4) The antenna should be mounted vertically ideally, and exposed to
free space.
5) The equipment should be supplied with a clean supply in the range
5.9 to 16V and capable of 0.4A maximum. Care should be taken to
avoid direct supply from the vehicle 12V which can be very noisy.
Power conversion will be required for 24V vehicles.
6) The video input can be connected across long video cable lengths
so remotely mounted cameras should pose no problem.
7) The SOLO4 Bodywire transmitter has an IP66 rating, however
equipment should not be exposed for any long periods to any form
of liquids.
Overt Body Worn Applications
Body worn applications will either be covert or overt and this will dictate
the style of antennas and mounting of cameras. For overt applications
domo can supply a harness as shown below (domo part number
ACCBCH)
With all body worn systems the antenna should be selected to transmit
power away from body and domo recommends the use of the domo
body worn antenna (part numbers ANTBCL and ANTBCS).
Experimentation has shown that unlike traditional analogue systems,
front and rear antennas are not normally required. The nature of
COFDM and its immunity to reflections will ensure that the signal
normally bounces back to the receive site even when the operators
body is between the transmit and receive antenna.
