Construction sites are an easy target: valuable gear, open boundaries, and nobody around once the crew’s gone home. This guide is for builders, site managers and contractors across NSW, covering the main risks, what actually helps, and what it costs to put basic security in place.
Common threats on a site
Sites get targeted because they’re often unoccupied overnight and on weekends, and full of portable, resellable gear. A theft or a bout of vandalism doesn’t just cost you the replacement — it can hold up the next trade, delay the programme, and mean a drawn-out insurance claim on top. The main risks are:
- Tool and equipment theft — hand tools, generators and machinery left on site overnight
- Material theft — copper wiring, steel and other materials that resell easily
- Fuel theft — diesel and fuel stored on site for machinery and generators
- Vandalism — damage to half-finished work or site infrastructure
- Trespass — people wandering onto an active site, which is also a safety risk
- Site office or container break-ins — cash, tools and paperwork kept on site
A camera covering the entrance and the main storage area is usually enough to see who’s come and gone, and gives you something real to hand to police if gear does go missing. The entrance, the material compound and wherever plant and machinery is parked overnight are the spots worth covering first — not every corner of the site needs a camera, just the places someone would actually have to pass through or get to. Many of the same risks apply on a warehouse or industrial site too.
Perimeter and access control
Most sites rely on temporary fencing and hoarding as the first line of defence, with one controlled entry point rather than several gaps around the boundary. Hoarding is usually the better choice where you want to block sightlines into the site; chain-link fencing is faster to put up and easier to move as the site changes shape. Beyond the fence line itself:
- A single entry point — easier to monitor than multiple access tracks
- Key or code management — knowing who can get in and when
- Contractor sign-in — a simple record of who’s on site
- Vehicle access control — managing deliveries and site traffic through the same entry
- Signage at the entrance — letting people know the site is monitored, which also matters for the surveillance rules below
If the site needs intercoms or controlled entry at the gate, see our access control quote form.
CCTV, remote viewing and power
A camera only helps if it’s actually recording and someone can check it. We hire out solar-powered CCTV units built for construction sites that mount to a pole, fence or hoarding and run on solar with a battery — no mains power needed, which matters on a site before connection is even in.
You get app-based access to check footage from your phone. We don’t run a back-to-base monitoring service on these units, so checking in is on you — that’s what keeps the hire straightforward. Units can be repositioned as the site changes, moved from the entrance in the early stages to cover a different risk once the building takes shape. If the site already has a few cameras up and you’re adding alarms or extra coverage, it’s usually simpler to extend what’s there rather than start again. Some sites also pair cameras with mobile patrol visits for an extra physical check, though that’s a separate service to what we provide.
Once the build’s finished and the site needs a permanent system, get a CCTV quote and we’ll fit it out properly — and if it ever needs a check-up, we also do maintenance visits.
Legal compliance for site surveillance in NSW
If you’re running CCTV on a site, a few basics are worth getting right. Under the Workplace Surveillance Act 2005 (NSW), cameras need to be clearly visible, with signage at each entrance, and workers need written notice at least 14 days before surveillance starts — anyone who joins the crew after that needs notice before they start. It’s also good practice to avoid pointing cameras over the boundary into a neighbouring property unless you’ve got good reason to and can justify it — this matters more on a construction site than most places, since workers, delivery drivers and the public all pass through, and a camera aimed at the gate can easily catch footpaths or neighbouring windows if it’s not angled carefully.
None of this is hard to get right, but it’s easy to overlook when you’re focused on getting cameras up quickly. A quick check of camera angles when the unit goes in, and a sign at the entrance, saves a conversation about it later — particularly if the site borders homes or a footpath people walk past every day.
Costs and hire vs buy
Temporary CCTV for a site is usually hired for the length of the job rather than bought outright — it’s solar-powered, goes up without any site power, and comes down again when the job’s done. Hiring also means you’re not left owning gear built for a job site once the project’s finished, and if a unit needs servicing during the hire, that’s on us rather than something you have to organise. A permanent system makes more sense once the site becomes an operating building and the security need doesn’t end with the project.
Either way, cost depends on how many cameras you need, how long they’re on site, and what access looks like for install and pickup. A short job with one or two cameras at the entrance costs a lot less than covering a large site with multiple access points over a long build — so it’s worth getting a quote once you know roughly how long the project will run and how many areas actually need coverage.
How Saint George Group can help
We’re a licensed NSW security installer (NSW master licence ML000111327), working construction sites across NSW — Sydney, Newcastle, Wollongong, the Central Coast and beyond. Tell us how many cameras you need and for how long, and we’ll quote the hire. If you’d also like intercoms or controlled access at the gate, see our access control quote form. Once the project’s finished, we can also fit out and maintain the permanent system that replaces the hire gear.
Quick answers
Do you monitor the cameras for us? No — you get app access to check footage yourself. We don’t run a back-to-base monitoring service on hire units, which keeps the cost down.
Can cameras go up before the site has power? Yes. The hire units are solar-powered with a battery, so they work before mains power is connected.
Do you install gate motors or automatic gates? No, we handle the intercom and access control side — cameras, keypads and entry systems — rather than the gate motor itself.
Can we add more cameras partway through the job? Yes. As the site changes — a new stage, a different access point — units can be added or repositioned to match.
Security on a construction site doesn’t need to be complicated — a camera at the entrance, a controlled gate, and someone actually checking the footage covers most of what goes wrong. Get the basics right early and it’s one less thing to think about as the build moves through its stages.
