Assuming you’re trying to flash a Cam v2, don’t extract. From your Mac, change the filename of the file located in the folder “_MACOSX” from “._demo_4.9.9.3006.bin” to “demo.bin”. Drag _MACOSX folder to the root of your SD card. Follow flash procedure “Flash Firmware for Wyze Cam v2 & Wyze Cam Pan” in instructions: How to flash your Wyze Cam firmware manually
@Antonius - Is this correct?
