Carlos,

Worked for us. Was even enough to power an external HDD.

Yes, it is possible to change the lens to any other with C/CS/M12 mount. Assembly of that lens includes an C/CS->M12 adapter and spacers to make it fixed focused to infinity. Nothing is glued.

If you meant Sunex SuperFisheye EFL=1.3mm, F/2.0, M12 mount, here's a sample - http://community.elphel.com/pictures/hammer_camera/elphelimg_2421643.jpeg (2 in 1). The resolution is not perfect.

Well, we tested a 12V camera with HDD not too long ago - it works but it doesn't have enough power for extra boards (was instable with an extra MUX board and 2 sensor boards). In general there might be problems if the voltage drops below 12V - cables are too long or extra boards (mentioned above). 

The setup you need should work fine with at least 15ft network cable.

We could try to look for a 'better' adapter and order it from somewhere, I think.

Our current power supply is 12V, 1.5A.

Best regards and a happy new year too =),
