How Far Can a CCTV Camera See at Night?



Keeping your property, staff, and family safe is very important. Using the latest technology, especially security cameras, can significantly improve your security, particularly at night. In this blog, we’ll explore how far a CCTV camera can see at night and how this technology can help you achieve round-the-clock protection.


The Importance of Night Vision Cameras

Security cameras with night vision are crucial for monitoring large areas during the night. These camera systems use advanced CCD technology and infrared light to provide clear visibility in darkness, ensuring continuous, real-time surveillance of your property.


How Far Can Security Cameras See at Night?

Night vision cameras can generally see between 20 to 50 m at night, thanks to different types of technologies. This involves lighting up an area with light that is visible and invisible to the naked eye, allowing you to monitor your property 24/7, giving you peace of mind and deterring potential criminals.

Why Use Night Vision Security Cameras?

Night vision cameras offer numerous benefits:

  • 24/7 Protection: Continuous monitoring that deters criminals.

  • High-Quality Footage: Clear images in low-light conditions.

  • Remote Viewing: Access your camera feeds from anywhere.

  • Effective in Low-Light: Infrared cameras switch to black and white at night for better clarity.

Different Types of Night Vision Cameras


  1. Infrared Security Cameras: Equipped with infrared LEDs, these cameras capture clear images in complete darkness using invisible light.


  1. Starlight Technology: Enhances color at night, providing ambient or soft lighting that improves visibility and image quality in low-light conditions. This technology ensures that you can still get color footage even at night, offering better detail and evidence if needed.


  1. Active Deterrence Cameras: Active Deterrence cameras are IP cameras with lights, a loudspeaker, and a microphone (two-way audio supported on Turret cameras). 

These cameras provide full-color capability at night and feature built-in AI capabilities, offering advanced security features:


  • IVS (Intelligent Video System): Detects and analyses objects and behaviors.

  • People Counting/Queueing: Tracks the number of people in an area.

  • Heat-map: Visualises areas with the most activity.

These cameras activate lights and alarms when motion is detected, deterring intruders and capturing clear, full-color footage even at night.



Factors Influencing Night Vision Camera Performance

Several factors determine how far your security camera can see in the dark:

  1. Focal Length: A longer focal length narrows the field of view but can see further, while a shorter focal length offers a wider view.

  2. Aperture: A larger aperture allows more light to enter the camera, improving visibility in low-light conditions.

  3. Sensor Size: Larger sensors can gather more light, producing clearer images in the dark.



Optimising Camera Placement

The location and lighting conditions significantly affect a camera's performance. Cameras placed in open fields will have a wider field of view compared to those mounted on the side of a building. Additionally, artificial lighting from streetlights or porch lights can extend the camera's range.



Choosing the Right Camera System for Your Needs

Selecting the right camera involves considering the type of camera, its location, and the specific lighting conditions of your area. 



Conclusion

Night vision cameras help keep your home or business safe by improving security with advanced technology. While average cameras can see up to 60 m in the dark, factors like camera type, lighting, and placement can influence this range. By understanding these elements, you can make an informed decision to enhance your property's security.
