CWC Security, LLC · Serving Nassau & Suffolk County
CWC Security installs low voltage and structured cabling for homes and businesses across Nassau and Suffolk County. We run, terminate, label, and certify the wiring behind your network, security cameras, alarms, access control, Wi-Fi, phones, and smart-home systems, from a single room to a multi-building campus or data center. Every job is tested end-to-end with a Fluke certified scanner and backed by a cabling warranty.
What Is Low Voltage Cabling?
Low voltage cabling is the wiring that carries data, video, and signals rather than standard electrical power. It covers network cable (Cat5e, Cat6, Cat6A), fiber optics, coaxial cable, and the wiring for security cameras, alarm sensors, card readers, intercoms, Wi-Fi access points, and phone systems. Because we also install and service those systems, we design the cabling around the equipment it will feed, not just the walls it runs through.
What We Wire

Low Voltage Wiring for Businesses
For offices, retail, schools, and commercial buildings, we work directly with construction contractors throughout New York on new construction, build-outs, and office moves. We look at potential failure points up front and design alternate or redundant paths so a single cut cable doesn't stop your business.
Low Voltage Wiring for Homes
For homeowners building, renovating, or finishing a basement, prewiring is the cheapest moment to get it right. We run network, camera, alarm, and TV/AV wiring while walls are open, so your cameras, Wi-Fi, and smart-home gear work cleanly from day one with no exposed cable. See our residential security page for the systems we install.
