Default Monitoring a video camera via a radio link

I wonder if anyone knows of devices to do this - I've searched the web and
can't find anything suitable...

I often use my camera on a stabilizer device (poor person's Steadycam) . We
are about to start shooting a new project and would like the others
(director, continuity person) to be able to see what's being shot. You
can't have a trailing wire from the camera when it's on the stabilizer, so
the ideal thing would be some video transmitter device mounted on the camera
with feed from the camera output (firewire, composite or S-video) and a
receiver that would output either to a monitor or a notebook PC (to be used
as a monitor). I know you can get a device to convert a video signal from
analogue to digital (if the PC were to be used) - but I can't see any radio
devices other than CCTV cameras (baby monitors etc.). Everything would have
to be battery powered for shooting on location. We wouldn't be bothered if
there was no audio transmission (we'll be recording sound to a separate
recorder anyway).

We are amateurs, so we can't afford anything vastly expensive. If anyone
has any ideas we'd be most grateful.

Many thanks,
Pete.

I see a lot of transenders that send the image from a VCR to a TV without
the need for wires would one of these connected to the video out phono
socket or S-Video out not do

You don't say how far you want to go, but something like Maplin
(www.maplin.co.uk) order code QM48C might do the trick.
It is sometimes possible to buy the bare modules from these devices - I have
a pair where each end is about the size of a couple of boxes of matches.
Runs off 5-6V, so a set of four AA will power the transmitter for about 10
hours.
Takes composite PAL and stereo audio and outputs the same at the receiving
end - I think I got mine from CPC.
Up to four channels.

Many thanks to Deep and Trev - I obviously used the wrong search words!
'Video sender' got me to the right sort of thing.

The range only needs to be a few yards and the signal doesn't have to pass
through any objects like walls. But the transmitter has to be light since
the stabilizer is a counter-balance system and all the weight has to be
taken with one hand - and my camera is already heavyish (DVX100A +
anamorphic lens). Most ads on the web don't say what the supply voltage has
to be (just 'power supply included').

So I'd be most interested if Deep has any more info on the modules he uses.
I looked at CPC's site and couldn't see anything any different from the
other devices that are available elsewhere.

The smallest looking devices that I've found are ref. SEME-BUD2.4GHZSENDER
from www.interneeds.com/cordless.htm (cheap and no SCART involved!). I
guess it might be possible to take the works out of the transmitter and put
them in another box that would also house the battery.

Anyway, thanks again.

Pete

Pete - sorry, I've had mine a few years, but I had quick poke at CPC's
website and found these:

http://cpc.farnell.com/jsp/endecaSea...=HK00649&N=411

http://cpc.farnell.com/jsp/endecaSea...=HK00648&N=411

Can't comment on them, but they look similar to what I've got - I'll go dig
in the attic for the manuals, which may give an mfr and an alternate source
They'll almost certainly come with a datasheet - sorry don't have a paper
CPC catalogue anymore.

Feel free to email - the address works .

Reply to own post - bad form, I know - got the website from the datasheets
from CPC.

These are the most recent versions of what I've got (AWM 605/606)

http://www.lprs.co.uk/main/product.i...?productid=206

Sub 20 quid (plus VAT) the pair - bargain!

Unusually, the Rx takes more current!

is this any good to you?

I've been searching for something very similar myself. Unfortunately the
above item is american and I need a UK device...

Deep - than you SO much for going to so much trouble with your replies and
for all the info. It looks as though it can be done pretty cheaply, as you
say. I shall have a go at building something with the modules you suggest -
I'll let you know when (if?) I get it to work!

Don't worry - should be a doddle if you can operate a soldering iron.
I've got mine in a couple of tiny boxes about 2" by 3" from Maplin, with
phono sockets for the audio and video, and a DC adaptor socket.
Email me direct if you have any questions/problems.
I forgot to mention, an antenna of just about 2 or 3 inches of plain wire is
all that is needed - unless you're going for extreme range, you don't need
one of the LPRS ones.
