Wyze Cam Outdoor, no wifi, NO WORK!

I was hoping I could hook up my wise cam outdoor to my RV and use it outside at night to see if any animals are entering my camping site. I mostly free camp, Boondocking, where I have no Internet access, thus no Wi-Fi.
I have an SD card in both the camera and the base station.
It looks like the new motion sensing capability will still only work if you’re connected through the base station to a Wi-Fi router, bummer.

Am I correct on this assumption?

Have you tried travel mode?
