Since my first Wyze camera was a Cam Pan v3 (and I also have Cam OG and Cam v4, along with Video Doorbell v2), I don’t have experience with the “old” UI, which is what I think—based on what I’ve read in the Forum—Cam v3 and earlier models use, so I’ve gotten used to the “new” UI because it’s what all my Wyze cameras use. I understand from reading here that this is a polarizing topic, though, with some users preferring the older UI with the horizontal timeline scroll.
I’m not aware of any way to increase playback speed using the camera and app, though there’s a Wishlist item requesting that:
Probably the best way to view microSD card recordings at a higher speed is to pull the card from the camera and stick it in a PC—at least with Wyze cameras—but that’s not always practical. I’d really like to have the ability to access the local storage over my LAN and just pull the files directly off the card remotely. A non-Wyze camera that I use allows an in-app playback speed range from 1/16x to 16x.
