Model Forum / Radio Controlled / Helicopters / September 2005

Hi,

I recently bought a 2.4 ghz RC camera to attach to an RC heli.

The system is a small camera with built in transmitter which connects
to a 9V square type battery (PP3).

This then transmits to a receiver unit which is connected via a
composite video cable to a belkin USB video input device, which then
goes into a laptop for recording and viewing in the field.

I have tested this set-up around the house, and the quality is pretty
good - however, how do you guys hook up your receivers outdoors?

I suspect most come with a 12V power adaptor like mine does.

I have everything set up for a "true" wireless camera system, but the
problem is powering the receiver.

This camera system is a cheap one I bought from Ebay (although the
quality is excellent). Sadly, it doesn't mention what the power rating
of the receiver is, but it looks suspiciously like this one:

Except my receiver has "KTK" written on it in the same font as opposed
to "JMK".

Has anyone with a similar set-up been able to power their receiver with
a 9V battery? My receiver does say 9-12V next to the power input socket
although no mention of current is given (may be 500ma if it is the same
as the one above, except mine also transmits audio).

Thanks!
