One of the annoyances I find with a lot of cameras on the market is 1. most want a live internet connection, and 2. most only offer cloud storage.
It can take a while to find one that has local storage, and can operate without connecting to the Internet.
Is a problem with smart devices in general, they advertised as WIFI which is misleading as they are usually internet devices, with WIFI just the means of connecting to the internet.
For localised ones its best to look for bluetooth or ones that come with a hub, they both usually more expensive than the WIFI/internet one's.
My camera is a cloud (WIFI) camera, but I am able to use an SD card in it. Although the app tries to push the cloud storage on to me.
