CCTV · Access control · Monitoring
Protecting what matters, from business to home.
Owner-operated and based in Masterton, working across the whole Wellington region — Wellington, the Hutt Valley, Porirua, Kāpiti and the Wairarapa. We design, install and look after CCTV, alarms, access control and 24/7 monitoring for workshops, warehouses, office and apartment buildings, shops, farms, building sites and homes.
Security built around how you live and work
Whether it's a workshop, an office or apartment building, a shop, a farm or your own home, you get a system designed for the way you use the place — not a one-size-fits-all package.
Also looking after schools, clubs and community halls.
What we install and look after in the Wellington region
CCTV Installation
Crystal-clear footage day and night, recorded to a secure NVR with remote viewing on your phone. Clean, tidy installs and camera placement that actually covers risk spots.
Access Control & Gates
Control who gets in (and when) with keypads, cards/fobs and tidy door or gate automation. Proper electric strikes/maglocks, set up to NZ standards.
Alarm Systems
Reliable wired or wireless sensors, simple arming/disarming and app control. We design zones that make sense for how you live and work.
24/7 Alarm Monitoring
24/7 professional monitoring with clear escalation steps — we call you fast, verify the event, and notify the right people.
Security Maintenance & Upgrades
Keep good gear working. We service faults, update firmware and replace only what’s needed — not the whole system.
Building Site Security
Portable solar and battery-powered cameras and alarms that install fast and connect over 4G — no power or fixed internet needed.
