Commercial Alarm Systems Sydney: detect intruders and protect your premises
Intruder alarm systems for Sydney businesses, designed and installed by licensed NSW technicians. Sensors, mobile control and back-to-base ready signalling for CBD offices, warehouses and multi-tenant sites across Greater Sydney.
Stop after-hours break-ins before they cost you
From CBD office towers to the warehouses strung out along the Western Sydney logistics corridor, Sydney businesses share the same risk: after-hours intrusion, stock loss and the disruption of reopening a site that has been hit. A commercial alarm system detects intrusion early, sounds a deterrent and signals the right people fast.
We design and install intruder alarms for Sydney offices, warehouses, retail tenancies and multi-site operators, whether you run a Parramatta head office, a Macquarie Park campus or a multi-tenant building in the CBD. Choose wired, wireless or hybrid sensor layouts, integrate the alarm with your CCTV, access control and building management, and add optional 24/7 back-to-base monitoring with dual-path reporting over NBN and 4G/5G.
As a licensed NSW security provider with our HQ in Granville, we handle the strata and owners-corporation side too: clear placement and cabling documentation so committee sign-off for common-area devices is straightforward. We confirm a fixed-scope price after a quick site assessment, with no obligation.

Protect your business from anywhere
Mobile control
Arm, disarm and get instant alerts from your phone, with separate user codes for staff and contractors.
Dual-path uptime
NBN plus 4G/5G failover keeps reporting alive through outages and line cuts across single or multiple sites.

PIR, dual-tech, reed, glass-break and external beams sized for warehouse aisles, shopfronts and loading docks.
Licensed NSW team
Sydney-based installers under a NSW Master Security Licence for design, install and ongoing support.
Intruder detection built for Sydney commercial sites

Wired, wireless or hybrid
Hard-wire fixed offices and warehouses, use wireless where cabling is hard in heritage CBD buildings or fitted-out tenancies, or combine both.

Sensor coverage that fits
Dual-tech PIRs for high-bay Western Sydney warehouses, reeds on roller doors and fire exits, glass-break on shopfronts and beams across yards.

Back-to-base monitoring
Australian monitoring centres receive events in real time, verify alarms and escalate with your agreed call list and guard or police response.

App control and audit logs
Arm by area or tenancy, review open/close times, receive push alerts and issue temporary codes for cleaners, contractors and deliveries.
Sydney commercial alarms: what shapes the right system
Building type, tenancy mix and licensing all change the install pattern
CBD towers and multi-tenant buildings
Towers and multi-tenant sites need clear area separation so each tenancy arms and reports independently, plus coordination with base-building security and lift or after-hours access. We zone the system around how the building actually operates.
Western Sydney warehousing
Logistics sites through Eastern Creek, Wetherill Park and the M7 corridor need high-bay dual-tech detection, roller-door contacts and yard or perimeter beams, with arming schedules that suit shift work and 24/7 dispatch.
Strata and owners-corporation sign-off
For common-area devices in strata or multi-tenant buildings, the owners corporation usually needs to approve hardware and cabling. We document placement and scope so committee sign-off is straightforward.
Licensed NSW security work
Metwide holds NSW Master Security Licence 000107431 and is a registered ASIAL member, so your alarm is designed and installed by a licensed NSW security provider, with cabling that is ACMA-compliant.
