Hi guys, I'm truly astonished. Dealt with so many computer problems that turn out to be software related, and start playing with a mocap system to try and fix it. Plug in a camera to the base hub, and a minute later see smoke whisping out of it... Things get powered by the CAT6 cable so I guess it must have just fed it WAY too much power or something...

Well, yeah, I guess I'm not really asking anything - just - melting cameras smell bad :(

Smells almost like thousands of pounds on fire.
 
Pretty sure, I mean they get their power from the ethernet wire, which would I guess mean Power over Ethernet... Whether it's to some standard or just sending juice down a wire I don't know...
 
Thats odd. For reference (from wiki), the power levels are:

The IEEE 802.3af-2003 PoE standard (ratified June, 2003) provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA) to each device. Only 12.95W is assured to be available at the powered device as some power is dissipated in the cable.
The IEEE 802.3at-2009 PoE standard, also known as PoE+ or PoE plus (ratified September 11, 2009), provides up to 25.5 W of power. Some vendors have announced products that claim to comply with the new 802.3at standard and offer up to 51 W of power over a single cable by utilizing all 4 pairs in the Cat.5 cable. Numerous non-standard schemes had been used prior to PoE standardization to provide power over Ethernet cabling. Some are still in active use.

I'm going to go for faulty camera.
 
Thanks for the research, but deffo not a dodgy camera. In fact 4 have been burned. Daren't plug another in, as each is a few thousand pounds....
 
4?! Man you need to learn about Darwin.

Get another PoE switch and try it with that.
 
They work daisy-chained: a->b->c->d....

The PoE switch is a specialist hub...

Oh wells, sending it back to manufacturer etc.
