The Ministry of Justice in Korea has announced that the government plans on using UAS to monitor prisoners at three different penitentiaries starting in July, as a part of a six-month test operation of unmanned aerial systems.

The UAS, which will be able to fly at night, and will be equipped with a camera that can send real time videos, will be used for several tasks, such as patrolling the inside and outside of prisons, monitoring the movements of inmates, and tracing fugitives.

“Use of drones will help raise the efficiency of watching prisoners and save costs in personnel,” says a justice ministry official, via the Korea Times.

The UAS will also reportedly be used to “scramble when an emergency happens at nighttime or a fire occurs and responders are unable to gain access in a timely manner.”

Korea is quickly adapting the use of drones more and more, as the land ministry in Korea recently purchased four UAS, and began using the technology for safety inspections of hard-to-reach facilities and locations, such as high pylons and cliffs. The ministry will use the UAS to inspect more than 40 locations.
