Pan and tilt commands are RF only and house code only. This is clear from looking at the camera remote (one code wheel for house code.) The RF command sent is received by all Ninja bases that are powered on (typically one per group of four) and all will respond at once. The unit code wheel on the wall wart is the address used to turn the unit (and attached camera) on and off. Turning one wirless camera on will turn the other three in its group of four off (which only makes sense as two on at once is a problem not just for the Ninja bases!)
And yes, you can create hardware macros to pan and tilt the bases to each of the four presets. I was able to recreate that animated demo on the X10 site in my garage and it is cool. What sucks is that they charge so much for this plugin. I don't use their unsigned video capture driver, so I could have done without 99% of it. If it didn't create a hardware macro for this it would be completely worthless (I can send anything from Misterhouse if I want to rely on a PC to run macros.) I notice it isn't particularly smart about updating the GUI either. The "Go Live!" button seems to be clueless about camera groups. Go figure.
Speaking of camera groups. There is one other fairly good trick this thing does in that it allows a 16 camera scan (as opposed to four with a camera remote.) Unfortunately (there always is one with X10 software), they have to all be on the same house code (not to mention the same RF frequency.) Why on earth should they have to be on the same house code? Why don't they let you enter the RF dip switch setting when creating the camera? I recently added that to Misterhouse's wireless camera package. It seems like such a no-brainer (eg if a camera is turned on, turn off all other cameras on that frequency, regardless of house code.) Then you could scan 256 cameras. I should add a voice command for that...
