When overseeing multiple highways or traffic management projects, site security must be a top risk concern. Criminals target roadwork compounds actively, with equipment, material and cable theft costing UK contractors millions of pounds annually.
Operational directors have the demanding responsibility of protecting plant, materials and crews everywhere they work to limit the cost of security breaches. The challenge is made harder by tight budgets, stretched teams and stakeholders who demand detailed explanations whenever a serious safety or security incident occurs.
Traditional security guards and deployable CCTV towers are both widely employed on traffic and highway schemes. Depending on the location, both have their place, so it's useful to weigh them against each other, understanding the coverage and deployment benefits each offers as well as cost factors.
Our article breaks down how the 2 approaches compare across a multi-site operation, and explains how rapidly deployable CCTV systems, backed by centralised monitoring, often deliver stronger long-term value.
Why is Consistent Security Across Multiple Locations a Challenge?
Securing multiple highways or traffic projects to the same standard is an ongoing challenge for contractor directors. This is especially true when guarding depends on on-site security personnel.
Security guards can't always be in the "right place at the right time", especially in complex traffic management environments, and they're also entitled to breaks. This creates blind spots that opportunistic thieves and Organised Crime Groups (OCGs) are quick to exploit.
A manned guarding approach can introduce human error and limitations, meaning fatigue, distraction, apathy and poor training can all influence how vigilantly your compound is protected. Two sites can be secured to very different standards simply because they're staffed by different personnel.
The consequences of a perimeter breach can hit your programme hard. Stolen or damaged assets can cause delays, eating into margins. On top of that, project owners can be held liable if intruders are injured in a traffic management or work zone, even though they trespassed illegally.
Meanwhile, inconsistent incident reporting damages investigations and recovery efforts, and a lack of objective evidence compromises claim handling. For example, insurance claims are often denied because the business lacks the evidence to prove its security controls meet policy requirements.
4 Factors to Evaluate When Comparing Security Guards vs CCTV for Highways Traffic Projects
Below we highlight 4 critical considerations when comparing guard patrols with CCTV systems for highways and traffic management locations.
1. Visibility and coverage
On-site guards typically patrol, moving between compounds, checking access points and walking the perimeter on a schedule. To monitor a major infrastructure zone without leaving coverage gaps requires a sizeable, highly disciplined, trained and continually patrolling crew. This large guard contingent, of course, adds real cost to your budget.
A CCTV tower provides continuous oversight, day and night. High-quality PTZ (pan-tilt-zoom) cameras offer low-light and night-vision recording, capturing detail that human eyesight frequently misses.
Strategically positioned towers can actively monitor a wide area, providing visibility across every corner of a large work zone. Traffic Management Towers are designed for the practicalities of both busy urban and remote traffic schemes, with the height (around 6 metres) to capture large and high-risk zones and surrounding traffic well.
Coverage advantages of CCTV
Well-positioned CCTV supported by a cloud-based platform provides 24/7 visibility across all monitored locations, without a shift change or lapse in concentration. By their visible presence, these towers and high-definition cameras also act as a strong deterrent against criminal activity.
2. Deployment speed and scalability
Introducing guard patrols or a security contract into your programme entails vetting, recruiting, onboarding and scheduling. This process takes time, so arranging or scaling coverage at short notice isn't always possible.
The vetting exercise alone (whether of individuals or guarding contractors) can't be shortcutted, since the quality and training of personnel directly impact the effectiveness of your protection. Sometimes, traffic and work conditions are so hazardous that you must limit your workforce for health and safety reasons.
Portable CCTV towers, by contrast, are designed for rapid, flexible deployment, even in work zones with above-average dangers such as busy rolling traffic operations. Mobile setups can be in place and operational within hours to monitor the required safety measures (restricted zone control, worker protection, traffic movement, managed lane closures, etc.).
This is invaluable when schemes change location regularly, and re-negotiating guarding or traffic controller arrangements each time is not practical.
Scaling coverage is also straightforward. Additional units can be deployed as you add new locations, and brought onto the same central platform within hours, not days.
Deployment advantages of CCTV
Highways projects and temporary traffic management schemes require flexible oversight that can respond quickly to shifting priorities and locations. Guard‑only models don't always offer this adaptability. As mentioned, adding personnel can take time, and guards on one traffic project may not accept a transfer to a new location because it's too far to travel.
CCTV coverage can be rapidly deployed and expanded, ensuring you always have visibility as your scheme develops or new traffic priorities arise. This model also lets you accurately match deployment costs to actual needs.
3. Evidence collection
Traditional security reporting depends on what was seen, remembered and written down, often by hand, and frequently after the fact. Relying solely on this approach leaves contractors short of vital evidence when it matters most.
When clients ask hard questions about an incident, or your contracted security provider disputes events or insurers question a claim, you need verifiable records to defend your position. Without it, you could face reputational damage, unplanned liabilities and costly insurance disputes.
Modern CCTV monitoring platforms capture and generate the objective evidence you need to reduce commercial risk following incidents (theft, vandalism, trespassing, sabotage, etc.)
Central cloud-based platforms store timestamped video footage and reports documenting what happened, when and how. This information lives in one place, where you can access it with a few clicks to address stakeholder questions, insurance and other claims.
Evidence-gathering advantages of CCTV
The consistent, objective evidence retained by modern CCTV platforms is a great improvement compared to inconsistent, subjective, often delayed human reports and paper logs.
4. Costs and value
A security guard's wage (£14 - £30+ hourly) may be cheaper than CCTV rental, but are physical foot patrols always the most cost-effective security system? Understanding the true cost of protecting your highways or traffic management project requires a more detailed analysis.
When employing manned guards at multiple locations, you carry the cost of:
- Ongoing staffing across every shift, every site, throughout the duration of all contracts.
- Management and admin overheads. These can include scheduling, supervision, benefits and headaches such as absences and disciplinary issues.
- Variable performance, which can translate to higher incident rates, disruptions, claims and time-consuming investigations.
- Weak or inconsistent evidence when something goes wrong.
With deployable CCTV systems, the cost structure is different:
- A predictable rental cost, where you only pay for the coverage you need.
- Quick, straightforward scaling, which allows you to match costs precisely to usage.
- Minimal management and admin. Installation, live monitoring, maintenance and support are usually taken care of by the supplier.
- No recruitment, personal vetting, absence cover or disciplinary problems to manage.
- Greater visibility into risks enables you to act preventively to limit accident and injury costs.
- Clear, timestamped, retrievable evidence for every incident, making dispute resolution easier and less expensive.
The value advantages of CCTV
For managing several workplaces over a few months, the cost of CCTV monitoring tends to compare favourably with the all-inclusive expense of traditional guarding. Indeed, it's been shown that over time, CCTV can save up to 88% on security costs compared to guards.
CCTV platforms not only reduce wages and overtime costs associated with security personnel but can also reduce monitoring team headcount.
