Can wireless cameras work without Wi-Fi?

Most Wi-Fi cameras require a stable internet connection to upload footage and send alerts. Some (like Eufy with HomeBase) can record locally and continue recording without internet, but you won't get alerts on your phone until the connection is restored. Cellular cameras exist but are expensive and rare for home use in NZ.

How far can a PoE cable run?

Standard PoE ethernet cables can reliably run up to 100 metres (330 feet) before signal degradation. For longer runs, you can use a PoE extender. This is typically more than enough for residential installations.

Do wireless cameras work in rural areas with slow internet?

This depends on the camera and your internet connection. Basic motion alerts work on slower connections, but streaming HD live video requires at least 5–10Mbps upload per camera. In rural areas with satellite or wireless broadband, latency can also affect live view. Battery or solar cameras with local storage often work better in rural situations.

Is it hard to install a PoE camera system myself?

Running ethernet cables through walls and ceilings is more involved than simply mounting a Wi-Fi camera. If you're comfortable with basic DIY (drilling, routing cables, using a fish tape), a small PoE system is achievable. For a professional finish or larger systems, Get Secure can install and configure everything for you.

If you've started shopping for security cameras, you've probably noticed two main camps: plug-in or battery wireless cameras, and wired cameras that connect via ethernet cable. Each has genuine advantages — and the right choice depends on your property, budget, and how much you care about reliability.

Wireless security cameras

"Wireless" usually means one of two things:

Battery-powered Wi-Fi cameras — no power cable, no ethernet. The camera runs on a rechargeable battery and connects to your home Wi-Fi.
Plug-in Wi-Fi cameras — plugged into a nearby power outlet, but still using Wi-Fi for video transmission.

Both types are easy to install. You mount the camera, connect it to Wi-Fi via the app, and you're done. No electrician. No cable runs through walls.

Where wireless cameras work well

Apartments and rentals where permanent cable runs aren't possible
Cameras in locations without a nearby ethernet run
Renters who need to take cameras with them when they move
1–3 camera setups where simplicity is the priority
Indoor cameras

The real limitations of wireless cameras

Wi-Fi cameras have a legitimate Achilles heel that most buyers discover after purchase: motion wake-up delay.

Battery cameras sleep between events to conserve power. When motion is detected, there's a 1–3 second delay before recording actually begins. This means you can miss the beginning of an event — sometimes the most important part.

For a driveway camera capturing licence plates of a vehicle that approached your property, this matters a lot. For a camera checking if a package was delivered, it matters less.

Other wireless limitations:

Wi-Fi dead spots. If your camera is at the far end of your property, signal strength may not be sufficient for reliable video.
Interference. Neighbouring Wi-Fi networks, cordless phones, and other devices can cause dropouts.
Battery maintenance. Battery cameras need recharging every few months. Solar panels help but aren't always reliable in shadier NZ locations.

Wired security cameras (PoE)

PoE stands for Power over Ethernet. PoE cameras connect to your home network via a single ethernet cable that simultaneously carries both data (video) and power. No separate power outlet needed.

The ethernet cables run to a PoE switch or directly to a Network Video Recorder (NVR), which stores footage locally and powers all cameras.

Where wired cameras excel

24/7 continuous recording. PoE cameras record every second — there's no wake-up delay, no missed footage.
Reliability. Ethernet is fundamentally more stable than Wi-Fi. No interference, no signal drops, no buffer zones.
Evidence quality. For driveway cameras where licence plate capture matters, 24/7 wired recording is far more reliable than motion-triggered Wi-Fi cameras.
No subscription needed. An NVR records everything locally with no ongoing cloud costs.
Scalability. A single NVR can handle 8–16 cameras with centralised management and no extra subscriptions.

💡

When to go wired: If you want full-property coverage with 5+ cameras, continuous 24/7 recording, or evidence-grade driveway footage, a PoE/NVR system is almost always the better long-term choice — despite the higher upfront cost.

PoE limitations

Installation complexity. Running ethernet cable requires drilling, routing through walls and ceilings. More work than Wi-Fi cameras.
Upfront cost. The NVR, cables, and professional installation (if needed) make this the most expensive option upfront.
Fixed locations. Once cables are run, relocating cameras is more involved.

The hybrid approach

Many NZ homeowners end up with a mix. They run PoE cables to high-priority locations — the driveway, front door, main entrance — where evidence quality and 24/7 recording matter. Then they use battery or plug-in Wi-Fi cameras for secondary spots like the back deck or side gate where perfect reliability is less critical.

This gives you the best of both worlds without cabling the entire property.
