The Department Defense Orbs were used by The Department to guard detention facilities such as Dauntless Prison. When K9 tracked a Alien Jixen warrior to the prison, he was intercepted and disabled by the machines.(K9TV: Liberation)
The defense orbs were also used as stun mines, if someone got within its range, it would encase itself in a blue bubble, giving the person an electric shock. These stun mines were used as an attempt to corral a surviving Jixen warrior. (K9TV: Hound of the Korven)
Behind the scenes
In Liberation, they were CGI, whereas the stun mines from Hound of the Korven were actual models.
