How does a VECTOR speed camera work?

Each VECTOR camera records a date and time stamp alongside your number plate using ANPR technology. By comparing the time your vehicle was recorded at the entry and exit points of a speed-controlled zone, the system calculates your average speed across the full distance. If that average exceeds the posted limit, a Notice of Intended Prosecution is automatically generated. VECTOR cameras cannot be detected by radar or laser detectors — only a GPS speed camera detector will alert you to them.

What is the difference between VECTOR and SPECS cameras?

Both VECTOR and SPECS are average speed camera systems made by the same manufacturer and use the same ANPR technology to calculate average speed between two or more points. The key difference is physical size — VECTOR cameras are considerably smaller and more compact than SPECS cameras, making them easier and cheaper to install on existing street furniture such as traffic signals and lamp columns. VECTOR can also enforce a wider range of traffic offences beyond speed, including red light violations, bus lane contraventions and yellow box junction offences.

Can VECTOR speed cameras catch you if you slow down before them?

Yes. Because VECTOR measures your average speed over the entire distance between cameras — which may be hundreds of metres or several miles apart — slowing down at the camera itself makes very little difference if you have been travelling significantly above the limit between the two points. The average speed calculation accounts for the full journey between entry and exit, not just the speed at any single point.

Does a VECTOR camera flash?

VECTOR cameras do not produce a visible flash. They use infrared illumination to capture number plate images in all lighting conditions, day and night, without dazzling drivers.

What are the penalties for being caught by a VECTOR speed camera?

The minimum penalty for a speeding offence caught by a VECTOR camera is a £100 fixed penalty fine and 3 penalty points on your driving licence. More serious cases — where the recorded average speed is significantly above the limit — may result in a court summons, higher fines, or a driving ban.

Q: What is a VECTOR speed camera?

VECTOR is an average speed camera system launched in 2014 by the same company that makes SPECS cameras. It uses Automatic Number Plate Recognition (ANPR) to record your number plate at two or more points, then calculates your average speed between them. If your average speed exceeds the limit, a speeding ticket is automatically issued. Only yellow VECTOR cameras are used for speed enforcement — non-yellow units are standard ANPR cameras.

Launched in 2014, VECTOR average speed cameras come from the same manufacturer as SPECS average speed cameras. Like SPECS, they work by measuring the average speed of your vehicle between two or more fixed points using Automatic Number Plate Recognition (ANPR). If that average exceeds the posted speed limit, a speeding ticket is automatically generated - there is no discretion and no film to run out.

Beyond speed enforcement, VECTOR cameras are a multi-purpose traffic enforcement tool. A single installation can also handle:

Bus lane enforcement
Level crossing monitoring
Red light enforcement
Yellow box junction violations
Tolling and congestion charging
Access control
Parking management

Did you know? Not all VECTOR cameras are used for speed enforcement. Only yellow VECTOR cameras are speed cameras. Units that are not painted yellow are standard ANPR cameras used for other traffic management purposes.

The rise in popularity of VECTOR and SPECS average speed cameras has been driven by a dramatic fall in installation costs. The cost of installing an average speed check zone fell from around £1.5 million per mile in the early 2000s to approximately £100,000 per mile by 2016, making them a practical option for a much wider range of roads and local authorities.

What is a VECTOR speed camera?

A VECTOR speed camera is a compact, fully digital average speed enforcement camera. Unlike a Gatso or Truvelo - which measure the speed of a vehicle at a single point - VECTOR calculates how fast your vehicle has travelled on average across an entire section of road between two or more camera positions. This makes it impossible to avoid a fine simply by braking at the camera and accelerating away.

VECTOR cameras are typically mounted on poles at the roadside or on central reservations, and can also be fixed to traffic signals, street lighting columns, gantries and bridges. Their compact size compared to SPECS cameras makes them easier and more cost-effective to install on existing street furniture without requiring dedicated new structures.

How do VECTOR speed cameras work?

VECTOR speed camera at roadside VECTOR speed camera systems are commonly used to enforce speed limits on dual carriageways and roads with bidirectional travel. Cameras are positioned at the entry and exit points of a managed speed control zone, and at regular intervals along it.

When your vehicle passes the first camera, ANPR technology reads and records your number plate along with the precise date and time. When your vehicle passes the next camera in the zone, the same information is captured again. The system then calculates the time elapsed and the distance travelled to determine your average speed between the two points. If that average exceeds the speed limit, your number plate details and photographic evidence are used to issue a speeding notice automatically.

Crucially, VECTOR cameras cannot be detected by radar or laser speed camera detectors. Because they use ANPR rather than radar or laser to trigger enforcement, only a GPS speed camera detector - which uses a pre-loaded database of camera locations - will alert you to an upcoming VECTOR zone.

VECTOR vs SPECS: what is the difference?

VECTOR and SPECS cameras are made by the same manufacturer and use identical underlying technology - ANPR-based average speed calculation between fixed points. The main differences are:

Size: VECTOR cameras are significantly smaller and more compact than SPECS units, making them easier to mount on existing roadside infrastructure.
Installation cost: VECTOR's smaller footprint means lower installation costs, particularly where new poles or structures are not required.
Multi-function capability: VECTOR can enforce a broader range of traffic offences - including red light violations, bus lane contraventions, yellow box junction offences and congestion charging - in addition to average speed enforcement.
Lane coverage: Each VECTOR unit houses two cameras, allowing it to monitor two lanes simultaneously, either on a dual carriageway or in a bidirectional arrangement.

Can VECTOR catch you if you slow down at the camera?

Yes - this is one of the most important things to understand about any average speed camera system. Because VECTOR measures your average speed across the entire distance between entry and exit points, briefly slowing down as you pass a camera makes very little practical difference if you have been travelling significantly above the limit in between. The mathematics of average speed mean that even a significant reduction in speed near the camera will barely affect the overall average if the rest of the journey was at an excessive speed.

This is why average speed zones are generally considered more effective at achieving sustained compliance than point speed cameras - drivers cannot simply brake for the camera and accelerate away.

Does a VECTOR speed camera flash?

VECTOR cameras do not produce a visible flash. They use infrared illumination to capture clear number plate images in all weather and lighting conditions, day and night, without any visible light output to drivers. This means you will not see a flash even if the camera has recorded your vehicle. VECTOR cameras are also fully weatherproof and designed to operate in all conditions. Each unit includes a sun visor to prevent glare affecting image quality, along with a GPS clock, compass, accelerometer and dual light sensors to ensure accurate and consistent performance around the clock.

No film: always active

Unlike older fixed speed cameras such as the original wet-film Gatso, VECTOR cameras do not use film. There is no limit to the number of speeding vehicles they can record, and no need for periodic visits by technicians to collect and develop film. Your number plate, date and time stamp are stored digitally by each camera in the zone. If your calculated average speed between cameras exceeds the limit, a speeding notice is issued automatically without any manual intervention.

Images captured by VECTOR cameras can be transmitted in real time via communications media, or stored locally in a high-capacity onboard memory for later retrieval. The system records vehicle registration number, read confidence, time, date and camera location for every vehicle that passes.

VECTOR speed camera installations

30mph average speed camera zone controlled by VECTOR speed cameras The VECTOR speed camera can be installed on traffic signals, street lighting columns, gantries and bridges, giving highway authorities considerable flexibility in where and how they deploy average speed zones. Each unit contains two cameras, allowing it to monitor two lanes of traffic - either on a dual carriageway (same direction of travel) or in a bidirectional arrangement on a single carriageway road.

A growing number of local authorities are adopting VECTOR and other average speed camera systems in preference to traditional fixed-point cameras. In Lincolnshire, for example, fixed Gatso cameras on the A15 just south of Lincoln have been replaced with a three-camera VECTOR average speed check zone. This reflects a wider national trend as the cost of average speed camera technology continues to fall and the evidence of their effectiveness in reducing speeds accumulates.

Penalties for VECTOR speed camera offences

Being caught speeding by a VECTOR average speed camera carries exactly the same penalties as any other speed camera offence in the UK:

£100 fixed penalty fine
3 penalty points added to your driving licence
An offer to attend a speed awareness course in some cases, as an alternative to points

More serious offences - where the calculated average speed is significantly above the posted limit - may result in a court summons rather than a fixed penalty notice, potentially leading to higher fines or a driving ban. The Notice of Intended Prosecution (NIP) will carry the relevant code: SP10, SP20, SP30, SP40 or SP50. For full information on speeding penalties read more about speeding fines.
