anyone every look into any of the minature ELMO/panasonic/Sony Remote Head Camera w/ a control unit and feeding something like a Sony DSR-11 or Sony GV-D1000 or GV-D900
Viosport also makes helmet cams.
Looks like the ELMO's are higher resolution, 470 lines vs. 380 lines.
That was my idea, use one of these into a portable DVR.
Seems like there is a power box too, then the AV out to the DVR
It would be easy to disguise one of the helment cams as a pair of binocs.
Just get a cheap pair of binocs, and insert the helmet cam into one of the sides.
The wires could double as a strap.
