The rig is entirely DIY made with wood, screws,13 switches, cables, 2 electric motors, 4 servos, an Arduino Uno connected to a PC via USB loaded with a Python script from principialabs.com, The camera controls can be manually overridden. The camera itself was bought on Ebay as “spare repair (the tape does not load)” connected to an Analog TV card, finally, the web streaming is handled by a piece of Software called Palantir. The whole hardware/software is Open Source. Any Camcorder can be used as the bracket is able to hold any moderately light camera hardware.
The Pan Tilt Kit is controllable via a web page via buttons (see flash animation above) and Ajax Dynamic Content. The web cam has two Zoom speeds and currently one speed Pan and Tilt, however it is capable of two speeds, still to write code to enable that.
Here are a few shots of the kit. Bear in mind this is a DIY job with cheap hardware!
Here are two short Videos showing the rig in action:
