What is PoE (Power over Ethernet)?
Power over Ethernet delivers electrical power and data over the same network cable, letting devices like wireless access points, IP phones, CCTV cameras and door controllers run without separate power outlets. PoE switches and injectors supply the power centrally.
Why PoE matters for Australian businesses
Your network infrastructure is the foundation of your entire IT environment. Poorly designed or outdated infrastructure leads to slow performance, security vulnerabilities, and costly downtime. As businesses adopt hybrid work, cloud services, and IoT devices, a modern, well-managed network is more important than ever.
For small and medium businesses in particular, PoE can make a real difference in maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current setup or planning improvements, understanding the role of PoE in your broader IT strategy will help you have more informed conversations with your IT provider and make better decisions for your business.

Frequently Asked Questions
What is Power over Ethernet?
PoE runs power and data down a single network cable, so devices like access points, IP phones and cameras need no nearby power point.
What devices use PoE?
Wireless access points, VoIP handsets, security cameras, intercoms, access control readers and digital signage are the most common.
Why does PoE matter for reliability?
Because PoE devices draw power from the switch, putting the switch on a UPS keeps phones, Wi-Fi and cameras alive through short power interruptions.
