KABUL – AFGHANISTAN - While the world was watching Afghanistan's parliamentary elections on that Saturday 18 sep. 2010, Afghan National Security Forces and International Security Assistance Force officials had been keeping an eye on the capital with the help of a new security measure; the Persistent Surveillance System, which had took flight in that week at Camp Julien in south Kabul, is able to rotate 360-degrees to survey and closely monitor activity throughout the city. When used with surveillance data from other security systems, also helps security officials better anticipate threats. Suspended by a helium-filled balloon tethered hundreds of feet in the air, the aerostat provides high-resolution imagery and video and can detect possible enemy activities using its high-definition, infrared and thermal imaging technology.
