I don’t speak for Wyze or their design decisions, but I would guess that they’re trying to maximize the power reserve to minimize customer frustration. I’ve gotten fairly aggressive with the settings (maxing out the Detection Range, Motion Sensitivity, and Maximum Video Length with No Cooldown, Spotlight Brightness High, and recording to microSD) and have seen the battery drop on a stretch of cold, overcast days, so it can happen even with the currently available options. Last night I was even seeing the spotlight turn on when the Cam was supposed to be off, which makes me think it’s still got some glitches to be worked out, because unexpected things like that will eat some power. The little solar panel is impressive with it’s ability to keep this thing going, though.
Even though I wouldn’t expect to be able to do continuous microSD recording while this thing is being powered by solar + battery, I still think that it should have a time lapse feature.
