Knuckle47.. I had to (I guess) re-learn that old lesson.. "We get what we pay for". Now, having said that (& in X10's defense), I knew I was paying $159 for a two cam system, One color, one b&w. I knew the prices of other, better brands, but since my brother-in-law had a set, I went ahead & called X10, going for the cheaper. But.. after talking to the X10 rep, telling him what I wanted, & being specific.. then actually getting the box.. seeing what I actually got, I should have just sent it back for a refund, because I didn't get what I wanted. Freeze1.. it was exactly as you said, "Upgrade because they didn't have the part that worked with the system".
Now.. So after putting them all up, & getting them working.. I can't use them. So eBay.. here I come (someday). For now though they are boxed
