Cerberus, The Hound of Hades

CCTV Guards have taken the symbol of Cerberus, The Hound of Hades as their logo as it was the primary security guard of Greek legend.

KERBEROS (Cerberus) was the gigantic, three-headed hound of Haides which guarded the gates of the underworld and prevented the escape of the shades of the dead.

Kerberos was depicted as a three-headed dog with a serpent's tail, mane of snakes, and a lion's claws. According to some he had fifty heads although this count may have included the serpents of his mane.

Herakles (Heracles) was sent to fetch Kerberos as one of his twelve labours, a task which he accomplished with the aid of the goddess Persephone.

Kerberos' name perhaps means "Death-Daemon of the Dark" from the ancient Greek words kêr and erebos.
