Rovio
Rovio is a robot webcam from WowWee http://www.wowwee.com/ .
Here's what I've done to get my Rovio working in Zoneminder with PTZ functionality.
Rovio setup: Create a username and password in the Rovio under Settings-> Security tab. Guest access should be fine. (As of this writting, the newer Java applet has not been tested) . Configure Rovio's Resolution to 640x480 and High.
In Zoneminder “Add new Monitor” -Set “Source Type” to “Remote” on the General tab The Source tab has more settings. It is the left picture. The right is the Control Tab. Later we will explain how to setup the Control Type and named “Rovio” (If you don't have a “Control” Tab, then from the Zoneminder console check the box in “Options” -> “System” Tab -> “OPT_CONTROL ”)
