpg" width="300">

The Xiaomi Mijia 1080p v3 model is the snow-white model that was released in 2018, and has an Ingenic T20L SOC with 64MB of RAM.
Unfortunately there is no known firmware exploit that allows us to easily edit the firmware to get ssh access to the camera.
In order to install OpenFang on the camera, we need to program a custom bootloader for the camera using a ch341a programmer.



## Requirements
You will need:
- USB CH341A programmer ([amazon link](https://www.amazon.de/Programmer-CH341A-Burner-EEPROM-Writer/dp/B01D4CXYJE)) and Programmer Testing Clip for SOP8 packages ([amazon link](https://www.amazon.de/dp/B07GLB1M75/ref=cm_sw_r_tw_dp_U_x_aQdKCbTGZ0032))
<img src="/doc/SXJ02ZM/img/c341a_clamp.jpg" width="400">

- Soldering iron (any below 15w; you should avoid warming to much the SMD components)
- Solder Flux (any rosin flux)
- Phillips Screwdrivers (size PH00, or PH0)
- a piece of plastic foil (e.g. kapton tape) to isolate the vcc pin when programming the chip

I know GoPros even less. I would google if it got a usb webcam mode or can stream mjpeg via wifi.

Well I can try although the price maybe better to switch directly to PiCamera... too bad because Mi webcam has night sensor... let's see if we find something on Gopro maybe I can use that one
Thanks again
