IR Illuminators provide IR light that enables true Day/Night day Security Cameras to capture clear images at night or in low-light. Infrared light is invisible to the human eye. True Day/Night security cameras are sensitive to IR light and can use it to capture images. Adding infrared light to a scene significantly improves the cameras performance in low light.

An IR Illuminator emits light in the infrared range of the electromagnetic radiation spectrum. With IR light, a scene that still looks dark to the human eye, is visible for security cameras with nighttime capabilities.

Radiation intensity: The radiation intensity of the 850nm Infrared LED is about two to three times higher than that of the 940nm IR light.

A video surveillance system has to be functional 24 hours a day in order to aid in the prevention of crime and the perpetrators prosecution. While designing a security system, it is important to consider lighting conditions as a factor that significantly affects camera image quality. Poor lighting conditions can compromise an entire system. Adding AXTON white or infrared (IR) security lighting will increase the effectiveness of your camera in adverse lighting conditions.

The human eye can see the light wavelengths in the range of about 380nm to 700nm. Light above 700nm in the infrared spectrum (IR Light) is not visible to the human eye. The shorter “near-infrared” wavelengths, which are closer to visible light, from about 700nm to 900nm, can appear as a faint red glow when looking directly at a high powered IR LED source. However, it is invisible to human eye as “light” that illuminates other objects.
