ZLID stands for Zoom Laser Infrared Diode. Infrared (IR) is light that is just outside the wavelength of what humans can see. This makes it a covert illumination option that isn’t visible to the human eye but can be read by a camera sensor and converted to a clear black-and-white image. IR LED arrays are commonly used in the surveillance industry to illuminate scenes that are too dark for cameras to obtain a clear picture, however most LED arrays are only effective for a limited range of 300 meters. To go beyond that range, Infiniti has developed a technology called ZLID™ (Zoom Laser IR Diode).
