What Does a Security Systems Technician Do?
Whether the building is a dorm, a hospital, or a data center, its owners need to control who gets through each door and see what happens at the entrances. Security systems technicians install and service the card readers, cameras and alarms that make that possible, working for security contractors and in-house campus teams. In the case of a new hire, the task might be something as simple as setting up a badge that opens the right doors.
Also known as: Electronic Security Technician
Security Systems Technician Duties and Responsibilities
The primary responsibilities of a security systems technician include:
- Install card readers, electric strikes and door contacts, and wire them back to access panels.
- Mount and aim IP cameras, then add them to video software such as Genetec or Milestone.
- Program cardholder schedules and door groups in access systems such as Lenel OnGuard or Genetec Synergis.
- Pull and terminate network and low-voltage cable through ceilings, walls and conduit.
- Test intrusion alarms, panic buttons and motion sensors, and fix false alarm sources.
- Troubleshoot offline readers, failed power supplies and cameras that drop off the network.
- Replace backup batteries and power supplies on a set maintenance schedule.
- Set up intercoms and emergency call stations at entrances, garages and parking lots.
- Document device locations, IP addresses and wiring so the next technician can find everything.
- Train security officers and building managers to pull video and manage badge access.
Required Skills and Qualifications
To succeed as a security systems technician, you will need the following skills and qualifications:
- Low-voltage wiring and termination
- IP networking, including VLANs and power over Ethernet (PoE) switches
- Access control and video software such as Lenel OnGuard, Genetec or Milestone
- State low-voltage or alarm license where required
- Manufacturer certifications for the systems you install
- Discretion around security details and camera footage
- Tidy, labeled cable work
- Customer service with facility and security staff
Education and Training
Security contractors want people who can pull cable neatly and pick up new software quickly. Electrical, IT and audio-visual backgrounds all carry over, and the training usually runs several months on the job once you are hired. Many states require a license for alarm work, and manufacturers such as Genetec and Milestone run certification courses on their own products.

BLS projects employment of security and fire alarm systems installers, the group that includes security systems technicians, to grow about 7 percent from 2025 to 2035. In fact, it expects about 8,500 openings a year, as more buildings trade keys for badges and add cameras to parking lots and entrances. Technicians who understand networks as well as wiring are more likely to move into lead and design roles.
