FYI - WyzeCam / Neos SmartCam firmware upgrade - Thingino
I recently came across a new source of FOSS firmware to upgrade Ingenic SoC IP cameras e.g. all versions of the Wyze Cam range and the recently bricked Neos SmartCams along with many others.
I have easily flashed both WyzeCam 2 and Neos SmartCams without any ill effect, and they have been happily working now for a month or so with SecuritySpy.
Unlike the manufactures original firmware there are no connections from the new firmware to sites on the internet, the firmware has a very usable web GUI to configure its many options. Thingino has numerous very useful features e.g. out of the box it supports the correct type of USB to ethernet dongles. The project appears to be under very active development and there is a Discord channel were you can get help from the devs.
I have no connection to the project other than being a satisfied user.

Hope this is useful.
