Cut a hole in the gib on the inside just below where the existing cable is,
Once in the wall you can have a poke around to see whats in there.
You should be able to extend the cable down to a doorbell location.
Or you can split it into two 4-pair cables each capable of 100mbits and have one for a doorbell and one for a higher mounted camera.
Use the access panel to cover the hole you made in the wall and access it it in the future if needed.
I use them quite regularly.
They work well in garages or places where the wall doesnt need to be patched back up again, but you dont want to leave an ugly hole in the wall.
Here are some photos to show you an example....
Customer's got a new house built. Electrician ran some cat6 cable out to our ETP box but the cable hanging out the wall got damaged. It wasnt long enough to reach outside.
No attic crawl space so i couldnt run a new cable.
So I cut a hole on the inside, spliced the cable on to a new one to make it longer and poked that back through to the ETP outside.
You could do something similar.
Sounds like I need to hire you hahaha.
I like this idea. Running the cables through the cavity is nicest in terms of not having to cut through the wall and then get through insulation etc. But your solution is probably easier and probably more maintainable also.
