Types of Low Voltage Work We Install
Low voltage covers every system in a building that runs on low-voltage power or carries data, voice, video, or signaling rather than line power. These are the systems Sebastian installs for commercial, institutional, and public-sector clients:
| System | What It Includes | Where It's Used |
|---|---|---|
| Structured data cabling | Copper horizontal cabling, patch panels, racks, and termination for workstations and devices | Offices, schools, clinics, government buildings |
| Fiber optic cabling | Fiber backbones between floors, buildings, and campus sites, including underground runs | Campuses, multi-building sites, data rooms |
| Voice and VoIP | Cabling and infrastructure for phone systems | Any facility with a business phone system |
| Wireless networks | Wireless access point cabling, mounting, and coverage planning | Offices, warehouses, campuses, public venues |
| Security and surveillance | CCTV, access control, and intrusion alarm wiring | Entrances, perimeters, restricted areas |
| Fire alarm and nurse call | Low voltage fire alarm wiring and nurse call systems | Healthcare facilities, schools, public buildings |

Low Voltage Cabling for Public Agencies and Institutional Projects
Public agencies, school districts, and institutional owners in Fresno County and across California procure low voltage cabling differently than a private business does. Bids are more document-heavy, contractors have to be registered and qualified before award, and submittals are reviewed before work begins.
Sebastian is set up for that process. We hold a California contractor license (CSLB License No. 940822) and are registered with the California Department of Industrial Relations for public works, and our team has completed low voltage, fiber, and cabling work for public and institutional clients, including the Fresno State communications loop and a downtown Fresno municipal building.
For a closer look at what agencies should specify and verify before a cabling bid goes out, see our guide to Fresno County low voltage cabling procurement, along with how to hire a qualified government electrical contractor in Fresno.

What Clients Say About Us
Sebastian was able to determine the issues and make recommendations for solving those problems. We would most definitely recommend Sebastian to other colleges or businesses because of their well-rounded yet technical knowledge base, outstanding customer service, and continuing evolution of technology awareness.
Sebastian is one of the best companies I have worked with from a customer standpoint.
Sebastian is a well-recognized and highly recommended local company and a leader in the technology industry. Sebastian employees were all very gracious, friendly and technically competent. They were very quick to address our concerns.
Sebastian did a great job and I would use them again to run or fix fiber optic cables. Their team was very professional and did very clean work.
Karlene was a pleasure to work with and kept me updated during the entire process until the job was complete. I’ve worked with others in this industry and none compare to her experience or her professionalism!!
We are extremely appreciative and impressed not only with the work Sebastian has completed at Fresno State so far this year, but also the flexibility and commitment. We continually hear great things about Sebastian and are very excited to work with us on a new campus wide Access Point project.
