Security cameras are effective monitoring tools for large, industrial facilities. The devices allow operators to view targets from safe distances, with minimal direct contact. In some cases, a set of security cameras connected to a single network can be deployed to streamline monitoring of tanks, main pipelines or valves. In order to extend the functionality of security devices for nighttime applications, it would be worth considering the use of powerful infrared LED illuminators.
Extending Range and Visibility
Nighttime security cameras rely on infrared LEDs as a primary light source to capture images in the dark. The non-visible beams can help monitoring devices ‘see’ objects hundreds of feet away. Additionally, saturated beam angles may also boost visibility in locations that experience a lot of haze or smoke. This is particularly useful when checking for gas leaks on external surfaces of tanks and large compartments.
Compared to using a standard, visible light source, infrared LEDs are more discreet and applicable to facilities in high-activity or urban locations. Because the beams are non-visible, operators do not need to worry about light spillage on roads, nearby buildings and sidewalks.
Infrared LED illuminators incorporate rugged designs, due to their extreme applications. The units provide 50,000+ hours of continuous illumination. This lifespan can be extended using photocells or timers that only turn the light on when it is needed. High-quality infrared LED units offer extended operation, beyond the lamp’s expected lifespan, at reduced intensities (retention). The can be used as stationary or portable work lights.
During illumination, the lamps do not use infrared filters to generate infrared beams – as commonly seen in incandescent infrared light sources. Instead, the units incorporate diodes that generate the specific non-visible band. This not only improves the quality of the light, but also decreases maintenance, since there is no longer a need to install a separate filter on the LED illuminator.
