Choosing a home security system in Ireland used to mean one phone call to the biggest name you knew. Now there are local installers and national providers in every city, and the systems themselves range from a simple wireless alarm to cameras, sensors and smart home control. More choice is good, but it makes the shortlisting harder.
This shortlist does the narrowing for you. It covers eleven companies across Dublin, Cork, Galway, Limerick and Waterford, with a note on what each one does and where it is based. It is an editorial shortlist, not an official ranking: we researched publicly available information and used our judgement.
#1. MJ Flood Security
MJ Flood Security leads our shortlist, and it is the first conversation we would suggest having. The company is based at Baldonnell Business Park in west Dublin, with the N7 and M50 close by, so most of Dublin and the commuter counties are within easy reach.
Its work covers both sides of home protection: closed circuit television on the security side, and fire alarm and fire protection systems on the safety side. That breadth makes it a practical single point of contact if you would rather have cameras, intruder detection and fire safety handled by one company instead of three.
For homeowners in Dublin and the surrounding counties who want a survey and a system fitted around the house they actually live in, this is a strong place to start. A company that handles security and fire protection together can also save you time when you are planning the whole setup.

#2. Securigard Alarms Dublin.
South Dublin is well covered on this list. Securigard Alarms Dublin is based in Rathfarnham, which makes it convenient for homeowners in nearby areas like Templeogue, Terenure and Knocklyon, as well as the wider south side of the city.
The company is a security system installer, so its work is the supply and fitting of intruder alarms and related home security equipment rather than retail-only sales. For most households that is the service actually needed: someone to assess the doors, windows and rooms, then fit a system that covers them.
A locally based installer suits anyone who prefers dealing with a company from their own part of the city. If that is you and you are in south Dublin, Securigard is worth considering. Its place on this shortlist reflects a solid local standing.

#3. Gibbons Security Systems & Electrical
Turners Cross is just south of Cork city centre, and that is where Gibbons Security Systems & Electrical is based. The location is convenient for the whole of Cork city and its suburbs.
The business combines two trades under one roof: it is an electrician as well as a security system installer and fire alarm supplier. That pairing is genuinely handy during a renovation or rewire, because the cabling for an alarm or cameras can go in while other electrical work is already being done.
Even on a straightforward alarm job, having electrical expertise in the same company removes one moving part from the project. For Cork householders planning work on the house anyway, or anyone who likes the idea of a single contractor for both trades, Gibbons is a useful name on this shortlist. The combined offering is what earns it a place here.
- Address: 2 &, 2A Congress Rd, Turners Cross, Cork, T12 N5KC
- Phone: +353214847615

#4. Pro Security
Galway’s Royal Rock Industrial Estate, on the east side of the city, is the base for Pro Security. From there the company is well placed for Galway city and the main routes into the county.
It spans three categories: burglar alarms, closed circuit television and fire alarms. For a homeowner, that means intruder detection, cameras and fire detection can all be discussed in one conversation, with one supplier responsible for the lot. Fewer suppliers also means fewer numbers to call if something needs attention later.
That breadth is the main reason it features here. If you live in Galway city or county and want alarms, cameras and fire detection from a single local company, Pro Security is worth a look. It is also a handy first call if you are fitting out a new build and want everything specified together.
- Address: Unit 5, Royal Rock Industrial Estate, Galway, H91 YN72
- Phone: +35391766639
- Website: prosecurity.ie
#5. Mc Cann Security Systems
Mc Cann Security Systems operates from Hogan Avenue in Prior’s Land, close to Limerick city centre. That central base makes it a convenient option for homes across the city and suburbs.
The company is a security system installation service, the category most householders are actually shopping for: someone to look at the property, recommend an alarm setup and fit it properly. A city-based installer also keeps travel distances short if the system ever needs a service or an adjustment.
If you are in Limerick and prefer dealing with a locally based installer, this is one to add to your list. Gathering a quote here alongside one or two others is the simplest way to check you are being quoted fairly. Its place on this shortlist reflects an established local presence.
- Address: 26 Hogan Ave, Prior’s Land, Limerick, V94 HXV7

#6. JEC Security Limited
JEC Security Limited is based in the Waterside area of Waterford city. From there the city is on its doorstep and the wider south east is within easy reach.
As a security system installer, the company supplies and fits intruder alarms and related home security equipment. Installers in this category will typically walk the property with you first, so expect a conversation about doors, windows and the rooms you want covered before any equipment is agreed.
For Waterford householders collecting quotes, JEC is a sensible local name to include. A nearby installer is also practical for the lifetime of the system, since alarms occasionally need servicing or a sensor replaced. Its local presence is what earns it a spot on this shortlist.
- Address: Waterside, Waterford
- Phone: +35351371411

#7. HomeSecure – Protecting Your World
The name tells you the focus: HomeSecure is about protecting the home. The company works from Sandyford Business Park in Dublin 18, a convenient base for the south Dublin suburbs, from Dundrum and Stillorgan out to Leopardstown and Stepaside.
It is listed as a burglar alarm store, so residential intruder alarms are its core category rather than a sideline. For a homeowner, dealing with a company whose whole focus is home alarms keeps the conversation simple: houses like yours are what it works on. That single-category focus is the reason it features on this list.
Sandyford is also easy to reach from the M50, which helps if you are coming from further afield in south Dublin or north Wicklow. If you want an alarm-focused supplier close to home, HomeSecure is worth considering.
- Address: Unit 5, Burton Hall Rd, Sandyford Business Park, Dublin 18, D18 P702
- Phone: +35314851744

#8. PhoneWatch – Home Security Experts Across Ireland
PhoneWatch’s own description is home security experts across Ireland, and an Ireland-wide remit sets it apart from the local installers on this list. Its registered base is Block 1 of the Irish Life Centre on Abbey Street in Dublin 1.
The business covers three categories: burglar alarms, fire alarms and security system installation. That means it spans both the supply of the equipment and the fitting of it, so the whole job can sit with one company from quote to commissioning. Covering fire alarms as well as intruder alarms also lets you handle both safety jobs together.
A national footprint suits readers who move house, own a second property elsewhere in Ireland, or simply prefer a provider that operates everywhere rather than in one city. If that is your preference, PhoneWatch is a natural name to include in your comparisons.
- Address: Block 1, Irish Life Centre, Abbey Street Lower, North City, Dublin 1, D01 Y7V2
- Phone: +35315827920
- Website: phonewatch.ie/?utm_source=googlemybusiness&utm_medium=organic&utm_campaign=Google%20My%20Business
#9. Deady Security
Cork’s southside gets its own specialist here. Deady Security works from Metro Business Park at Frankfield, which is convenient for Douglas, Grange and the southern suburbs, with the South Ring Road close by.
The company is a security system installer, supplying and fitting home security equipment for local homes. As with any installer, much of the value sits in the survey and the placement of sensors, not just the box on the wall.
Cork householders who would rather deal with a locally based installer than a national provider should put Deady Security on their quote list. Two quotes from two different Cork companies will tell you far more about fair pricing than any website will.
- Address: unit 7, Frankfield, Metro Business Park, Cork, T12 HX47
- Phone: +353214375634
- Website: deadysecurity.ie
#10. Securecom – Alarms, CCTV
Home automation is part of the mix at Securecom, which sets it apart from most names on this list. The company is based in Claregalway Corporate Park, just outside Galway city, so it suits homes in the city and across the county.
Alongside automation, its categories include closed circuit television and fire alarms, with alarms and CCTV flagged in the name itself. Home automation as a category covers things like checking cameras or controlling lighting and heating from your phone, so if a smarter setup appeals, a company listing it as a line of work is a sensible starting point.
For Galway homeowners weighing a straightforward alarm against something more connected, Securecom is a useful conversation to have before you decide. Claregalway is also a straightforward drive from most of the county via the N17 and M6. Its place on the shortlist comes from that combination of security and smart home work.
- Address: Unit 25C, Claregalway Corporate Park, Co. Galway, H91 KXOT
- Phone: +35391773561
- Website: securecom.ie
#11. Clifford Security Alarms Limited
Rounding out the shortlist is a second Limerick option. Clifford Security Alarms Limited is based on Wickham Street in Prior’s-Land, close to the centre of the city.
As a security system installer, the company fits alarms and related equipment for local homes. A central base keeps call-out distances short for anyone living in Limerick itself, which matters over the lifetime of a system that will occasionally need servicing.
Two Limerick installers on one shortlist is deliberate. It lets you compare two local quotes side by side, which is the easiest way to sanity-check what you are being offered. If you are in Limerick, get both names on your list.
- Address: 16 Wickham St, Prior’s-Land, Limerick, V94 PY51

What should you look for in a home security system?
Start with the core components: a control panel, door and window contacts, motion sensors and a siren. Most modern systems are wireless, which makes them quicker to fit and easier to extend later. Decide early whether you want cameras or a video doorbell included, because fitting everything in one visit is usually simpler than adding pieces one at a time.
The bigger decision is monitoring. A self-monitored system sends alerts to your phone and has no monthly fee; a monitored system is watched by an alarm receiving centre that follows an agreed response plan when it triggers. Monitoring costs more each month, but it suits people who travel often or who would not see an alert in time to act on it.
Do security installers need a licence in Ireland?
Yes. In Ireland, companies that install and maintain intruder alarms and CCTV systems must hold a licence from the Private Security Authority (PSA). The PSA sets standards for the private security industry and keeps a public register, so you can check a company’s licence status before you sign anything.
Ask for the licence details early in the conversation and verify them on the register yourself. It is also worth asking what standards the installation will meet and whether you will receive documentation for your insurer. Some insurers ask for a licensed installer before they will factor an alarm into your premium.
What should you ask before you sign?
Get at least two or three written quotes and make sure each one itemises equipment, installation and any ongoing monitoring fees. Ask who owns the equipment at the end of the contract, because some deals bundle the hardware into a longer monitoring agreement and that changes the real cost.
A few more questions are worth asking every company you speak to. How long is the contract, and what does it cost to exit early? What happens if the alarm develops a fault, who do you call, and what does a call-out cost? Can the system be expanded later if you extend the house or add a garden office?
Frequently Asked Questions
How much does a home security system cost in Ireland?
It depends on the size of your house and the equipment you choose. A basic wireless alarm will cost less than a full system with cameras, extra sensors and monitoring, and monitored systems add a monthly fee on top. The only reliable way to compare is to get two or three itemised quotes for the same specification and read carefully what each one includes.
Are house alarms worth it in Ireland?
For most households, yes. A visible alarm box makes your home a harder target than a house without one, and modern systems let you check in from your phone when you are away. Some insurers also offer a discount for a properly installed alarm, so ask yours before you buy. For many people the peace of mind alone justifies the cost.
Is it better to get a monitored alarm or self-monitored?
Self-monitored systems send alerts to your phone and cost nothing per month, but you have to see the alert and act on it yourself. Monitored systems are watched around the clock by an alarm receiving centre that follows an agreed response plan. That suits people who travel often or switch their phone off at night. Weigh the monthly fee against how often the house is empty.
Can I install a home security system myself?
You can. DIY wireless kits are widely sold and a confident DIYer can fit one in an afternoon. The trade-offs are placement and paperwork: a professional installer will position sensors to reduce false alarms, and a professionally fitted system is easier to evidence if an insurer ever asks about it. For a large house or a monitored setup, professional installation is the safer route.
How do I check if a security company is legitimate in Ireland?
Ask for the company’s Private Security Authority licence and check it against the PSA’s public register, which lists licensed electronic security contractors. Beyond that, look for a proper registered address, written quotes on headed paper and clear contract terms. Be cautious of anyone who will only deal in cash or pressures you to sign on the doorstep.
