DIGITAL VIDEO SYSTEM ?GT500
COFDM - Video Transmission System
(Coded Orthogonal Frequency Divisional Multiplexing)

The GT500 is an exceptionally stable transmission platform in high multi-path environments, offering high quality low latency video images in conditions where traditional analogue methods fail.

The GT500 is suitable for body worn, mobile and temporary operations, due to its low current consumption; allowing efficient battery operation.

COFDM is a form of modulation that is particularly well suited to the needs of surveillance teams. Video signals transmitted using the old analogue technique were prone or susceptible to echoes and ghost imaging because the signal would 'arrive' at the receiver at slightly different times. The signal would bounce around off the buildings and/or landscape, these multiple signals would then produce a ghost or echoed image.

Video signals transmitted via COFDM completely address the 'multi-path' issue; the timing is such that the received signal is reconstructed back to its original form from the various multiple paths thus removing any echo or ghosting.

Using a diversity receiver increases the stability and reception of the
video link. Diversity can be increased to utilise four antennas in 'cell site' installations. We supply the system with a choice of frequencies to suit all operational environments.
