Or buying cheap, no-brand or upstart brand cameras with cloud capabilities.
I had a heck of a time finding a proper POE recording DVR camera system for my mom's house without online or cloud bullshit, but still I isolated it on the network to not take any chances of UPnP port opening or dial-home crap.
The only system I would trust would be one that laid out their security model, source to their apps, and had a self-hosted server DVR option. The captological signals of 99.9% of security system websites do not instill confidence in my mind.
I have 30 POE IP cameras connected to BlueIris (Running on a server). It records based on activity, and is entirely local (including being on a dedicated VLAN).
The cameras are a wide variety of IP POE cameras which is helpful as I am not stuck to a single brand.
