Security Cameras Where There's No Mobile Coverage

You've got a remote compound, a camera quote and a phone showing no bars at the gate. A security camera with no mobile coverage will still record, but it can't tell anyone what it's seeing. On a civil corridor or a mine lease, that gap is the difference between stopping a theft and finding out about it on Monday.

Here's how to test the signal properly, why boosters rarely fix the problem, and when to pay for satellite or settle for recording on board.

How do you check mobile coverage at a site?

Start with the carrier maps, then go and stand on the spot. Under ACMA's coverage map rules, Telstra, Optus and TPG had to publish 4G and 5G maps by 30 June 2026 using the same four coverage levels: good, moderate, basic and no coverage.

Treat a map as a shortlist, though. The maps are predictive modelling, not measured results, and they show likely outdoor coverage at ground level. "Basic" still means occasional disruptions, which is fine for a text and poor for a live video feed.

So run a field test before anyone quotes:

1. Test every camera position. Signal in the site office tells you nothing about the far fence.
2. Test each network. Take a phone or SIM on every carrier you'd consider.
3. Check upload speed. Cameras push video out, so a healthy download figure can hide a weak upload.
4. Test at different times. Telstra says performance varies with location, environment and network load. Include after dark, when the camera matters most.
5. Retest as the site changes. Stockpiles, sheds and earthworks can block a signal that worked in week one.

Do mobile boosters work for site cameras?

Mostly no, and some are illegal. ACMA says it's illegal to own, use or supply a mobile phone booster in Australia. A repeater is a separate device, but it needs your carrier's approval, and only a limited range is authorised. Online bargains may not be legitimate, so check with the carrier first.

The bigger problem is simpler. A repeater strengthens a signal that already exists. Telstra's terms for its approved repeater warn that outside the coverage area, service can fail for lack of signal.

An approved repeater or a passive external antenna mounted high can help at the edge of coverage, where the signal is weak but steady. Rerun the field test with it fitted before you commit, and count any repeater as another load on a solar battery. In a true dead spot, there's nothing to work with.

When does satellite make sense for site cameras?

When the field test fails at the positions that matter. The Siteguard Starlink Tower combines surveillance with satellite connectivity for remote locations without 3G or 4G coverage. Starlink Connectivity supports live video streaming, remote camera access and real-time alerts, and it's fully integrated with all Siteguard camera systems and the Siteguard Foreman dashboard. Our team handles the full setup.

Two checks come first. Starlink needs a clear view of the sky to stay connected as satellites move overhead, so look up before you pick a position. It also costs power: Starlink's Standard kit specification sheet lists an average draw of 75 to 100 W. Your solar security cameras need solar and battery sized for the dish, not a small panel with a dish bolted on.

If mobile coverage is there but shaky, our guide to 4G or Starlink for site cameras covers that decision. The same setup suits remote mining sites, where power, internet and people on site are all limited.

Security camera, no mobile coverage: which setup fits?

Let the field test pick the connection, then match it to the risk.

Recording locally vs live alerts: what changes?

On-board recording gives you evidence. Siteguard's Single Cam lists 24/7 recording and 30-day storage, and footage records to the unit, so a dropout doesn't stop it. Without a link, though, nobody hears about an intrusion until someone checks the footage, often days later. If the unit itself gets damaged or taken, footage held only on board can go with it.

Live alerts give you a chance to act. With Control Room Monitoring, Siteguard's Australian-based operators verify every alarm, then issue audio warnings, activate the siren or escalate to the relevant authorities. None of that can happen on a camera the control room can't reach.

So the choice comes down to what's on site. Fuel, cable and plant justify a live connection. A low-value area you can check every week may not. Most jobs want both: live alerts for response and local storage as the backstop when the link drops. Our guide to remote site security covers how the pieces fit together.
