CMX (non-rated) outdoor/direct burial cable inside on an ATTIC. NEC allows 50 feet but the cable must be terminated in an "enclosure" or "primary protector"?

I'm looking to install POE security cameras. Due to the long runs outdoors the cable needs to be UV resistant. This usually means that cable has to have a sheath that is unrated (CMX) and can't be run for long distances inside a structure. NEC allows for 50 feet indoors provided its terminated inside an "enclosure" or "primary protector".

I believe the logic behind this all comes down to fire. If lighting or a large voltage is applied to the exterior of cable it could ignite the sheath and start a fire inside the home. However, I don't know how i'm able to reasonably terminate multiple runs coming into a structure from various sides/distances all in enclosures grounded enclosures.

In my state that involves a low voltage 06 licence which means your basically an electrician. 4000 hours apprenticeship + certs, licence, bond all of it.

This could get pretty expensive and is well beyond the scope of what most home owners are expecting for security camera installs.

That said, I want to do these jobs right and was wondering what common practice is here.

Thanks.
