How to improve town centre security by fixing the most common CCTV coverage gaps
Blind spots in a town centre security network tend to cluster in the same locations and follow the same patterns.
You might think the culprit is a lack of cameras. In reality, it’s cameras in the wrong places and footage that doesn’t support the decisions operators need to make. Many councils are also working with budgets that don’t stretch to full network replacement in a single cycle.
But closing coverage gaps doesn’t have to mean starting from scratch.
This guide covers the most common town centre CCTV gaps, what acceptable coverage looks like in practice and the questions worth putting to your installer or manufacturer before you sign off on the upgrade.
Where coverage gaps tend to appear in town centre CCTV
These areas account for most coverage failures in town centre security assessments. Not every location has all of them, but you’ll likely have at least three:
- Gateways into hotspots. By the time an incident is visible inside a hotspot, the approach footage is already gone. Camera coverage on the feeder streets captures subjects before an incident develops and records the direction they leave from, which is often the detail that makes follow-up possible.
- Late-night economy routes. Camera networks designed around retail and daytime activity often have gaps in the routes people take after closing time, when footfall disperses toward taxi ranks, night buses and fast-food outlets. Ask your installer to overlay late-night incident data against your current camera positions to see exactly where those gaps sit.
- Transport interchanges. A wide-angle camera covering a bus stop or taxi rank will confirm that something happened, but it won’t give you the facial detail or clothing description you need to act on it. Specify identification-quality coverage at specific waiting and boarding points, not just detection across the general area.
- Car parks and access roads. Inside a multi-storey, columns and layout make it very difficult to achieve reliable coverage across an entire level, and internal cameras often fail to capture usable vehicle detail anyway. The access road is a key area where a vehicle and its occupants can be captured to an identification standard, so it must be covered properly.
- Known congregation points. Incident patterns shift over time as venues open and close, pedestrian routes change, and new spaces attract footfall. Cross-reference your current camera positions against where incidents are actually being reported now, not where they were being reported when the network was first designed.
What acceptable town centre CCTV coverage looks like
More cameras don’t automatically mean better town centre security. A network of 200 cameras, all covering the same street, has significant gaps. A network of 80 cameras positioned around real behaviour patterns and incident data has far fewer.
Good town centre CCTV planning starts with one question: what do you need an operator to see, at which specific point, to make a useful decision?
That question has three answers:
- Overview and outline. Is something happening? A wide-angle view covering the approaches and exits to a public square lets an operator spot a developing situation and direct attention before it escalates.
- Discern and perceive. What is actually happening? This is where a pan-tilt-zoom (PTZ) camera works well. The operator holds a wide overview on a fixed camera while using the PTZ camera to zoom in and assess the situation in detail. Without that zoom capability, every alert requires a physical response to confirm whether it is genuine, which can be slow, expensive and mean response is actioned too late.
- Characterise, validate and scrutinise. Who is involved? Evidential footage requires a camera configured to deliver recognition-quality images at key points, such as a door, a barrier or a vehicle exit. Wide-area views won’t deliver this, but a fixed camera covering a single exit point will.
A system that only covers detection (or detection and verification) without identification produces footage that supports situational awareness but not investigation or prosecution.
How a mix of static and PTZ cameras closes the gaps
Many town centre security networks rely too heavily on one camera type.
Fixed cameras hold defined views well, but they cannot respond to events as they move. PTZ cameras cover wide areas and follow incidents, but when an operator swings to track a developing situation, the scene it was monitoring goes unwatched.
The practical answer is to use both for different roles. Fixed cameras provide continuous, evidential coverage, whereas PTZ cameras handle wide-area monitoring and operator-led response.
Consider hybrid PTZ cameras and redeployable CCTV:
If you’re working with legacy CCTV infrastructure, hybrid cameras make this approach achievable without full network replacement. These cameras allow you to migrate sites gradually, running analogue where it’s still needed and internet protocol (IP) cameras where they’re available, instead of doing a costly ‘all at once’ changeover. This way, you can focus limited budgets on the highest-priority locations, without replacing the infrastructure across the whole network.
Where a location needs temporary or flexible coverage, redeployable CCTV units can be positioned quickly without permanent infrastructure.
Ensure cameras are ONVIF compliant:
A multi-site, multi-era network will almost certainly involve cameras and recording platforms from more than one CCTV camera manufacturer. Without a common interoperability standard, those devices may not communicate reliably, which means operators cannot always pull footage from multiple camera types in a single interface.
So, if you’re specifying new cameras as part of a staged upgrade, make sure they are ONVIF compliant. Open Network Video Interface Forum (ONVIF) is the interoperability standard that allows cameras and recording platforms from different manufacturers to work together. Without it, there is no guarantee that a new camera will communicate reliably with your existing system.
What to ask your installer and CCTV camera manufacturer to show you
Before you sign off on any upgrade, ask your installer or CCTV camera manufacturer for these three demonstrations:
- Real-world footage from a similar location. Before committing to a system, ask to see footage from comparable sites and locations captured at night and in poor weather.
- A live alarm-to-operator workflow test. Start an alert at a known location and time how long it takes the operator to reach the correct live view, confirm the situation and log it.
- A coverage overlap review. Ask the installer to show you, on a map, which locations have more than one camera covering them and which rely on a single device. Single-camera zones become blind spots the moment that camera goes offline for maintenance or develops a fault. High-risk or critical locations should have overlap.
Redvision is a specialist UK CCTV camera manufacturer with over 25 years of experience in public sector and town centre surveillance.
Manufactured in the UK to the highest specifications, our redeployable CCTV Hub solution has transformed a once-disparate surveillance network into a streamlined, cyber-resilient system across 17 Sussex councils. Our PTZ cameras also continue to prevent and reduce crime, public disorder and anti-social behaviour for Bournemouth, Christchurch and Poole Council and many other UK councils.
All Redvision cameras are ONVIF compliant, so you can specify your council CCTV system with confidence that devices will work together and integrate cleanly with existing and future platforms.
