It is the fifth unit of its kind along the border and also the largest one so far.
It uses cameras that operate 24 hours a day and offer 360 degree surveillance capability.
"The video here that's taken by the aerostat is sent to a control room where agents are manned 24 hours a day, and they can send the agents who are out here in the field to that area to respond rapidly," explains Border Patrol Operations Officer Joe Gutierrez Jr.
