Security camera for Holiday Chalet advice please.

[Brad55]

Not very tech-minded, so I need some advice please.

Have a holiday chalet which I would like to keep surveillance on throughout the year.

My problem is not there all the time and only a 8-month season. So no electricity or Wi-fi for a lot of the year.

Is solar power the way ?
No monthly Fee.
Just a cheap basic camera that I can see Human Detection on.

Thanks.
