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.
