Low-voltage systems: all BTT Engineering and Skaylink services in one place
Five areas – from building infrastructure and security to industrial automation, design and ongoing support.
Building infrastructure
For business centres, offices, retail and hotels
Security
Protecting people, assets and sites
Industry: automation and IoT
For manufacturing, transport, logistics and energy
Design and consulting
When the right decision is needed before construction
Support and monitoring
So everything keeps working after opening day
Technology infrastructure, whatever the purpose of the building
Cabling, connectivity and security systems are the foundation for the internet, firewalls, tills, cameras and workplaces. We build it so that everything works from day one.
Offices and business centres
Desk outlets, meeting rooms, Wi-Fi and access control for the whole building.
Showrooms and retail chains
Tills, cameras, background music and one standard across every store.
Hotels and restaurants
Wi-Fi in every room, key cards, public address and evacuation systems.
Warehouses and logistics centres
Perimeter protection, fibre across large sites, CCTV and monitoring.
Manufacturing and industry
Automation, IoT sensors and process metrics monitoring.
Transport and energy
Remote real-time monitoring of equipment condition and metrics.
Banks and self-service
Infrastructure for ATMs and self-service points built to the strictest requirements.
Contractors and developers
Low-voltage subcontracting and IT infrastructure design to your schedule.
BTT Engineering installs the infrastructure, Skaylink brings it to life and keeps everything running
Skaylink: network, Wi-Fi and firewall plan
Physical infrastructure and IT are planned together – from cable routes to network segments.
Skaylink: network, workplaces and hardware
Once the physical layer is in place, Skaylink configures the network, computers, Microsoft 365 and access rights.
Skaylink: security and 24/7 support
Everything works from day one, and one contact looks after the whole infrastructure from then on.
From site survey to working infrastructure in 4 steps
Survey and design
We survey the premises, align with the architect, contractor and your IT, and provide an estimate.
Installation
BTT Engineering lays the cabling and installs the systems in line with the construction schedule.
Go-live
Skaylink brings the network, firewall and workplaces live; we test and hand over the documentation.
24/7 support
We monitor the systems and respond while you get on with business.
Trusted by banks and major construction contractors
Every year BTT Engineering installs around 200 CCTV systems, 100 access control systems, 150 fire alarm systems, 100 IT infrastructure solutions and 40 electrical installation projects.
Full cycle, one partner
Design, installation, go-live and support – no need to coordinate an electrician, an installer and an IT company.
Physical security you can trust
Cameras, access control and alarms run on a separate, protected network: recordings are stored securely, access is managed and outsiders can’t connect.
Remote management
Camera feeds, access rights and event alerts on your phone or computer, wherever you are.
Standards-based, with warranty
Cabling to international standards, test reports, as-built documentation and a warranty on the work.
Built around your opening date
Cabling, internet and workplaces prepared on one schedule – the site opens on time.
Proven on the most demanding sites
Bank self-service infrastructure and projects with major construction contractors.
Frequently asked questions about low-voltage systems
Do you work as a subcontractor to the main contractor’s schedule?
Yes. We adapt to the construction phases and work from the existing design or prepare our own.
What do I receive when the work is finished?
As-built documentation, diagrams, cable test reports, an equipment list and access to the systems.
Do you maintain systems installed by others?
Yes. After a survey we assess their condition and propose a maintenance plan.
How much does it cost?
It depends on the size of the site and the systems required. After a free survey we provide an estimate.
How does CCTV comply with GDPR?
We help plan camera positions, retention periods and access rights; your company remains the data controller.
Do you provide a warranty?
Yes. The warranty covers the work performed and the installed equipment; terms are set out in the contract.
Can the systems be managed remotely?
Yes. You can see camera feeds, access rights and alerts on your phone or computer, with access configured securely by Skaylink.
We have a quote from another supplier. Can you review it?
Yes. We review the design and estimate, assess the solutions and propose an alternative – often cheaper or more reliable.
Do you work with industrial sites and IoT?
Yes. We deliver automation and metrics monitoring for transport, logistics, energy and manufacturing companies – from sensors to the data platform.
