I recently encountered an issue with my Wyze Cam V3 regarding the SD card functionality. Despite having a properly formatted 16GB SD card installed, I faced problems when trying to playback recordings triggered by person detection. The camera consistently prompted me to insert an SD card, even though one was already installed. This issue was peculiar as my other cameras functioned without any problems. After reaching out to support without resolution, I decided to explore potential solutions. I discovered that updating the camera firmware and ensuring the SD card was correctly formatted resolved the issue. It was a frustrating experience, but troubleshooting and persistence paid off. If anyone else encounters similar problems, I recommend checking the firmware updates and SD card compatibility first.
