+This building complex sends a complex pattern of EM pulses and particle streams to reveal the location of objects in a system. After a while, all usual objects in a system are registered in a catalog so unusual occurences can be identified more effectively.

+The building complex itself immediately gets registered in the catalog and is very visible with [[metertype METER_STEALTH]] decreased by [[value BLD_LIGHTHOUSE_SELF_STEALTH_MALUS]].'''
