Recreate earthcam style hardware

[curlyroger 0]

I'd love to build something like this http://www.earthcam.net/products/megapixelcamrobotic.php

 

Has anyone tried to recreate or build something similar (on a budget)?

 

I'd like to be able to incorporate some/most of these capabilities:

 

• Fixed IP megapixel camera

• PTZ motor head

• Enclosure with wiper

• Ethernet controllable

• Cellular even?

 

All the PTZ motor heads I can find use Pelco-D serial controls. Would I need an Ethernet to Pelco-D converter?

 

I've built enclosures with fixed IP cameras hooked up to Cradlepoint routers so I can deploy via cellular in the field, but I have no idea how to make the quantum leap into PTZ motor heads and wipers.
