Airborne video surveillance plays a pivotal role in law enforcement, public safety, homeland security, and defense operations. Vislink’s airborne video downlink systems meet the challenge for top quality live video in air to ground applications under the most difficult urban, suburban, or rural environments. The AeroLink Transmission System is the next generation component of the Vislink Airborne Video Down Link System (AVDS). It features an agile IP based workflow that includes centralized management and distribution via the Quantum Receiver. The AeroLink Transmission System is a full featured 4K or 2 x 1080p 60 HEVC digital encoding video downlink solution built to address the unique requirements of aircraft downlink operations. The gains from the HEVC technology enables superior quality video with reduced bandwidth enabling larger geographical coverage. AeroLink features IP input, wayside user data and KLV telemetry information.  The video in may be HDR/UHD HD SD SDI, ASI or composite or via Transport Stream (IP). Key security features such as AES encryption and FIPS 140-2 are included with the AeroLink and are compliant with all aircraft regulations.
