The value of the order and the number of units covered weren't disclosed but Cobham said both airborne and ground based equipment is involved.
The deal for the equipment, which will be used provide police with enhanced surveillance capabilities for the 2013 Confederations Cup and 2014 World Cup, was developed with a local integration partner following the opening of Cobham's Sao Paulo office last year.
"This is an exciting development for Cobham's Brazilian business," said Cobham Tactical Communications and Surveillance Vice President David Ashton. "We are proud to be working with our partner in Brazil on this important contract to provide enhanced surveillance capabilities."
Cobham's HD surveillance solution is independent of public or commercially available networks such as expensive satellite communications. Its video transmissions are sharper and clearer than ordinary standard definition.
