The present research article investigates the past and modern state in the zone of outdoor security. In the first part of the article, the sensory systems, which have been used for numerous years are described. Consideration is paid to the sensors using predictable ideologies of the recognition of the entities. New recent sensory systems together with their principles used for the defense of the outdoor environment are also described. Other problem is that older sensory systems of spatial protection were focused on the security of properties and buildings without expecting any change position in the time. The article analyzes also new possibilities of protecting of the outdoor perimeter even in the situations when the borders of the areas of interest are only temporary or mobile. As the Unmanned Aerial Vehicles (UAVs) systems have been used hugely and frequently involve modern multisensory systems, the last part of the article describes current sensors, which have been currently used to detect the UAVs systems and to guard the range of attention.
