Is it possible to get a Pinhole camera and attach it to your helmet and then connect it to a Sony Camcorder DCR-HC22E in your back pack? This is for a hiking holiday and recording mountain bike routes. The manual says that the HC22E DV has input/output via the iLink jack, so are they any of these small cameras what work with this interface? Also if they are what about power, is that from the camcorder. Any feedback, that would be great.
