SOLO4 - Bodywire Transmitter

The most important thing we build is trust

COFDM – Video, Audio Telemetry and IP Products

April 2009 Data Sheet

The SOLO4 Bodywire Transmitter is a COFDM digital
video transmitter from Cobham Surveillance, designed
specifically for covert video installations and body-worn
applications.

With domo technology at its core, the small size and low
power consumption (typically 4W or less) of the SOLO4
Bodywire make it the product of choice for covert video
hides, or applications requiring long term battery power
deployments, small unmanned aerial vehicles, and body­worn or bodywire use.

The SOLO4 Bodywire transmitter employs MPEG2
encoding (MPEG4 is also available) for excellent image
quality retention. Equipped with integral COFDM
modulation, the SOLO4 transmitter is ideal for
establishing rugged wireless video links in all
environments, including mobile and urban environments.
Offering several user-selectable modes that trade off
image quality against range, the SOLO4 transmitter is
ideal for all mission types. The SOLO4 Bodywire includes
RF up-conversion and PA circuitry to make a complete
single board transmitter. SOLO4 Bodywire is supplied in
a simple lightweight case with attached Lemo cable
connectors.

Security is ensured with optional AES128/256 Encryption.

The SOLO4 Bodywire transmitter will transmit images in
a non-line of sight environment up to 750m, depending
on mode and frequency; further range can be achieved
with the booster PA.
