I have built with both the original XCam and the XCam2. The 2.4GHz
transmitter is pretty solid and doesn't have any directional issues and only
suffers from the occasional flicker due to electrical interference
(microwave, etc.). I use one of the six AA battery boxes from Lego to power
the XCam and the XCam2. Seems to work fine. The XCam2 is exceptionally well
suited to robotic mounting. It is fairly light and screws easily to a Lego
8x8 brick. The Lego battery box is as heavy as another RCX though... Both
the XCam and the XCam2 need high levels of light to be effective. I have
tried several different models of low end cams and the low light levels seem
to be a chronic problem across all brands. Most of these cams work great in
sunlight or a well lit room. The XCam and the XCam2 tend to lose focus at
about 2 feet... As for better alternatives, my $700 camcorder with a X10
video sender looks great at any light level but is way to heavy for most
Lego robotic applications (unless you really like worm gear drives).
Pictures of the Xcam stuff are at my site.

I've read all of the past threads on the X10 camera products for use with
LEGO bots. Some questions for folks who have the Xcam2 and used it
wireless:
1. Is there a directionality issue with the 2.4GHz transmitter, does the
picture flicker when the bot/transmitter is rotating position relative to
the receiver?
2. Can 1 or 2 LEGO battery boxes be used to power the camera/transmitter, I
assume this is a yes from the X10 battery box specs?
3. How much does the camera/transmitter weigh, and what is the relative
center of gravity, low, high, mid?
4. What is the relative light sensitivity, does it need to be in a well lit
room?
5. How well does the autofocus work on close objects < 1 foot?
6. Does anyone have any better alternatives for wireless, color video?
Thanks for the info,
-Rob Doucette.
