Infrared lighting is essential for hidden video surveillance without visible light. It uses LEDs in the infrared spectrum to illuminate objects for cameras while remaining invisible to the human eye. Infrared illuminators have many advantages including low power consumption, small sizes, high image definition, durability, and lifetimes over 10 years. They are used widely in security applications like preventing crime, terrorism, and smuggling in areas like warehouses, ships, ports, tunnels, railways, buildings, and outdoor perimeters.
