Cables that are UV treated, such as Lorex's Shielded CAT6 Extension Cable, are the best option when running cables outdoors. Their UV treatment offers protection from the elements and prevents degradation over time. These cables can also be run directly underground without the need for a conduit (required to be buried at a depth of at least 24 inches).
If you need to run other cables, such as non-UV treated CAT5e or BNC security camera cables outdoors, it is important to do so safely. It is highly recommended that either overhead or underground cables be covered in a properly installed/grounded PVC sheltered conduit and follow NEC guidelines for proper entrance protection. A weatherproof RJ45 Cable Gland* can be used to provide weather-resistance and protection from dust, dirt and other environmental contaminants for exposed ethernet connections (shrink tape or electrical tape may be required for BNC connections).
The NEC also requires specific distances for both overhead and underground cables. If burying the cable underground in a PVC conduit, the required depth is at least 18 inches from the ground (a metal conduit can be as shallow as 6-inches). Before you start to dig, it is recommended that you call your local utility company to perform a brief property inspection for your safety. If running cables overhead, the required height is a minimum of 10 feet overhead.
