Wyze is quite a bit different, as you dont even have to use the cloud for them. Even their security system has the ability to use SD cards for storage of video and events though you lose the whole offsite backup aspect and now with the new intruder protection aspect, you lose the ability for them to flag intruders even before they access your house.

They have had 3 CVEs that I know of recently, and all have been patched as they patch their firmware SUPER quick (almost too quick, i have had firmware patches hit days after I applied one). So they seem to take the whole security aspect somewhat seriously and are willing to patch constantly and continue to update firmware even on older products.

That said I purposely am not using their inside cameras and only their outdoor ones. I dont honestly care what people see of me outside the house because its nothing my neighbors dont already see anyway, I DO care if people see what is going on with my kids and my family inside the house though.

Wyze was worse unfortunately. Last time I checked they just EOL'd their cam that had security holes

I've been meaning to give this a try.

So far as I'm aware with that software "installed" on the camera (which can be removed simply by removing the SD card) you should be able to set up the camera's with standard local access and block them from the internet entirely.

Its a thing I plan on trying out in the near future, but it works like it should then its like a $45 (CAD) wireless(ish) security camera. Which isn't bad.
