Well, since you’re posting here I’m assuming you’re also asking for the ones that are the most privacy respecting (since you don’t explicitly mention that in your post)?
Sadly, today, there are less than a few options if any for good privacy respecting home security systems and they are somewhat DIY too. No mainstream device is going to be privacy respecting.
I don’t own a home so I don’t have a definitive answer so hopefully someone else can help you out better. But I do recommend searching for what you’re looking for on YouTube and checking out what features and functionality different products offer that are privacy respecting.
Ideally, you’d want a local stream to your computer/phone and the footage not being sent to any company servers or cloud. You also don’t want it to have any “smart” features that connect to any AI. You also don’t want anything that requires a subscription for you to operate them as you’d keep paying to worsen your privacy.
And Ring camera’s are absolutely horrendous for your privacy, FYI.
