Outdoor Siamese Cables for Professional Surveillance and Perimeter Security
Windy City Wire Outdoor Siamese Cables combine RG59/U coax with an 18/2 power pair in a single, rugged assembly designed for outdoor and direct-burial installations. This construction gives security integrators and electrical contractors a dependable way to carry high-quality video and camera power on one pull, reducing installation time while maintaining signal integrity over distance. The RG59 video leg uses a solid bare copper center conductor with a high-coverage bare copper braid, and the power leg features stranded copper conductors sized for stable delivery to cameras, housings, IR illuminators, and accessories.
Purpose-built for demanding environments, these outdoor cable assemblies support consistent performance in trench-to-pole runs, building-to-building pathways, and exposed exterior routes when properly installed per code. The discreet black jacket blends along fence lines, parking lots, and facility exteriors for a clean, professional appearance.

How This Outdoor Wire and Cable Supports Your Project
Outdoor Siamese Cables are engineered to help B2B teams deliver dependable surveillance results with fewer pulls and fewer failure points. They are a practical choice when upgrading legacy analog sites, extending HD-over-coax coverage, or deploying cameras where trenching and direct-burial routing are the most efficient path. If your project calls for a durable outdoor cable that simplifies camera power and video distribution in one run, this category is designed for that need.
For help with takeoffs, specifications, and integration planning, contact Windy City Wire. Our team can support design and installation goals across security, facilities, and construction environments.
These Outdoor Siamese Cables combine RG59/U video with a 20 AWG solid bare copper center conductor and an 18 AWG stranded copper power pair (18/2). The coax is shielded with a 95% bare copper braid; the power pair is unshielded. Designed for direct burial CCTV/video surveillance applications.
Available colors are Black (stock). SmartWire also supports custom jacket and stripe color combinations to help standardize and identify your installations—contact Windy City Wire for customization options.
The RG59/U video conductor is 20 AWG solid bare copper for optimal signal integrity, while the accompanying power leg is 18 AWG stranded copper (18/2) for flexibility and durability. All SmartWire cables come standard with SmartWire Glide lubrication applied to the jacket to reduce pull friction.
At Windy City Wire, we manufacture and stock SmartWire Outdoor Siamese Cables in 1,000 ft lengths as our standard length.

RG6 typically has a larger center conductor and thicker dielectric than RG59, delivering lower attenuation and better high‑frequency performance—ideal for longer runs, broadband, and satellite/cable TV. RG59 (often 20 AWG) is more flexible and is commonly used for shorter CCTV/video surveillance runs. RG6 often offers heavier or quad shielding options; RG59 commonly uses standard braid/foil shielding. Terminations also differ by application (e.g., BNC for CCTV vs. F‑type for CATV/SAT).
RS‑232 is single‑ended, point‑to‑point, short‑distance, and typically uses 3–5 conductors—best for device‑to‑device links. RS‑485 is differential, supports multidrop networks (many nodes on one bus), longer distances, and typically uses a 120‑ohm balanced twisted pair with an overall shield recommended. BACnet is an application‑layer protocol; in building automation it commonly runs as BACnet MS/TP over RS‑485 (so it uses RS‑485‑type twisted pair cabling) or as BACnet/IP over Ethernet (Category‑rated copper or fiber).
