Oh yes - run Frigate on a mini PC or home server. It runs best in Docker. And it should work with any cameras that support RTSP and provide H.264 video.

I'm not affiliated btw, but I found the instructions really useful - they walk you through an install of Debian 13 (small version of the OS with minimal components), set up low maintenance options (auto updates etc.), install Docker & Frigate, and set up your cameras for best performance depending on your needs.

Keep everything local (if you want). I also integrate with HomeAssistant and expose that through a free CloudFlare Tunnel for access when away from home.

CloudFlare tunnels by the way - these are a great solution to accessing home-network resources without punching holes / port-forwarding etc. because all the access is outward from the home network, then an authentication layer added by CloudFlare.
