Best security cameras for travel trailer?

Thanks for the tips and feedback guys. I just moved out of my apartment in Portland Oregon because it was a bottom floor apartment with a door that connected to the street - had over 10 different weirdo drug addicts/criminals knock on that door, mostly in the middle of the night. After I installed Blink security cameras at that door, just seeing the camera and that they were being recorded scared off about 90% of the weirdos. Unfortunately we still have an office in Portland Oregon that I need to go to sometimes, but if you're familiar with the area you know it's basically a giant homeless encampment now with drugs and crime everywhere. The RV parks that are near the office are also near some of these sketchy homeless campgrounds, and after my experiences with the security cameras at the apartment, I feel that cameras on the trailer might be a good idea. Knock on wood I haven't had any really bad experiences yet, the only thing that's ever happened was my spare tire cover was stolen from the back of the trailer when I was boondocking in Florida. Also when I was boondocking in Florida I noticed hand prints all over the small door on the outside that leads into the storage area under the bed and suspected someone tried to get inside the trailer. It would have been real nice to have recordings of both of these events. The crux of the issue as you guys pointed out is an internet connection especially a stable one that can be used to give a consistent signal to the cameras. The Starlink internet is great... when there are no trees. My T-Mobile phone service and hotspot works most of the time but not always. Will have to figure this one out.
