The interior ministry’s secretary for security Jose Antonio Nieto has confirmed interest in introducing airborne surveillance along the borders of the Spanish enclaves.
It comes just days after hundreds of migrants stormed into the country from Morocco by scaling the border fences.
Nieto has since personally visted Aeorum, a leading drone developer in Spain, to discuss the idea.
The drones would be equipped with heat-detecting cameras which would give early warnings of groups gathering to mount an offence at the border.
Despite Spain erecting high fences topped with razor and barbed wire, they are still being climbed over by migrants desperate to reach European soil.
Some 850 have managed to enter the country so far this month.
