I used a Reolink Argus with a battery and Wi-Fi connection. The one I used is probably EOL now, but a quick look at the site shows even solar chargeable options. So, it is possible.
I've got a Reolink Argus 2E which look like it's been replaced by the 3E, but it works great without any wired connection to the house. I've got it solar powered and strapped to a tree, unprotected by the elements. 2 years and still working.
