Network Security Systems Installer Career Guide UK
What a network security systems installer does in the UK, from IP CCTV to access control and alarms, the routes in, the networking skills and standards employers want, and pay by specialism.
By Tony Musso on
A network security systems installer fits and configures security equipment that runs over a computer network: IP CCTV cameras and network video recorders, access control systems that open doors with cards, fobs or phones, and intruder alarms that report to a monitoring centre over the internet. Most installers learn through the Level 3 fire, emergency and security systems technician apprenticeship or move across from electrical or IT work. Our career data puts pay at around £24,000 to £28,000 to start, £32,000 to £45,000 with experience and £50,000 to £65,000 for senior and integrated systems engineers.
This guide focuses on the networked side of the job: what it adds to traditional alarm and CCTV work, the skills employers test for, the routes in and how pay changes as you specialise. For the general installer route, including GCSE requirements and the apprenticeship, see our security systems installer career guide.
What makes it "network" security
Older security systems ran on their own cables: analogue cameras wired to a recorder, alarm sensors wired to a panel. New installations increasingly run over the same kind of network as office computers. Cameras are powered and connected through one network cable using Power over Ethernet (PoE). Door controllers talk to a server or cloud platform. Alarm panels signal to a monitoring centre over broadband or mobile data.
That changes the installer's job. As well as fixing equipment to walls and running cable, you set IP addresses, configure switches, plan how much bandwidth and PoE power a system needs, set up secure remote viewing for the customer and keep firmware up to date. A badly set up camera can expose a customer's network to the internet, so security of the devices themselves is now part of the work.
A typical week
Most installers work from a company van, travelling to two or three sites a day or spending several days on one larger project.
- New installations: running and terminating network cable, mounting cameras, readers and detectors, and building out equipment racks.
- Commissioning: configuring recorders, cameras and door controllers, testing every device and recording settings for the customer's handover pack.
- Service visits: routine maintenance on alarm and CCTV systems, which approved companies carry out on a schedule.
- Fault calls: tracking down why a camera has dropped off the network or a door will not release, often using a laptop as much as a screwdriver.
Many employers run a call-out rota, so some evening and weekend work is normal.
Routes into the job
Apprenticeship. The Level 3 fire, emergency and security systems technician apprenticeship is the most direct route. It usually takes two to four years, you are paid throughout, and you learn security systems alongside fire alarm and emergency lighting work.
From IT networking. People from IT support or network roles already understand IP addressing and switches. They add practical installation skills, the security standards and manufacturer training, and often move quickly into commissioning work.
From electrical work. Qualified electricians bring safe working practice and cable skills, and add networking knowledge and security product training to specialise.
Installer's mate. Some people start as a cable puller or installer's mate with a security company and train on the job, adding short courses as they go.
Skills and certifications employers look for
- Networking: IP addressing and subnets, VLANs, PoE power budgets and secure remote access. CompTIA Network+ or Cisco CCNA are useful ways to prove it.
- Standards: intruder alarms are designed to BS EN 50131 and video surveillance to BS EN 62676. Many customers require their installer to be certified by the National Security Inspectorate (NSI) or the Security Systems and Alarms Inspection Board (SSAIB), and alarms that call a police response must be installed by a certified company.
- Security screening: companies working to these schemes vet staff to BS 7858, which normally covers your employment history over the past five years.
- Site cards and working at height: a CSCS or ECS card for construction sites (our CSCS test guide explains the test), plus IPAF or PASMA training for mobile platforms and towers.
- Manufacturer training on the specific cameras, recorders and access control platforms your employer installs.
- A full driving licence, since most roles come with a van.
Pay by specialism
Our career data shows how pay varies by the systems you work on:
| Specialism | Typical pay |
|---|---|
| CCTV | £28,000 - £45,000 |
| Intruder alarms | £30,000 - £48,000 |
| Access control | £32,000 - £52,000 |
| Integrated systems (CCTV, access and alarms together) | £38,000 - £60,000 |
Integrated systems work pays the most because it combines all three product types with network design and commissioning. Overtime and call-out payments can add to basic pay.
Where the job can lead
With experience, installers move into commissioning engineer, service engineer or team leader roles. Those with strong networking skills can become systems designers or pre-sales engineers, specifying systems for large sites, or move into project management. Some set up their own installation business; to take on police-response alarm work and many commercial customers, the company itself needs NSI or SSAIB certification. Others move sideways into fire alarm engineering or security consultancy.
Is it the right job for you?
It suits people who enjoy practical work and technical problem solving in equal measure. You will spend time in ceiling voids, plant rooms and on ladders, and drive a lot, but you will also spend hours configuring equipment on a laptop. If you enjoy the networking side more than the site work, IT support or network engineering may suit you better; if you are unsure, Career Compass compares how hands-on and technical roles fit your interests.

Frequently asked questions
What does a network security systems installer do?
They install and configure IP-based security systems: networked CCTV cameras and recorders, access control and intruder alarms. As well as fitting equipment and running cable, they set up the network side, including IP addresses, switches, power over Ethernet and secure remote access.
How do I become a network security systems installer in the UK?
The most direct route is the Level 3 fire, emergency and security systems technician apprenticeship. You can also move across from IT networking or electrical work, or start as an installer's mate, then add manufacturer training and networking qualifications.
How much does a network security systems installer earn?
Our career data puts starting pay at around £24,000 to £28,000, experienced installers at £32,000 to £45,000 and senior or integrated systems engineers at £50,000 to £65,000. Access control and integrated systems work tend to pay the most.
Do I need networking qualifications to install security systems?
They are not legally required, but employers increasingly want installers who understand IP networks. CompTIA Network+ or Cisco CCNA, plus manufacturer training on the products you install, make you much easier to hire and promote.
Do security systems installers need an SIA licence?
Usually not. SIA licences cover roles such as security guarding and monitoring public space CCTV. Installing and maintaining systems normally falls outside SIA licensing, but companies working to NSI or SSAIB schemes will screen you to BS 7858.
