Commercial security is fundamentally different from residential security. Businesses face unique threats—theft, break-ins, employee safety, property liability—and need security systems designed for commercial demands. This comprehensive guide covers everything Auckland business owners need to know about commercial alarm systems.
At Garrison Alarms, we’ve installed and managed security systems in Auckland businesses for over 35 years. We understand commercial security requirements, compliance needs, and what actually works in real-world business environments.
Why Commercial Security Is Different
Higher Asset Value
Businesses typically have higher-value inventory, equipment, and fixtures requiring protection. Residential systems aren’t designed for this level of coverage.
Multiple Entry Points
Commercial properties have more access points: front entrances, back entrances, loading docks, roof access, multiple floor levels.
Extended Access Requirements
Employees, contractors, delivery personnel, and visitors need controlled access at different times.
Liability Considerations
Businesses have duty of care to employees and customers. Security systems document events and provide evidence in liability claims.
Insurance Requirements
Many insurers require specific security features for commercial policies. Some require monitored alarms for acceptable premiums.
Operational Continuity
System failure causes lost business time and revenue, not just inconvenience.
Compliance Obligations
Businesses may need to meet specific security standards or regulatory requirements depending on industry.

FAQ: Commercial Alarm Systems Auckland
Do I need professional monitoring for my commercial alarm?
Yes, unless you can respond to alarms yourself. Professional monitoring provides emergency dispatch and insurance compliance.
Can I use a residential system for my small office?
Not recommended. Residential systems lack features needed for commercial (user codes, access control, enterprise-grade reliability). Commercial systems justified even for small spaces.
How much does professional monitoring cost?
$40–$80/month for commercial systems. Usually pays for itself through insurance discounts.
What’s the difference between commercial and residential systems?
Commercial systems have user management, access control, enterprise support, larger zone capacity, better reliability, and professional-grade components. Designed for business demands.
Can I expand my commercial system later?
Yes. Commercial systems are highly scalable. Adding zones, cameras, or access points is straightforward.
What if my business relocates?
System can be moved to new location. Some equipment is portable; rewiring needed at new location.
Do I need cameras integrated with alarm?
Highly recommended. When alarm triggers, camera automatically records. Creates evidence of incident.
How often should commercial systems be serviced?
Quarterly professional servicing recommended (vs. annual for residential). More critical for business continuity.
Can I use a security guard instead of alarm system?
Guards supplement but don’t replace systems. Electronic systems provide evidence, documentation, and 24/7 presence even when guards aren’t present.
What’s the difference between a panic button and regular alarm?
Panic buttons send silent alarm (no siren) and directly alert monitoring center. Used for active threats (robbery, assault) where you need police response but don’t want to escalate situation.
