Detailed diagrams, cable guidance and step-by-step instructions for Australian installations.
Australia's practical wiring diagram resource

Find the right wiring diagram, cable type, checklist or fault guide.

Wiring Diagram Australia is built for people planning CCTV, alarms, intercoms, access control, PoE, gate, solar and low-voltage projects. Start with a diagram, use a template, check the glossary, or diagnose a fault.

Learn the concepts quickly

Some visitors do not need a full project pack first — they need a simple visual explanation. Start here, then move into diagrams and tools.

Power vs data vs relay

Understand the basic connection types you will see across CCTV, intercoms and access control.

Electric strike vs maglock

Understand the most common lock choices before planning a door release system.

PoE switch vs NVR PoE ports

Understand the simplest big CCTV design choice first.
