We started NineTech Systems because too many Sydney homes have poorly installed security systems — cheap cameras, messy wiring, and apps that don't work. We believe every home deserves better.
We saw the same problems coming up over and over — cameras that couldn't record at night, alarms that false-triggered every other day, WiFi that dropped out the moment you walked upstairs, and intercoms no one could figure out how to use.
The root cause was almost always the same: cheap equipment, rushed installs, and no thought put into how the pieces fit together.
NineTech Systems exists to fix that. We use quality brands like Hikvision, Dahua, Bosch, Ajax and Ubiquiti — properly designed, properly installed, properly documented. Every system we build is one we'd happily put in our own home.
These aren't marketing slogans. They're the rules we install by.
Cameras, recorders, alarm panels — you own the hardware. No cloud-only products you lose access to when we're gone. Recordings stay on-site, on your equipment.
PoE-powered cameras. Proper cabling. UPS backups. Lightning protection. Rack-mounted NVRs where appropriate. The details that matter on big projects matter on small ones too.
Written, itemised quotes before any work starts. If the scope changes, we quote again. No surprise invoices, no day-rate blowouts, no "while we're here" upsells.
After handover, you get a PDF with your system diagram, IP addresses, passwords, app logins and how-to guides. If you ever call another installer, they'll have everything they need.
Sometimes the answer is a $300 doorbell, not a $3000 intercom. We recommend what your property actually needs — and tell you when something cheaper will do the job.
After install, you can still call us. Password reset, app update, new device to add, camera moved — real support from the person who installed it, not an overseas call centre.
We only install proven products from manufacturers with proper Australian warranty and support networks.
