How Do 4G Security Cameras Work Without Wi-Fi? An Australian Guide

If you want a camera somewhere your Wi-Fi doesn't reach (a gate, a shed, a block of land, a holiday house) a 4G security camera is usually the simplest answer. But how does a camera work with no Wi-Fi at all? And what does it cost to run? Here's a plain-English guide for Australians.

Quick pick: the HiLink Solar 4G PTZ Camera. A$249, solar powered, 12 months of 4G data included, no Wi-Fi or power point needed.

How a 4G security camera works

A 4G camera has a SIM card inside it, just like your phone. Instead of connecting to your home router, it connects straight to the mobile network (Telstra, Optus or Vodafone towers) and sends video and alerts to an app on your phone over that connection.

That means the camera doesn't care where your router is, or whether the property has NBN at all. If a phone gets usable 4G signal at the spot you want to mount it, the camera can too.

What about power?

Many 4G cameras still need a power point, which defeats the point on a remote spot. A solar 4G camera solves both problems at once: a solar panel charges a built-in battery during the day, and the camera runs on the battery overnight. The HiLink Solar 4G PTZ needs as little as 2–3 hours of direct sun a day to keep running.

4G camera vs Wi-Fi camera

• Wi-Fi camera: cheaper to run, but only works within range of your router, and usually needs a power cable.
• 4G camera: works anywhere with mobile signal, no router or cabling, but uses mobile data.
• Wired PoE camera kit: best picture and continuous recording for the house itself, but needs Cat6 cable run to every camera.

Plenty of properties use a mix: a PoE kit around the house and a 4G camera for anything out of cable or Wi-Fi reach.

How much data does a 4G camera use?

It depends mainly on how often you watch live and how many motion events it records. A camera that mostly sits quietly and sends alerts uses far less than one you live-stream for hours. Good ways to keep data low:

• Use human and vehicle detection so wind, birds and animals don't trigger recordings
• Record to the local SD card and only view clips when something happens
• Watch live when you need to, rather than leaving the stream open

The HiLink Solar 4G PTZ ships with a SIM and 12 months of data included, so there's nothing to set up with a carrier in the first year. After that, any standard Australian 4G data SIM works in the camera's SIM slot.

Before you buy: check the signal

Stand where you plan to mount the camera and check your phone's signal, or look up the spot on your carrier's coverage map. One or two solid bars of 4G is usually enough for alerts and clips. If the signal is weak at ground level, mounting higher on a pole or shed often helps.

Frequently asked questions

Do I need Wi-Fi to set it up?

No. The camera connects over 4G and you set it up from the app on your phone.

Can I watch it from anywhere?

Yes. As long as the camera has 4G signal and your phone has internet, you can view it from anywhere, including overseas.

Does it record if the signal drops?

Yes. It records to a local SD card, so footage is kept even if the connection drops for a while.

Does it work at night?

Yes. The HiLink Solar 4G PTZ has full-colour night vision.
