Yes you can, if you can afford a Ring+subscription you can afford to get NVR+4 cameras and install them. Reolink even has doorbell cams that you can add to the NVR.
Generic onvif/rtsp cams are a dime a dozen and work with any NVR program that supports open standards. We’re talking $30ish for stuff that’s weatherproof, wifi, some with backup batteries, pan tilt zoom, 2 way audio. Cheap indoor models are like $20. It all runs locally if you install one of the several free NVR programs on a computer on your LAN.
Not everyone can afford cctv
