Wireless Telemetry
Telemetry for controlling PTZ cameras etc. cannot be transmitted directly over the
VideoWave but requires the addition of a Radio Modem to transmit the data. The
RM96XX series of modems is designed for use in the license free bands and is
approved for all European countries.
The modem is compatible with most commercially available video telemetry units.
Installation
The RM96XX modem can be supplied separately or mounted alongside the
VideoWave unit in an IP67 enclosure. (SED versions) Because the modem relies on
a good radio path, the installation procedure and test methods should be basically the
same as for VideoWave. It is always best to carry out a survey to ensure good signal
strength.
The 96XX modem will normally operate over a much greater distance than the
VideoWave system, therefore if a suitable site is found for the VideoWave, there
should be no problem with the modem link. Care must be taken in selecting the
correct antenna and the antenna installation. Follow the same principals as for
VideoWave.
If using remote antennas for higher gain or increased height, it is recommended to
mount the video and telemetry antennas a minimum of 3 metres apart, where
possible.
See the RM 96XX User Manual, supplied with the unit, for details on modem operation
and set-up. Application notes are available giving details of the modem settings for
most of the common telemetry systems.
