Intruder Alarm Installation - Protect Your Business

Our intruder alarms operate reliably in the background, protecting your site when you’re not there. Monitoring continuously, they alert the right people when required, without false activations. That’s why we average just one false alarm every six years, compared with an industry average of one per year.

FAQs

Quick answers to common questions about commercial intruder alarm systems and installation.

We install everything from simple bells-only to sophisticated multi-zone setups with remote monitoring. Wired or wireless, conventional or smart – we recommend what fits your needs and budget.

Over 33 years. We’ve installed thousands of systems across the South East since 1993. Many of our original customers still use systems we installed decades ago – properly installed equipment lasts.

Modern features that add value without complexity. Remote app control, smart home integration, video verification, and intelligent analytics that reduce false alarms. But “advanced” doesn’t mean complicated – everything stays simple to use.

Yes. We hold NSI Gold accreditation – the highest standard in the industry. This means police response eligibility, insurance approval, and guaranteed quality. Every install meets British Standards and insurance requirements.

We work with proven brands like Texecom and Verkada. We choose manufacturers based on reliability, not margins. These systems last longer, need fewer repairs, and have better support when you need parts.

Three reasons: protection, deterrence, and compliance. Alarms protect your assets, deter criminals and meet insurance requirements. Most commercial policies demand professionally installed, maintained alarms. Without them, claims can be rejected.

Absolutely. Every system is designed specifically for your premises. We assess your layout, understand your operations, and create protection that works around your business. No generic packages – just tailored security.

Multiple options: app control on your phone, keyfob operation on-site, or full professional monitoring from our control room. Choose what works for your business. Most clients combine app access with professional monitoring for complete coverage.

Yes. All our installations meet BS EN 50131 and PD 6662 standards. We’re NSI Gold accredited and follow all industry guidelines. Every system we install is designed to give you the best chance of passing a insurance or compliance inspection.

Yes. Regular maintenance keeps systems reliable and compliant. We offer various service packages from annual inspections to comprehensive cover with guaranteed response times. All maintenance is logged in an online portal for compliance proof.

Usually, yes. We assess your current system and identify upgrade options. Sometimes adding smart features or better sensors is enough. Sometimes a new panel modernises everything. We’ll explain what’s possible and what makes sense for you.
