new here but quick question with out any answer i've since found on the forum  
  
have to run security cameras on the exterior of a church built out of stone, brick, and concrete with no attic except unfinished basement 
  
what is the best way to protect my wires inside of the conduit.  
  
the only way i can think is to run a larger diameter pvc pipe and the section 8 feet from the ground insert a emt pipe inside the larger diameter plc pipe to create a water tight seal but creating a more durable cut resistant pvc conduit  
  
any ideas other than this?
