Manned Guarding Vs CCTV: Which Is Better For Your Enhanced Tier Venue?

The landscape of public safety in the UK has undergone a fundamental shift with the introduction of the Terrorism (Protection of Premises) Act 2025, commonly known as Martyn’s Law. For owners and operators of large-scale venues, the stakes have never been higher. If your premises or event expects to host 800 or more people simultaneously, you fall into the Enhanced Tier.
At this level, "basic awareness" is no longer enough. The law demands documented, proportionate, and effective public protection measures. This often leads to a critical debate for facilities managers and security directors: Should you invest in more Manned Guarding, or is a state-of-the-art CCTV system sufficient?
At KGFM Ltd, we believe the answer isn't a simple "either/or." To achieve true compliance and, more importantly, to ensure the safety of the public, you must understand how these two pillars of security function under the new legal framework.
UNDERSTANDING THE ENHANCED TIER REQUIREMENTS
Before comparing tools, we must look at the legal mandate. The Enhanced Tier applies to high-capacity locations such as stadiums, large arenas, major shopping centres, and significant festivals. Unlike the Standard Tier, the Enhanced Tier requires:
- A Detailed Terrorism Risk Assessment: A formal document identifying specific vulnerabilities.
- Documented Public Protection Measures: Tangible steps taken to reduce the risk of an attack and the physical harm it could cause.
- Security Industry Authority (SIA) Submission: Your plans must be ready for inspection by the regulator.
- Monitoring of Premises: You must actively monitor the venue and its immediate vicinity.
The objective is clear: Detect, Deter, and Defend.
THE CASE FOR MANNED GUARDING: THE HUMAN SHIELD

For Enhanced Tier venues, Manned Guarding remains the most effective way to manage movement and provide immediate intervention. A camera can record an incident, but it cannot stop one.
1. DIRECT ACCESS CONTROL AND SCREENING
At an 800+ capacity venue, entry points are high-risk zones. Professionally trained guards are essential for conducting bag searches, person screening, and verifying credentials. Under Martyn’s Law, controlling "the movement of individuals into, out of, and within" the premises is a core requirement. Manned guarding is the only way to physically enforce these perimeters.
2. DYNAMIC THREAT ASSESSMENT
A highly trained guard can spot Hostile Reconnaissance: the subtle behaviours of someone planning an attack: that an algorithm might miss. Our guards at KGFM are trained to the highest SIA Standards at our own dedicated Training Centre, ensuring they have the "soft skills" to engage with the public and the "hard skills" to identify suspicious activity instantly.
3. IMMEDIATE EMERGENCY RESPONSE
In the event of a security breach or a suspected IED, seconds count. Manned guards are the "boots on the ground" who initiate lockdown procedures, guide thousands of people through evacuation routes, and provide real-time intelligence to emergency services.
4. THE KGFM USP: PERSONAL SUPERVISION
We do not just "supply and forget." Every deployment at KGFM is subject to personal supervision at all times. This ensures that guards remain alert, compliant with your site-specific risk assessment, and integrated into your venue's culture.
THE CASE FOR CCTV: THE UNBLINKING EYE

While guards provide the physical response, CCTV Installations and Monitoring provide the visual data necessary for large-scale oversight.
1. CONTINUOUS PERIMETER MONITORING
Martyn’s Law explicitly mentions the "monitoring of the premises and their immediate vicinity." For a large stadium or retail park, it is physically impossible to have a guard every ten metres. CCTV allows a single operator to oversee vast areas, including car parks, loading bays, and street-level approaches, ensuring no blind spots are left for hostile actors.
2. EVIDENCE AND POST-INCIDENT ANALYSIS
Should an incident occur, high-definition footage is vital for the Security Industry Authority and the Police. It allows for the reconstruction of events, identification of suspects, and a thorough review of how security protocols performed under pressure.
3. COST-EFFECTIVE SCALABILITY
Once installed, a CCTV system provides 24/7 coverage at a fixed cost. It serves as a force multiplier, allowing a smaller team of guards to be deployed more strategically based on where the cameras detect the most significant need.
MANNED GUARDING VS CCTV: THE COMPARISON
| Feature | Manned Guarding | CCTV Monitoring |
|---|---|---|
| Response | Immediate Physical Intervention | Observation & Alert Only |
| Deterrence | High (Visible Authority) | Moderate (Signs & Cameras) |
| Search/Screening | Essential for bag/person checks | Cannot perform physical checks |
| Coverage | Limited to guard's line of sight | Wide-angle, 360-degree options |
| Context | Understands human behaviour | Relies on operator interpretation |
| Reliability | Subject to human fatigue | Subject to technical failure |
THE HYBRID APPROACH: THE GOLD STANDARD FOR MARTYN’S LAW

For an Enhanced Tier venue, choosing one over the other is a dangerous compromise. The most robust: and most legally defensible: security strategy is a hybrid approach.
In this model, CCTV acts as the "Detection" layer, spotting anomalies and tracking movements across the entire site. Manned Guarding acts as the "Response" and "Engagement" layer, moving to intercept threats and managing the crowd.

CHECKLIST FOR ENHANCED TIER VENUE MANAGERS
If you are responsible for a venue with 800+ capacity, ask yourself these three questions:
- Can we justify our security mix? If your risk assessment is challenged by the SIA, can you explain why you chose your specific ratio of cameras to guards?
- Is our staff training up to date? Martyn’s Law requires terrorism-specific awareness. General security training is no longer the benchmark.
- Is there a clear communication link? Does your CCTV control room have an instant, reliable way to direct your manned guards during a "Run, Hide, Tell" scenario?
