Thanks to the so-called "Spy Cam",
it is now possible to travel and explore model railway layouts down to
"OO" gauge, without too much difficulty.
I was fascinated by a demo at "Steam" Museum,
Swindon, two or three years ago. This was by the Oxford "O" gauge group,
using security cameras, transmitting by wireless to a converted computer
monitor. I found the effect of running through stations - or stopping -
was astounding.
Getting down to a smaller gauge became possible with
cameras roughly the size of the top of your thumb, available from suppliers
such as Maplin and
Keene Electronics. I suggest that anyone wishing to experiment makes
sure they purchase a legal frequency for their country - 2.4 GHz in the
UK.
As the camera travels around the layout, it transmits
an analogue video signal to a receiver...which is plugged into a camcorder.
The signal could be fed into any other device, such as a TV monitor. A
combi TV could record onto VHS tape. The frame grabs below show a Hornby
bridge crossing and a GWR express on the main line, rushing past the camera
train.
