Here are some steps you can take to run Cat6 CCTV cable outside:
Plan the route: Keep the route as short as possible to make burial easier.
Prepare pipes: Get ready pipes like metal conduit or PVC.
Mark drilling points: Mark where you need to drill holes.
Bury the pipes: According to the National Electric Code, PVC conduit needs to be buried at least 18 inches, and metal pipes need to be buried at least 6 inches.
Run the cables: Use fish tape to pull the wires through the pipes.
Protect the cables: Use wire guard, PVC, or metal conduits to shield the cables from weather, animals, and people.
Fasten the wires: Use cable staples with rubber-lined holes every 12–18 inches to fasten the wires.
Seal connections: When moving from outdoor to indoor wiring, seal all access points and wire connectors to prevent moisture from getting in.
Use durable sheathing: The outer polyethylene jacket of the cable should be able to withstand rain, snow, sun, and temperature extremes.
Cat6 shielded cable is usually best for outdoor networking, especially when placed underground. The Telecommunications Industry Association (TIA) and Electronic Industries Alliance (EIA) standards recommend a maximum cable segment run length of 328 feet (100 meters) for Cat6, Cat6a, Cat5, and Cat5e cables.
