Greenwich, Sydney
In-building systems designed as one.
Security, data, AV, DAS and fibre — designed, installed and kept live by one team. The same stack the market already buys, run as a single programme.

Disciplines
Seven disciplines. One contractor.
The work clients already tender across security and comms houses — held together so the ceiling is opened once and the network is designed once.
Protect
Security systems
CCTV, access control, intercoms, alarms, LPR/ANPR, gates and barriers — designed as one security layer.
Connect
Data & communications
Structured cabling, fibre, voice and data centre pathways built to carry whatever the building needs next.
Collaborate
Audio visual
Meeting rooms, video walls, digital signage and wayfinding that people will actually use.
Coverage
Distributed antenna systems
In-building mobile coverage — design, construct, test — independent or telco-led.
Backbone
Fibre & GPON
Passive optical networks, fibre distribution and FTTx for campuses, towers and precincts.
Converge
Integrated networks
One network for data, Wi-Fi, security, BMS, CCTV and access — designed, segmented and supportable.
Hardware
Locksmith & hardware
Master key, electronic locks, door hardware and the physical half of access control.
Why CIISEC
Built by people who have already delivered this work.
We started CIISEC to run in-building systems the way clients ask for them: one team, clear reporting, and no maze of subcontractors. Greenwich-based, Australian owned, licensed for the trades we put on a site.
About the companyOne partner, full scope
Security and comms for builders, electricians and client-side PMs — no subcontracting, no handovers. One programme from day one.
In-house crews
Design, install and commission with our own people. We quote transparently, document the job, and reduce rework instead of hiding a fourth-party behind a cover sheet.
Standards first
Gallagher, Milestone, LPR, ICT — platforms we actually install. Shop drawings, test results and as-builts are part of the job, not a nice-to-have.
Kept live
Handover is not the end. Preventative maintenance, after-hours response and a technician who already knows the plant.
Clients
We work directly with builders, electricians, developers and client-side project managers.

How we work
A programme you can hold us to.
01
Discover
Site survey, existing plant, constraints, and what ‘done’ actually means for operators — not just for practical completion.
02
Design
Shop drawings, hardware schedules, network architecture and a programme that fits the head contractor or the live environment.
03
Deliver
In-house install, coordinated with other trades. Clean containment, labelled plant, daily reporting that a client can read.
04
Commission
Test, certify, train. Credentials, as-builts and a walkthrough with the people who will run the system at 6am.
05
Maintain
Preventative schedules, monitored plant, and a call path that does not bounce you through a call centre in another timezone.
Sectors
The buildings we know.
Education
Schools and tertiary campuses that need safe access, campus fibre, and CCTV that stands up to a Department audit.
High-rise residential
Towers where intercoms, access, CCTV and fibre risers have to work for residents — and for the building manager at 11pm.
Healthcare & hospitals
Hospitals, clinics and residential care where lockdown, duress and data have to work around live operations.
Airports & transport
Terminals and precincts that need coverage, camera networks and comms plant that stay up under operational pressure.
Government & defence
Sites with real standards, real scrutiny and no appetite for a contractor who learns on the job.
Commercial property
Workplaces and commercial assets where security, Wi-Fi, AV and fibre have to land on the same programme.
Industrial & logistics
Warehouses and distribution centres that need perimeter control, LPR, fibre and cameras that can see a yard at 2am.
Hospitality, gaming & entertainment
Hotels, theatres and venues where cameras, access and coverage have to work on the night — not just at commissioning.
