All the guards are electronic ones. They are equipped with domestic radars
covering the entire distance of the 1000 square metres
and the territorial buildings, on the ground and first floors. Even if just
a single guard appears in the picture, be assured
that in actual fact there are many more.... A protected secret, their actual
number may not be divulged under any circumstances
! A rumour prevails claiming that the guards themselves are not aware of
how many they are ??? Inveterate gossips say that electronic guards simply
cannot count beyond two ! In that case they are
incapable of enumerating themselves. Whatever happens, in this manner the
secret remains a well-kept one !
