It's true. Also, if you are like (probably) most of the consumers of this stuff, you bought into a camera pack up front and didn't like the software/interfaces and bought a pack like this to add-on. This was a GREAT bargain for me as I was setting up a system and found that I didn't have enough stuff and had to make a few orders to get all of what I needed for the job, which left me with some leftovers.
Anyway, it seems that most of the camera kits that include multi-view come with the video receiver and the USB adapter. I ordered two sets of cameras and each one came with both of those parts.
Glad you got one. Hope you get on well with the software. Approach with expectations that it will take you a bit of time to get things working like you want them. Some of this stuff is a little finicky and software has some work yet to be done for stability and efficiency, but it DOES seem to work as advertised if you put a little brainwork in - which it sounds like you are already doing.
