I have a QNAP NAS device with a bunch of storage. PPoE gigabit switch. A few ReoLink hardwired cameras pointed at all the entrances to my house. My QNAP device has a free NVR app that detects the cameras on the network and saves the recordings to the NAS. It's pretty simple and I don't have to worry about shady cloud-based devices.
