Wired (PoE) vs Wireless CCTV: Which is Better?

For permanent home or business CCTV, wired PoE is the reliable choice - a single cable carries power and data, with no Wi-Fi dropouts and no batteries to change. Wireless suits renters or spots you can't run a cable to, but it depends on Wi-Fi strength and often needs battery changes.

What PoE means

Power over Ethernet (PoE) sends both power and video down one network cable (Cat5e/Cat6) from the recorder to each camera - up to around 100 metres. One cable per camera, no separate power supplies, no Wi-Fi.

Why wired wins for permanent CCTV

A wired connection is consistent: no interference, no dropped frames when the Wi-Fi is busy, and full-resolution recording around the clock. It's the standard for systems you want to rely on for evidence.

When wireless makes sense

Wireless cameras install in minutes and go where cables can't, which is ideal for renters or temporary use. The trade-offs: they rely on strong Wi-Fi, can drop connection, and battery models need recharging.

Frequently asked questions

Is wired CCTV better than wireless?
For permanent, reliable CCTV, yes - wired PoE avoids Wi-Fi dropouts and batteries and records at full resolution 24/7. Wireless is better for renters or temporary use.

How far can a PoE cable run?
Standard PoE runs up to about 100 metres of network cable from the recorder to the camera. Longer runs need a switch or extender.

Do PoE cameras need a separate power supply?
No - that's the point of PoE. The camera gets its power from the same network cable that carries the video, straight from the PoE NVR.
