Low voltage technicians install and maintain systems running below 50 volts: structured cabling, access control, video surveillance, AV, fire alarm, and building automation.
Many commercial buildings now hold more low voltage infrastructure than traditional power wiring, and demand has grown steadily alongside the smart building and integrated systems market.
$48,000 to $82,000 per year, depending on specialty and certification level.
Structured cabling, access control, CCTV/surveillance, AV integration, BAS/BMS, and fire alarm.
BICSI RCDD or Installer, CompTIA Network+, Leviton/Panduit manufacturer certs, and NICET for fire alarm.
Growing; smart building systems and IoT device proliferation are driving demand.
Low voltage contractors, AV integrators, security systems firms, and building automation companies.
The smart building market is expanding fast, and commercial property owners keep investing in integrated security, automation, and AV infrastructure. Techs who work across multiple system types, especially those who can both install and program, are commanding higher pay.
Data center work has also created sustained demand for structured cabling specialists who understand the density and performance requirements of mission-critical environments.
Often require BICSI or manufacturer certifications.
May require state licensing in some jurisdictions.
Increasingly requires familiarity with BACnet, Modbus, and IP networking concepts.
Expected given the travel involved across sites.
Strong troubleshooting and customer communication are valued across every low voltage specialty.
