Best CCTV Cameras for Reading Number Plates (At Night)

Reading number plates at night is one of the most demanding jobs a CCTV camera can do. Glare from headlights, fast-moving vehicles and complete darkness can all make plates unreadable if the system is not designed for the task. That’s why number plate CCTV capture relies at night on more than just high resolution. Capturing number plates in the dark requires the right combination of camera technology, infrared illumination and careful setup to ensure plates are clear, sharp and usable when it matters most.

If you’re looking to track license plates at night, you’ll need to consider infra-red capabilities. The best CCTV cameras for reading number plates at night are specialised License Plate Recognition (LPR/ANPR) cameras with infrared (IR) capabilities,

This guide shares some of the key features and capabilities you may need if you’re reliant on a CCTV system that can detect number plates overnight, depending on the application and nature of the site or facility you need to protect.

Why Is Number Plate Recognition an In-Demand CCTV Capability?

Number plate recognition is widely used in policing, enabling the detection of lost or stolen vehicles, tracking movements, researching vehicle routes, cross-checking alibis, and identifying possible victims or witnesses. [1]

Advancements in technology have made ANPR cameras more accessible and cost-efficient, with options to either install standalone cameras solely for the purpose of managing access controls or car parks, or with ANPR functions built into CCTV solutions.

ANPR cameras are 92% accurate in identifying whether number plates are stolen or fake, demonstrating the precision and reliability of these advanced systems. [2]

What Should I Look for in a CCTV Camera That Can Read Number Plates at Night?

When choosing a CCTV camera that can reliably read number plates at night, make sure it has the right combination of hardware and configuration to capture sharp, legible plate images in low-light or no-light conditions. Here’s what to look for:

1. Strong infrared (IR) performance – Look for cameras with powerful and well-designed IR illumination that can evenly light number plates without washing them out. Good IR range and adjustable IR help ensure clear night-time capture at the distances you need.
2. High resolution sensor – A higher-resolution sensor (e.g., 4 MP or above) gives you more detail in the image. This extra detail is critical when zooming in on plates to read characters clearly, especially at a distance.
3. Fast shutter and good low-light sensitivity – A camera with good low-light performance (low Lux rating) and the ability to use higher shutter speeds reduces motion blur from moving vehicles at night. Sensors with larger pixels and noise-reduction help too.
4. Appropriate lens and focal length – The lens determines how close and how clear the plate will appear. Choose a focal length that matches the distance between the camera and the vehicle path so number plates fill enough of the frame to be legible.
5. ANPR/ALPR support (if needed) – Some cameras and systems offer built-in Automatic Number Plate Recognition (ANPR) or work with analytics that can detect and read plates automatically. If you want automated alerts or logging, this matters.
6. Installation and alignment considerations – How and where the camera is installed—height, angle, field of view and how IR lights are aimed—can make or break number plate readability at night. Proper setup tailored to the location is as important as the camera itself.

A summary of the most important characteristics for many settings is as follows, while noting that some use cases, such as ANPR on a high-risk construction site, may require additional features.

Another aspect is to consider how number plate detection will fit within your overall security approach, because scanning a vehicle and determining whether it is authorised is just the first automated process.

Businesses may, for example, need CCTV with instant notifications to raise an alarm when an unknown vehicle approaches, require gates and bollards that can prevent unapproved vehicles from entering or leaving, or use NSI Gold Monitoring services to investigate alerts and activate the appropriate response.

What Is the Benefit of Installing CCTV That Can Read Number Plates?

Number plate detection offers significant advantages, especially for sites with a constant flow of personnel and delivery vehicles, because it means they can monitor and approve every arrival in a timely manner.

Reading number plates at night requires more than just high resolution. The best results come from specialised License Plate Recognition cameras with infrared capabilities, properly tuned to avoid glare and overexposure while maintaining plate clarity.

Some of the many efficiencies and security improvements available include:

• Effectively capture speeding vehicles and unauthorised vehicles – especially at night, where crime is more likely to occur
• Evidence collection in case of a road accident incident
• Reduced pressure on guards or staff to physically intercept each vehicle and check the identities of the occupants.
• Automated detection of suspicious activity for cameras with AI-enabled analytics, identifying, for example, vehicles that return repeatedly or cars that have been on site for an unusually long time.
• Access controls, where gates and bollards lift automatically for recognised vehicles without any manual intervention or time-consuming processes.
• Real-time activity monitoring, with supervisors able to trace delivery times or compare on-time consignments, and stagger deliveries to avoid bottlenecks or delays.

Thinking through the purpose of your number plate detection, how it will integrate with other security measures, and how your cameras will be used will help you select the optimal devices with the necessary night vision for 24/7 coverage.

Frequently Asked Questions

How Can CCTV cameras read number plates at night?

CCTV cameras read number plates by combining the right camera hardware, lighting and image processing to capture clear, high-contrast images of the plate, even when vehicles are moving or it is dark.

How Can CCTV Cameras Read Number Plates?

Cameras with ANPR technology can differentiate between people, vehicles and wildlife and will recognise when a vehicle is approaching to automate number plate scanning. That information is then compared to a database to check if the number plate is known and approved.

In access control systems, responses are pre-programmed, such as activating an alert when an unrecognised vehicle attempts to gain entry or logging arrival and departure times.

What Happens if a Vehicle Has an Overseas Registration Plate?

Cutting-edge ANPR cameras can scan any number plates, including those from overseas, and conduct the same cross-checking as with a UK-based registration.
