Poorly Installed Cabling Costs More Than the Installation
Low voltage cabling is the physical foundation of every device on your network. When it's done wrong — wrong cable category, improper terminations, inadequate testing — the problems compound and become expensive to fix.
Virginia requires a Class A Contractor License for low voltage work and a separate DCJS Electronic Security Business License for any security system installation. These are two distinct state requirements. Unlicensed work can void warranties, fail inspections, and expose property owners to liability.
- Network slowdowns from marginal or untested cable runs
- Failed inspections and downtime from uncertified work
- Expensive rework when technology requires proper cabling
- Security system liability from non-DCJS-licensed installers
- Voided warranties from unlicensed contractor work in Virginia

Why Virginia Requires Two Separate Licenses for Security System Work
Most property owners don't realize that electronic security system installation in Virginia is governed by two distinct licensing bodies. The Virginia DPOR Class A Contractor License covers low voltage and cabling work. The Virginia DCJS Electronic Security Business License specifically covers the design, installation, and service of electronic security systems — CCTV, access control, alarms, and intrusion detection.
A contractor holding only a Class A license is not legally permitted to install electronic security systems in Virginia without also holding a DCJS license. Mercury Communications holds both — Class A #2705165655 and DCJS Electronic Security Business License #11-30083 — and all field technicians performing security system work are individually registered with DCJS. Hiring a single-license contractor exposes property owners to code violations, voided warranties, and failed inspections.

Low Voltage Cabling — Frequently Asked Questions
Common questions from homeowners, facilities managers, and general contractors.
Low voltage cabling refers to electrical systems operating below 50 volts, including structured data cabling (Cat6, Cat6A, fiber optic), security camera wiring, access control, audio/video distribution, and intercom systems. Unlike standard electrical wiring, low voltage cabling requires a specialized licensed contractor in Virginia.
Yes. Virginia requires a Class A Contractor License for low voltage and electronic communications service contracting. Mercury Communications holds Virginia Class A License #2705165655 and is bonded and insured. Unlicensed installations can void equipment warranties, fail inspections, and create significant liability for property owners.
Yes — and this is something many property owners don't verify before hiring. Any company installing, servicing, or maintaining electronic security systems in Virginia — CCTV cameras, access control, alarm systems, and intrusion detection — must hold a Virginia DCJS Electronic Security Business License in addition to a Class A contractor license. These are two separate state requirements. Mercury holds both: Class A #2705165655 and DCJS Electronic Security Business License #11-30083. All field technicians performing security work are individually registered with DCJS.
Cat6 supports 10 Gbps up to 55 meters. Cat6A (Augmented Category 6) supports 10 Gbps up to the full 100-meter channel length with better crosstalk rejection — preferred for new commercial installations and future-proofing. Mercury recommends Cat6A for most commercial builds and Cat6 for standard residential applications where budget is a consideration.
A small office (10–25 drops) typically takes 1–2 days. A medium commercial space (50–100 drops) typically takes 3–5 days. Large enterprise or multi-floor installations are scoped individually after a site survey. Mercury provides detailed project timelines before work begins so facilities managers can plan accordingly.
Yes. Mercury installs singlemode (OS2) and multimode (OM3/OM4) fiber, performs fusion splicing and mechanical terminations, certifies runs with OTDR testing equipment, and provides FTTx solutions for indoor, outdoor, and direct-burial applications.
Yes. Mercury holds USAC E-Rate SPIN #143054774. Structured cabling, managed Wi-Fi, and network switches are eligible for E-Rate Category 2 funding — up to 90% discount for qualifying K-12 schools based on NSLP percentage.
Yes. Mercury operates from Winchester, VA (serving Northern Virginia, Shenandoah Valley, and the I-81 corridor) and Virginia Beach, VA (serving Hampton Roads, Norfolk, Chesapeake, and Suffolk). Both offices serve clients throughout the full Commonwealth of Virginia.
