# Use External IR Illuminators with Verkada Cameras

An infrared (IR) illuminator is a tool that emits light in the infrared spectrum. IR light has a wavelength longer than visible light and is, therefore, invisible to the human eye, but visible to a camera. IR illuminators are built into Verkada cameras and have a range between 49–98 ft (15–30m), based on the camera model. There are times when additional light might be necessary for your camera to capture all activity in the field of view.

IR illuminators output at specific wavelengths and Verkada cameras are compatible with external IR illuminators that operate in the 850nm range.

Below is an example of what an IR illuminator can do to enhance the night vision of your Verkada camera. Depending on how much ambient light is available, you may find it best to supplement a larger IR illuminator.
