80km Long Range Drone HDMI/SDI Video and Serial Data Downlink

Model: FMS-8480
FMS-8480 airborne video downlink is a comprehensive aerial-based video transmission solution that delivers real-time surveillance that enhances law enforcement, emergency and critical infrastructure operations.

FMS-8480 is comprised of an integrated suite of downlink transmitters, receivers and antennas that capture real-time, reliable high-definition video from drones, helicopters and other aircraft for display at command centers, mobile units and on video management systems.

It is also integrated full duplex serial control data for flight and gimbal contro at same time by pilot on ground.
