What is the best way to download a clip from my cam? can i just take out my sd card? or is it better to do it from the app?
You cannot download from the SD card using the app, per se. Using the app, you have to play back the video, hit the record button, and record the segment in real time.
If you want to capture a bunch of video, you need to remove the card and transfer it on a computer.
There is a feature request being tracked to allow direct downloading via the app. I’ve added your request for this to Wyze’s feature request tracker.
