Had a similar situation and used the Reolink Argus PT 5MP with cellular. Was an okay experience, not great. Was able to catch one thief with it.
The camera itself had a good picture and everything, and the PTZ is a big bonus, but the solar panel that came with it died after a couple of months. It happened to be mounted to a temporary pole anyway so I was able to just plug the USB cable in to power, but still. Apparently you can buy replacement solar panels, so there's that I guess.
The cellular connection is also a bonus, as you can check in on the site while away, though you're limited to connecting via Reolink's P2P, which is quite slow and buggy in my limited experience. I bought the SIM card for it off of a site called Eiotclub.
