Or how to install
on the craddle a video camera with a video transmitter,
and get on the ground a video receiver and a nice viewing.
A video link
needs:
an aboard
camera or a video output
an emitter/receiver

The camera:
First, an image must be get:
The emitting/receiving system
Then image must be transmitted
with an emittor and a receiver. the input of the emittor
is linked to the camera video output. there are two kinds
of video transmission: as UHF, or in GHz.
In UHF/VHF only the emitter
is specific.
The receiver is only a normal TV
set for hertz signals. The range is often limited to a few
hundreds meters. Equipment can be purchased for a hundred
Euros.
I don't have experience on the
equipment to-day on the market.
Having used this system for a while
some years ago, I finally abandonned it when the TV-walkman
I was using as receiver went out. The most inconvenience
was to be obliged to re-adjust the frequency each times
a near TV broadcasting emitter was covering the same frequency
than the one already set.
In GigaHz,The equipment
consists of an emitter and a receiver. The transmission
range is of several hundreds meters, even more for the most
powerful ones.
Prices are also higher, over 200
euros.
It is the transmission system the
most reliable.
Viewing:
The receiver is linked to a viewing
equipment which have a video input PAL or NTSC: TV set,
video-screen, camcorder, DVD reader. The most convenient
viewer that I know is a camcorder viewer, recovered on an
old one.
