If your camera has a micro SD card installed, you can set the cameras to record continuous OR only when they detect motion. Those are your only two options. I have all of mine recording to micro SD cards and set to motion detection. Wyze says they only support up to a 32GB card, but I have a 64GB card in all of mine and they work perfectly. I’ve switched to SD recording because it looks almost as good as HD quality. With the 64GB card, recording in SD quality and motion detection, I can get almost two weeks of video playback. That’s sufficient for me and I’d guess is sufficient for most people.
