Does anyone knows the polarity required by a Unibrain Fire-i Camera?
I lost my power supply at a venue but I can't get a replacement in time, so need to some DIY solution quickly.

Seems that + is in the middle, and anyway they say "A built-in diode avoid any risk of voltages conflict or reverse current flow."
