@brettcannon This is the one we bought, very basic, runs over local RF: https://www.amazon.com/gp/aw/d/B00ECHYTBI
We broke one after about two years and bought a new one, which we just gave away to family members (ones we like) recently.
As far as I know you can't use it to record video or audio. It has a talk button that is sometimes useful, but also sometimes used to freak out our older one.
Range was decent (though not compared to an internet-connected device). We could go outside when we lived in a townhouse in NY, and when we had a big suburban house it reached the whole thing plus the yards.
@pganssle @brettcannon i think we had one that was VTech branded, but current vtech models don’t look like it, and this one does, so perhaps it’s a white-label thing. Ours had some language on the box about an encrypted signal which i don’t see at a glance here, but yeah: just RF, not wifi
