ColorX Technology for Reolink Cameras: Seeing in the Dark

Reolink ColorX Technology

When securing your property, every detail is essential. To meet the diverse needs of many different users, almost all security camera manufacturers focus on providing users with both essential and niche functions. Night vision is essential for good security, but color night vision is a better and more useful feature.

As more people demand constant monitoring to keep their homes and businesses safe, many different types of night vision security cameras have emerged. Reolink, as a responsible and proactive security camera manufacturer, plans to introduce its brand new ColorX technology to the market to offer consumers high-quality color night vision.

ColorX is Reolink's latest color night vision technology designed for the newly launched product line of the same name. The cameras in this series feature F1.0 super aperture and a highly sensitive 1/1.8” image sensor to illuminate areas of interest in the dark. ColorX cameras can capture complete, accurate color images even in low light and do not require you to turn on any lights.

During the night, ColorX technology allows infrared and visible light to reach the image sensor of the security cameras. This feature improves the effectiveness of a 24/7 security system as it allows for improved color night vision in low light conditions, even when there is no electric light. Here are some important hardware components that contribute to the ColorX night vision.

Large Lens Aperture

A camera’s lens aperture is the opening part of a lens through which light passes and controls the amount of light that passes through the lens. It is calculated by dividing focal length by the diameter of the lens aperture, and the size is indicated by F-numbers, including F1.0, F1.4, F2, and F2.8. Lower F-numbers represent the larger apertures and increased exposure while higher F-numbers represent smaller apertures and lower exposure.

Normally, a darker environment means the camera’s aperture needs to increase in size to adequately capture video. A larger aperture allows more light to pass through the lens to the image sensor. Brighter light will typically require a smaller aperture to achieve optimal exposure. The lens aperture of the Reolink ColorX camera during the night is F1.0, over four times the F2.0 lens aperture of common security cameras.

Sensitive Image Sensor

An image sensor is the eye of your IP security cameras. A security camera image sensor ultimately determines what your security camera lens can capture and then converts the data into an electronic signal. Millions of light-sensitive patches make up these sensors to ensure that the footage collected is detailed and clear. A large sensor can collect more information than a small one, which means the video is typically much better.

ISO, the setting that determines light sensitivity in cameras, can be increased to raise light exposure. The number indicates the sensitivity of image sensors. Reolink cameras with ColorX technology use 1/1.8”, an ISO that is 115% higher than the more typical 1/3” sensors found in other cameras.

Lower LUX Level

LUX stands for lumens per square meter. One LUX is the amount of light cast by one candle in a one-meter space. All IP camera manufacturers use LUX levels to determine a camera’s low-light performance and ability to see in various degrees of darkness.

Most security cameras operate at a LUX CCTV rating of 1.0 or less. Some ratings are as low as 0.003 LUX. A lower LUX level indicates that the camera can capture more at night than one that has a higher LUX level. ColorX Reolink cameras are 0.0005 LUX, indicating that these cameras are highly effective at night.

Automatic ISP

To deliver true full color footage at night, one of the most important and complicated parts of the working process of ColorX technology is capturing light before transforming it into high-quality images.

ISP, the abbreviation for Image Signal Processing, is chip-level image processing technology which converts an image captured by security cameras into digital form. This process typically includes noise reduction, exposure adjustments, automatically focusing and balancing contrast, HDR correction, and image sharpening. For cameras, smartphones and other electronic devices, ISP is an important technology that directly affects image quality.

For Reolink security cameras with ColorX technology, the image sensors they use are semiconductor sensors that allow light to be converted to electrical signals. These image sensors, processing devices of the ISP technology, include features such as timing logic, exposure control, analog-to-digital conversion, shuttering, white balance, gain adjustment, and initial image processing algorithms. In low light conditions, image signal processing allows cameras with the upgraded sensors of ColorX technology to preserve colors of objects.

How does ColorX Technology Work

ColorX technology is primarily driven by two powerful components, the lens and the advanced image sensor. Reolink ColorX cameras can collect more light with a lot more precision than other night-vision cameras. The amount of light let in depends on how the size of the aperture of a lens is changed, and aperture changes cause the sensor to receive four times as much light when compared to a typical camera.

Once light has entered the camera lens, ColorX cameras use a top-notch, cutting-edge image sensor. The sensors in these true full-color Reolink cameras are far more adept at precisely converting light into a digital signal than those in comparable IP cameras. To maximize the capabilities of the sensors, ColorX technology makes use of a clever ISP technology.

In a word, the large lens aperture, high sensitive image sensor along with the powerful ISP technology allow the ColorX camera to capture more stunning full-color nighttime images.

With their complex working processes, the ColorX cameras are designed specifically for applications where high-quality color footage is required regardless of lighting conditions.

True Full-Color Night Vision

The F1.0 aperture and the powerful image sensor make it possible for ColorX security cameras to capture colorful footage even at night. Even in super dim environments, these cameras can capture all details of the areas you want to monitor and display full-color details of the scene.


The first thing you need in a high-quality security camera, night-vision enabled or not, is high definition. Also, high resolution is an essential component of a high-quality security camera; both high definition and high resolution contribute to clear, detailed camera footage that can be easily deciphered in the event of an incident. Reolink’s ColorX series of security cameras have a resolution of 2K 4MP to facilitate excellent image capture.

Smart Motion Detection

Just like other Reolink security cameras, ColorX cameras have an AI-based algorithm that can intelligently detect people, vehicles and pets and send real-time push notifications or emails with event snapshots to your smartphone or other devices. So, you can always keep an eye on the key areas you want to monitor and be aware of what's happening there.

Dual Warning

The 3000K warm light adds an extra layer of protection to your home or business. As soon as the camera detects motion, the warm light will shine brightly and the siren will sound simultaneously to deter intruders before a crime actually happens, which offers a dual warning system and additional protection. Futhermore, the light and siren can also be manually activated.

NVR Compatibility

Reolink ColorX cameras can work with Reolink NVR. As PoE security cameras, only Ethernet cables are needed to provide network and power to devices. To extend their storage capacities, you can connect these cameras to an NVR to store your 24/7 continuous recording and colorful night footage.

ColorX Technology vs Spotlight Color Night Vision vs Black-and-White Night Vision

To meet the needs of users wanting to capture footage of their properties at night, Reolink has launched different security cameras with various capabilities, from infrared black-and-white night vision to normal color night vision and advanced true full-color night vision. To make the differences between these options clearer, here is a table to compare the three types of devices.

Applications of ColorX Technology Cameras

The special color night vision features make ColorX cameras useful in many different situations. Here are some typical scenarios where users have found our ColorX cameras useful.


Whether you own or rent your home, ColorX cameras are a great addition. Some places, like staircases and balconies inside residential buildings such as flats, multi-level homes, and apartments usually aren't very lit at night, which can be dangerous.

If accidents or severe incidents were to occur in these areas, traditional CCTV cameras may struggle to capture the details of the situation. Cameras equipped with ColorX technology, however, are the best option when it comes to surveillance in low light conditions because they illuminate the area. This not only allows the cameras to capture better video but also makes the space safer for residents.

Small business

With ColorX technology, small business owners can increase the security and reliability of their security cameras in areas prone to theft and other crimes. Small coffee shops, warehouses, dark hallways, garbage areas, and other locations will benefit from color night vision. The dual warning system  that these cameras provide may help to deter thieves or internal misconduct, making both customers and staff feel safer when working.

Office and building entrances

ColorX cameras can also be placed at the entrances of offices or buildings. When the sun goes down and everybody inside the building leaves work, the placement of full true color night vision cameras can monitor what’s going on at night and will record all the evidence if an illegal break-in happens.

Streets and parks

ColorX cameras can also be used for outdoor security. Strategically placed ColorX cameras can provide a discreet security solution while bringing light into darker areas where people may feel uncomfortable in the dark, such as sidewalks, play areas, streets, and parks. Its 3000K warm supplement light can bring soft light to these areas but won’t disturb people passing by.
