What is IR Light

IR light, also known as infrared light, is the light in the infrared range of the electromagnetic radiation spectrum. IR is a type of light that is invisible to the human eye but can be detected by camera sensors. IR light is commonly emitted by IR illuminators, which are devices specifically designed to provide illumination in low-light or nighttime conditions for security cameras.

The primary purpose of IR light in security camera systems is to enhance their performance in low-light environments, enabling them to capture clear images at night or in dark areas. By emitting 850nm infrared light, IR illuminators allow security cameras to capture details that would otherwise be invisible to the human eye. One of the key advantages of using IR light in security camera systems is its ability to minimize light pollution. Since IR light is invisible to humans, it can be used for surveillance in areas where maintaining darkness is crucial. Additionally, the use of IR light enables discreet surveillance, as perpetrators may not be aware that they are being observed due to the dark appearance of the scene. Furthermore, images captured using infrared light are typically in black and white, as only white-light (wavelengths ranging from 400nm to 700nm) can be seen as color by human eyes in daylight or with added white-light.

Frequently Asked Questions

What Are Examples of IR Light

Infrared waves, also known as infrared light, are a type of electromagnetic radiation. Although invisible to the human eye, infrared light can be detected by humans as heat. An example of the practical use of infrared light is in remote controls, which utilize infrared light waves to adjust television channels.

Where Is IR Light Used

Infrared radiation is utilized in various applications such as heat sensors, thermal imaging, and night vision equipment. Additionally, infrared light is employed in both wired and wireless operations in networking.

What Does IR Light Look Like

In the realm of infrared light, objects that emit heat appear as vibrant shades of yellow and orange. Conversely, colder entities, like an ice cube, exhibit hues of purple or blue. To enhance our visual perception, we employ infrared cameras.
