If you want a really simple and cheap local storage camera, check out Wyze[0]. By "simple" I mean actually simple for non-techies. It’s one of the very few consumer oriented options with support for local SD storage. By default it uploads short clips of motion to “the cloud” and requires an app + wifi for setup, but you can disable clip uploading after it’s setup. If you don’t trust it even with cloud uploading disabled, you can just deprive it of internet access once it’s setup. (Block the device on your network, etc). It’ll keep writing video to the SD card while offline. Though with the fully offline approach you'll need to physically take out the SD card to access the video instead of using their app. There's certainly better local storage options out there. But for local storage with a single camera it’s the easiest and cheapest setup I know. [0] https://www.wyze.com/products/wyze-cam https://www.wyze.com/products/wyze-cam
