Regular IP cameras don’t require a sub and let you store everything locally (even to the point of a micro SD in the camera for backup).
Ubiquity cameras are ridiculously over priced for their quality. They charge $140 for a worse camera (image quality/ features) than a $40 ip camera that supports ONVIF so works with open source Linux NVR software.
That’s why I said don’t trust it and block them at your router.
As long as you block them at your router Hikvision and Dahau are much better than the other brands at the same price. I’ve tried 6 different brands. I’ve been slowly moving them to all Hikvision.
