Wireless Cam Sensor not available
Maybe I did TOO good of a job on it, because I've been overwhelmed with email requests to purchase the wireless camera seen here.
The Wireless Camera you see here is homebrew. This means I made it myself. There is no KellyEngineeringGroup company (Kelly is my surname and this was meant as a joke). It is not an official LEGO product - it is not available for sale - you cannot buy it from HiTechnic or other vendor. I took a spare (extra) Light sensor and took it apart to obtain the shell needed for the camera. There was no wiring or soldering or any special skills needed other than the abilities to squeeze out superglue and drill a small hole for the antennae.
What I can provide you is a link to buy the camera and receiver here. Thank you ALL for your emails, and I'm sorry that I can't make one for you. But it's not hard. $30US (plus shipping fees) will get you your own camera... consider supergluing a small 3L beam to the bottom of the camera if you don't want to sacrifice a sensor.
I won't be able to respond to any more emails about the camera... sorry.
