what plug system? mine has a usb, mini hdmi, and aux out behind the pannel. this is my only helmet cam, so i don't know what the rest look like. i did have to disect it to add an external mic though. should've mentioned that. i like tinkering though.
They're called PODZ or something like that. You would've had to buy a separate one that allows an external mic.
oh yeah, i don't have any of those. the more expensive models have more options on the camera. i opted for an old model and hacked it.
i dremeled right above the wrist strap hole a the back. i was lucky enough to only have to put a hole on the black inner part and routed it through the hole for he wrist strap. i never want to do that again. there is zero room in there.
