Thank you for the replies yesterday about my drill. I think I’m going to get a cheap corded SDS drill and some big bits. This is what I need to feed through the wall and there is no way to detach the cable from the camera and feed it the other way. I know it needs to be weather shielded, but this is a mad amount of connectors!
If I need to solder anyway I would be unsoldering at the camera end. No cutting that way, no compromise to the cable. It is probably a pita though.
