Full open source and private camera monitoring system

I want to setup a camera monitoring for my house and some rooms. I need to bee able to view the cameras remotely and and also do recording if possible. I could find some camera brands like dahua cams but having briefly tested them they. Seem to rely on acwmtralized cloud and proprietary visualization software.

What are you recommendation? This is not a professional setup I would at max have 3 cameras.
