Search for construction site CCTV and you'll mostly find one answer: hire. Monitored towers, wheeled onto site, rented for the duration. Hire firms dominate the market — and for a specific kind of site they're the right call. But for the majority of UK builds, especially smaller and medium jobs, the maths points the other way, and it's worth doing before you sign a hire agreement.
What each option actually is
Hired CCTV towers are tall, highly visible units, typically with multiple cameras, floodlights and — the key ingredient — a monitoring contract: a control room watches alerts and can challenge intruders through a speaker and call keyholders or police. You pay weekly or monthly for the duration of the job, and pricing is usually quoted per site per week, commonly running to hundreds of pounds a month once monitoring is included.
Bought solar 4G cameras are compact self-contained units — camera, solar panel, battery, SIM — that you own outright, mount on scaffolding, containers or poles, and monitor yourself through an app with person and vehicle alerts. A Solar 360 Mini is £169 one-off with the multi-network SIM and memory card in the box; the running cost is SIM data from £5/month.
The crossover point
The comparison comes down to one calculation: hire is a recurring cost per site; purchase is a one-off cost per camera, amortised across every job it ever watches. A single hired tower's monthly bill can exceed the entire purchase price of a solar 4G camera — which means the crossover point typically arrives within the first couple of months of a job, and every job after that runs on kit you already own. Unbolt the cameras at handover, put them on the next compound, repeat. For a builder running several sites a year, the same maths compounds across the portfolio.
When hiring genuinely wins
Honesty matters here — towers earn their keep when:
- You need professional monitoring and response. If the risk profile justifies a control room challenging intruders at 3am and dispatching a response, that service is the product — and you can't buy it for £169.
- The site is very large or high-value. Major infrastructure jobs with big plant inventories often need layered, monitored security as a contractual requirement.
- Insurance or the principal contractor specifies it. Some contracts mandate monitored CCTV — check before deciding.
When buying wins
- Small and medium sites — housing plots, extensions, barn conversions, groundworks phases — where the job is deterrence plus evidence, not manned response.
- Long jobs. The longer the programme, the more brutal the hire maths becomes.
- Repeat builders. Cameras become site kit, like the fencing and the welfare unit — bought once, redeployed forever, checked from one app across every live job.
- Early phase sites with no power. Solar 4G cameras work from day one of enabling works — no generator, no waiting for the DNO.
The middle path most builders land on
Plenty of sites run a hybrid: owned solar cameras covering the compound, gates and plant rows for the whole programme, with a monitored tower hired only for a high-risk window — the week the M&E kit arrives, or a site with an active travelling-crime problem. You get always-on coverage you own, and pay hire rates only when the risk justifies them.
Do the sums for your own site
Get a hire quote for your programme length, then put it next to the one-off cost of two or three owned cameras plus £5–£10 a month in SIM data — and remember the owned kit still has a job after handover. Our construction site camera guide covers siting, alerts and evidence in detail, and our UK team will tell you honestly if your site is one where a monitored tower is the better answer.
