SWIR (Short-Wave Infrared) refers to a region of the infrared spectrum, typically defined as wavelengths from about 1000nm to 1700nm, though some definitions extend up to 2500nm.
The visible spectrum ranges roughly from 400–700nm. SWIR lies beyond Near-Infrared (NIR) and requires specialized imaging sensors to detect.
Lighting a space at night is critical not only for capturing high-quality surveillance footage but also for deterring crime. Whether you’re managing a large-scale commercial site or upgrading a home security setup, the right lighting can significantly enhance overall protection.
Choose the Right Light Type: Infrared, White, or Hybrid
Match the Light’s Power Input to Your System
Match your camera’s field of view (FOV) to the light’s range & angle.
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.

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.

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.
