I am looking for a DIY or otherwise extremely cheap solution to install 3 motion-activated cameras outside my house, to watch each door and the garage.

I have seen many different methods online for setting up your own cameras and security systems, but I’m not sure which would be best. So, I’m wondering what all of you think.

Specifically, I would like a system that works similar to Ring in that I can choose the motion zones and access the camera feeds from a mobile app. I would prefer if they were able to be solar+battery powered, though just rechargeable batteries would be fine if solar ends up being too expensive. And while I am tech savvy, my mother who also lives in the house is not. So while the setup can be as complex as necessary, I would prefer if accessing the feeds is as simple as possible.

Does anyone know what best fits my needs, or if something like this even exists?

Thank you for your time and responses!
