I picked up a Reolink Go 4G LTE Mobile Outdoor/Indoor Battery/Solar Powered Security Camera. Added a T-mobile SIM for $10 plus $10/month. It only uses bandwidth when you're watching it live, or when it's capturing motion. You can mount it anywhere in or on the boat and get an alert when motion is detected, or just open the app to check on things in 1080p video.
This is the interior of my boat today. It's monochrome because it's in IR mode. The boat is on the hard under a winter cover, and if someone enters I'll get a photo of their face and video plus an alert. It uses a USB power cord, and I'm powering it from the house bank, which is solar-maintained.
I also have a BoatCommand system to monitor the bilge pumps/battery and receive geo-fencing alerts.
