Looks like this cable plugs into a headset output...
Good idea, And my PS 7000 I think is a 4 place intercom...so I could in theory rig up a third output just for the camera...In fact I could save the $31 for this cable and make my own flying lead hardwired to the intercom with a jack that plugs directly to the camera.
Of make a splitter (maybe this is what the As$S cable does) so one of the existing headset feeds is also feeding the camera.
A lot of wiring to b flopping about though.
great idea though thanks..
