Phoenix, Arizona (CNN) -- Law enforcement and border security officials from all over the world swarmed an Arizona expo highlighting the latest technology in the battle against smugglers and drug cartels.
The fifth annual Border Security Conference and Expo was held here Tuesday and Wednesday.
"The key to border protection this year is mobility," organizer Michael Rosenberg said. "Anything that law enforcement can use to fill in the gaps between fixed surveillance positions along the border is drawing interest."
Vendors displayed innovations that make it easier to patrol distances between checkpoints and surveillance positions.
Leading-edge technology vehicles included a Ford F-450 truck equipped with a radar, and a night and day vision camera that can be used in rough terrain. The U.S. Border Patrol already has 34 such vehicles.
OshKosh Defense offered a "Tactical Protector Vehicle" that it boasts can be equipped with a high-caliber machine gun on a turret. The gray rig also has a thick shell that can resist bullets fired by an AK-47 as close as 18 feet, Oshkosh said.
Rosenberg declined to disclose what agencies would buy what equipment, saying that many deals are in the works and cannot be jeopardized.
Organizers said more than 1,000 representatives attended the event, including U.S. Customs and Border Protection, U.S. Department of Defense, U.S. Department of Transportation, U.S. Border Patrol, FBI, DEA, CIA, FEMA and law enforcement agencies.
