Secura HTR allows facilities using PESA SDI Video Distribution systems to restrict audio and video media sources by assigning any one of up to eight data transmission security domains (levels) to individual media destinations. Each security domain can transmit data to ensure that these media signals maintain their assigned level of security insuring an end-to-end secure source to destination authorization assignment. Using PESA’s intuitive Cattrax user-interface software, each Secura HTR device can be configured as either a transmitter or receiver for the ultimate in design and installation flexibility. With Secura HTR users can now easily segregate sensitive audio and video content within large SDI matrix engines.
