CCTV, Intruder Alarm, Fire Alarm, Maintenance & Monitoring Services - M4S SYSTEMS

Skip menu
End-to-end electronic security systems across Ireland
THETA4SECURITY LIMITED – M4S SYSTEMS delivers CCTV, intruder and fire alarms, and ongoing maintenance and monitoring for homes, businesses and industrial sites. From initial security risk assessment and system design through to installation and 24/7 support, we provide a single point of contact for your life safety and security systems.
Our CCTV solutions range from compact HD systems for homes and small shops to multi-site IP camera networks for offices, warehouses and industrial facilities. We design systems around how you actually use your sites – from clear identification of faces and number plates to wide-area overview coverage.

Typical components include fixed and varifocal cameras, NVRs with secure storage, remote access for mobile and desktop, and optional video analytics such as line-crossing and intrusion detection. All systems are installed by certified engineers and configured to balance image quality, bandwidth and storage needs.

We start with a security risk assessment and site survey to understand blind spots, lighting conditions and critical assets before we recommend cameras, locations and recording policies.

Popular CCTV applications:
- Residential properties and apartment blocks
- Retail units and forecourts
- Office buildings and business parks
- Warehouses, yards and industrial sites

Well-designed CCTV not only deters crime but also provides high-quality recorded evidence when incidents occur. For deeper guidance, visit our CCTV & Surveillance articles on the Blog.

Next step: book a site survey so we can design a CCTV system that fits your premises and budget.

We design and install graded intruder alarm systems for residential, commercial and industrial premises, from small offices to complex multi-building sites. Depending on the building fabric and usage, we use a mix of wired, wireless and hybrid technologies to achieve reliable detection and future flexibility.

Systems typically include perimeter protection (door and window contacts, shutter contacts and beam detectors), internal motion detection (PIR and dual-technology sensors), control panels, keypads, remote fobs and mobile app access. Where required, alarms can be integrated with CCTV and professional monitoring to enable visual verification and faster response.

For commercial clients, we work to relevant alarm grading and signalling requirements, and can liaise with insurers to ensure systems meet policy conditions. For homeowners, we focus on practical day-to-day use, minimising false alarms while maintaining strong protection when you are home or away.

Typical intruder alarm features:
- Zoned arming for different areas of the premises
- Push notifications and event logs via mobile app
- Integration with CCTV for alarm verification
- Connection to 24/7 alarm monitoring where required

We will talk you through the options and recommend an alarm configuration that matches your risk profile, operations and budget.
Fire detection and alarm systems are critical life safety assets. We design, install and maintain systems using appropriate detection technologies for each environment – including optical smoke detectors, heat detectors, multi-sensor devices and beam detection for larger spaces.

Our solutions can range from conventional systems for smaller premises to addressable fire alarm systems for larger or more complex buildings, with clear zone indication, cause-and-effect programming and integration with building services where required.

Typical fire alarm components:
- Fire alarm control panel and power supplies
- Manual call points and sounders/beacons
- Smoke, heat and multi-sensor detectors
- Interfaces to lifts, doors and other building systems

We work to applicable fire safety standards and good practice, and we can coordinate with your fire safety consultant, building management and local fire authority as needed.

Our team can also help you plan testing, logbook management and staff training so that your system is more than just a panel on the wall – it is a maintained, documented and trusted part of your safety strategy.
Security and life safety systems must work first time, every time. Our planned preventative maintenance (PPM) programmes help keep your CCTV, intruder and fire alarm systems operating reliably and in line with manufacturer guidance.

During a maintenance visit we typically:
- Inspect and test key devices and field wiring
- Check cameras, lenses, IR performance and image quality
- Verify alarm signalling paths and battery health
- Review logs for faults, tamper events and false alarms
- Apply approved firmware and configuration updates

For many clients we also provide 24/7 alarm and CCTV monitoring. When an alarm is triggered, operators can verify events and follow agreed response procedures, helping to reduce false alarms and support quicker intervention.

Our maintenance and monitoring services are tailored to each site, from single buildings to multi-location portfolios. You benefit from faster response times, 24/7 support, and a team that already knows your systems.

For more insight into keeping systems reliable, explore our Security Guides and Remote Monitoring articles on the Blog, or contact us to discuss a maintenance plan for your existing systems.
QuestionAnswer
How do you design a security system for my property?We start with a conversation about your risks, operations and any existing systems, followed by a site survey where needed. We then design CCTV, intruder and fire alarm solutions that suit how you use the building, any compliance requirements and your budget.
How long does installation usually take?Smaller residential or retail systems can often be installed in a day or two. Larger commercial, industrial or multi-building projects may take several days or be phased to minimise disruption. We will confirm a programme before work begins.
Can I access my CCTV and alarms remotely?Yes. Most modern systems support secure remote access via apps or web portals. We configure this for you, including user permissions, and provide a short handover so you are comfortable using the system.
Do you offer warranties and support?Yes. Equipment is supplied with manufacturer warranties and we provide after-sales support. Many clients choose a maintenance plan which includes scheduled visits, priority fault response and access to 24/7 support.
Is monitoring mandatory for every system?No. Some clients choose local-only alarms, while others require professional 24/7 monitoring for insurance or operational reasons. We will explain the options and recommend an approach that fits your risk profile.
Use these frequently asked questions as a starting point when planning CCTV, intruder or fire alarm systems for your property. Every building is different, so we tailor our designs to your layout, risks and operational needs.

If you have more detailed questions, or would like us to review an existing system, please get in touch and we will be happy to help.
