Protection that fits your everyday routine
Set the alarm as you leave, protect suitable areas while you are inside and manage access for the people who use the building. We recommend the equipment and configuration for your property.
Easy to set and unset
Keypads, fobs and supported apps give you practical ways to use the alarm. We demonstrate the controls at handover.
Detection in the right places
We assess entrances, rooms and how the premises are used, then position and configure the selected detectors.
A clear route after an activation
We explain local sounders, app notifications and monitored response, including what each option needs to work.
Wired, wireless and hybrid systems
Wired devices connect by cable. Wireless devices use radio links and need the appropriate battery and signal checks. Hybrid systems combine the two. We assess cabling, radio coverage, existing equipment and required system grade before recommending an approach.
App-connected control
App functions depend on the selected equipment, connectivity and permissions. An app does not by itself provide an operator response.
Room to suit a larger site
Separately controlled areas and supported integrations can help the system fit a larger building or several premises. We confirm what is possible in the proposed design.
Support beyond the sounder
Monitoring provides a defined way to handle an alarm signal. We explain the options and agree the response arrangements for your premises.
Sounder-led response
A sounder alerts people nearby. App notifications may also be available with suitable equipment and connectivity. These options rely on someone receiving the alert and taking action.
Monitored response
Intruder alarm signals go to our monitoring partner’s NSI Gold certified Alarm Receiving Centre (ARC), which follows the agreed response plan. This can include keyholder contact and, for eligible registered systems, a police response request.

The installation engineer was polite and friendly and liaised with us during the installation regarding the siting of the equipment.

Installation standards and insurance requirements
Advanced Overwatch is SSAIB certificated (NIRE127) specifically for Intruder Alarm Systems, Visual Surveillance Systems (VSS) and Access Control Systems.
We review any alarm requirements in your insurance documentation as part of the specification. The insurer determines what the policy requires; we explain the proposed system, grade and monitoring arrangements.
The proposal and handover identify the applicable system standards and agreed services.
- Intruder alarm design and installation to the applicable BS EN 50131 requirements through PD 6662.
- Commissioning documentation for the installed system.
- Maintenance and monitoring scope agreed for the premises.
- Police response arrangements only where the system meets the current eligibility and registration requirements.
From survey to a system you can use
We handle the design, installation and testing, then show you the controls. Maintenance is available to look after the system afterwards.
Survey and proposal
We assess the property and provide a written specification and quotation.
Installation and testing
We fit the equipment, configure the system and test the agreed functions.
Handover and care
We demonstrate the controls and explain the available maintenance and support.
Care for the alarm you rely on
- Inspect
- Detectors, sounders, power supplies and relevant signalling paths.
- Service
- Battery and component checks, with applicable software or firmware work.
- Record
- Service findings and the work completed for your system.
- Support
- Fault reporting and response arrangements defined in the service agreement.
We agree servicing and support for your system, with clear arrangements for reporting a fault. Explore maintenance or get support for an existing system.

Intruder alarm manufacturers we install
Advanced Overwatch is a certified partner and installer for Ajax and Orisec, our preferred intruder alarm partners.
We design and install intruder alarm systems from these manufacturers, chosen to suit the property rather than one brand bought in bulk.
Burglar alarm installation questions
How much does an alarm system cost for a business?
The price depends on the premises, detection, cabling, system grade and any monitoring or app services. We provide a written quotation after a free survey, setting out the equipment, installation and proposed ongoing services.
Do burglars avoid homes with alarms?
An alarm can be part of a visible security arrangement, alongside suitable locks and lighting. It cannot guarantee that a break-in will not happen. Good design, correct use and maintenance help the system do the job it was installed for.
Is there a local alarm company near me in Northern Ireland?
Advanced Overwatch installs and maintains intruder alarms across Northern Ireland. We cover homes, businesses and public sector premises, including Belfast, Derry / Londonderry, Newry and surrounding towns and rural areas.
What should I look for when choosing an intruder alarm installer in Northern Ireland?
The proposed design should suit the property, applicable standards and any insurance requirements. Certification, commissioning documentation, user training and written maintenance and monitoring terms help make the offer clear. Our credentials and scope can be checked on the certification page.
What is the difference between a wired and wireless intruder alarm?
Wired devices communicate through cables; wireless devices use radio links. Hybrid systems use both. The suitable approach depends on cable access, radio coverage, existing equipment and the required system grade. We assess these at the survey, including battery and ongoing maintenance requirements.
Is a monitored intruder alarm system worth the cost?
Monitoring adds an agreed response process when an alarm signal is received. It can suit properties that are empty, businesses with particular risks or systems required by an insurer. We explain the recurring service and response arrangements so the proposal is clear.
What is the difference between grade 2 and grade 3 intruder alarms?
System grades describe different risk and performance requirements under the EN 50131 series. The appropriate grade depends on the premises, risk assessment and any insurer requirements. We recommend the grade as part of the system design.
Do I need a police response alarm in Northern Ireland?
That depends on the risk and any insurance requirement. Police response is not automatic: the system must meet the applicable standards, registration and eligibility rules. We discuss the available arrangements for your premises, without promising attendance or a response time on behalf of the police.
