Ring cameras are pretty good. Limited to HD only; no 4K yet. You can run wire powered ones in the house and use the wireless (rechargeable battery packs) for outside. Get the app on your phone and you can get live views and motion alerts, too. No computer needed.
All this assuming you have internet at the location.
Edit: I see you may not have internet. I run a Lorex 4K NVR system on my house. No need for internet and you can hook it to a monitor, tv, etc. Depending on your hard drive size, it can record considerable footage. You can also set it to only record when motion is detected drastically increasing the look back period. Live view is always available.
My .02 cents. Get an NVR setup with POE capabilities. If you need wireless, they have those, too, but they are more $$.
