Animals which are only nocturnally active (whether in their natural habitat or in the laboratory) or which live in dens provide a specific problem for the behavioral observer; namely providing adequate lighting for filming at the site or in the lab without influencing the animal's behavior. 

This problem can be solved with the new Tracksys Infrared LED array. This compact unit, packaged in a waterproof casing, contains a heat-sunk array of 90 infrared LEDs that generate only negligible visible light. This way the observer will have a good view of the animal, but not the other way around! 

The unit is especially suited for field work: running from a 12 V car battery it can illuminate up to 25 m distance. The Infrared LED array can be used with practically any monochrome IR-sensitive CCD camera. Video recordings made under these conditions can be
coded and analyzed with The Observer. Under laboratory conditions the array enables video tracking of animals with EthoVision in dim red light or complete darkness, for instance when studying circadian rhythms.
