What We Do
Our services in Belfast
Security installation in Belfast, in short
Coast Data Security installs CCTV, electric gates, intruder alarms, access control and WiFi across Belfast, from Victorian terraces near the Ormeau Road to new-build apartments in Titanic Quarter and business units off Boucher Road. Every job starts with a free site survey and ends with a walk-through of the controls and the app.
Local knowledge
Security that suits how Belfast is built.
Belfast is a city of tight terraces and busy main roads, and that shapes the way a system gets fitted. Red-brick Victorian houses around the Ormeau Road, the Holylands and Stranmillis often have a narrow front garden right against the pavement, so a camera has to cover a doorstep that passers-by walk within touching distance of, and an alarm has to work with a hallway that leads straight onto the street. Further out, in Malone and the leafier suburbs, larger detached and semi-detached houses have more room for cabling and a camera spread across the boundary.
The city centre and Titanic Quarter are different again: new-build apartment blocks and offices, where access control on the main door and a shared intercom matter as much as any camera, and where a CCTV system usually has to be specified around a management company's cabling routes rather than a free hand. Business parks off Boucher Road and around the Gasworks want cameras covering car parks and loading areas, an alarm on the unit itself, and increasingly a WiFi network that the CCTV and access control both run over.
Roads and coverage
Getting to you, wherever in Belfast you are.
Belfast City Council covers the whole of the area we work in here, and the PSNI's Belfast City district covers policing for it. The M1, M2 and M3 motorways meet at the Westlink, so a job off the Lisburn Road, the Antrim Road or the Newtownards Road is usually a short run from any direction, and a survey can normally be arranged within a few days.
A house or a unit that fronts directly onto a busy road, such as the Ormeau Road or the York Street junction, brings its own camera problem: too wide an angle picks up every passing car and van, which fills a hard drive with nothing useful, so the survey sets the field of view to cover your property and your entrance, not the traffic going past it.

Why us in Belfast
A security installer that knows how Belfast is built.
Coast Data Security Ltd installs CCTV, gates, intruder alarms, access control and WiFi across Belfast and the rest of Northern Ireland from our Castlewellan base, so a camera at the front door, an entry system on a shared block and an alarm on a business unit can all sit on one app rather than three separate logins. Every installer is fully qualified and carries comprehensive public liability insurance, and every Belfast job finishes with a walk-through of the controls before we leave.
How it works in Belfast
From your call to a finished system
- 1
Survey at your property
We come to you in Belfast, look at the terrace, apartment or business unit, check access and power, and talk through what you actually want the system to do.
- 2
Design and written quote
A clear recommendation for cameras, an alarm, a gate or access control, priced in writing, with nothing added that the property does not need.
- 3
Scheduling around the city
We fit the work in around your household or your business hours, and around any other trades if groundworks or cabling routes need coordinating first.
- 4
Installation and testing
Equipment is fitted, wired or paired, and tested properly before we call it finished, whether that is one camera or a full multi-service setup.
- 5
Handover and support
We finish by showing you the app, the keypad or the fobs and the manual overrides, then leave you with the paperwork and a direct line for anything that needs adjusting later.

Belfast security questions, answered.
What Belfast homeowners and businesses ask us.
Do you cover all of Belfast, or just certain areas?
All of it, from the Malone Road and Stranmillis to Titanic Quarter, the Holylands and the business parks off Boucher Road. Belfast City Council's whole area is regular work for us, and we will tell you honestly if a particular street is awkward for any reason.
My house is right on a busy road, will the camera just film traffic all day?
No. The survey sets the field of view to cover your property, your door and your boundary, not the cars going past. If a wider view would help, we explain why before fitting it, not after.
Can you fit access control on a shared apartment block entrance?
Yes. Paxton fobs, keypads and video intercoms are a regular job on Belfast apartment and office blocks, and we can work with a management company's existing cabling and access arrangements where one is in place.
Is there anywhere in Belfast you would not recommend a certain type of camera or gate?
Occasionally. A narrow Victorian terrace with a front door onto the pavement is not always suited to a large gate, and some new-build blocks restrict what can be fixed to a shared wall. We flag this at the survey rather than after ordering equipment.
How much does it cost to install CCTV or an alarm in Belfast?
There is no fixed price list. A terraced house near the Ormeau Road, an apartment in Titanic Quarter and a unit off Boucher Road all need different equipment, so the site survey decides the figure, and you get it in writing before agreeing to anything.
How long does an installation take?
A straightforward CCTV or alarm job is usually finished in a day. Larger jobs, such as access control across a whole office block or a gate needing groundworks, take longer and are scheduled with a realistic programme given at quote stage.
Can I view my Belfast property remotely?
Yes. Every camera and alarm we fit in Belfast connects to an app on your phone, so a look at the terrace, the apartment or the office is possible from wherever you happen to be in the city or out of it.
Do you work with letting agents or management companies?
We do. Access control and CCTV on apartment blocks and managed commercial units in Belfast often involve a letting agent or a management company, and we are used to working alongside them on specification and access.
What if my Belfast property already has a system from another installer?
Rather than insisting on a clean slate, we will look at what is already there, whether it is a camera, an alarm panel or a gate motor, and tell you plainly whether it is worth keeping, upgrading or replacing.
Do you install WiFi as well as CCTV in Belfast offices?
Yes. Titanic Quarter offices and older terraces both benefit from a proper WiFi survey, and the network we design can carry CCTV and access control traffic as well as everyday use, rather than competing with it.
Are you insured to work in commercial premises as well as homes?
Yes. Comprehensive public liability insurance and full qualification sit behind every job, whether that is a private house, a retail unit or an occupied office block somewhere in the city.
