I understand your concern as well since I live close to a high crime area. They do make security cameras that can be used in an RV and do not require Wi-Fi. It is built into the camera. They are around $400 each but also have motion detectors built in. The cameras will send an alert to your cell phone if there is any activity in or around your RV. You can also use the app you install on your cell phone to view inside and outside your RV when you are away. These cameras work in most remote areas. This is a huge stress reliever to see that everything is OK and allows you to calm down and enjoy yourself. Search security cameras on this website or at your local electronics store to see which camera would best fit your needs.
