Well Dave I guess I spoke a little to early. All was working well until I got up this morning. Now for some odd reason the XC21B isn't showing up on the computer. I have controll of it. In the since. I can rotate right, left, up, down, but the picture is not coming in on the computer. I have my B/W on C1, the XC21B on C2, and the other color ninja's on C3, and C4. There all working fine except the XC21B. I reset the camera just in case there was a problem there, but that didn't help. On the bench test it fuctions. How ever I can't get a picture to come up properly, and the cameras within 6 feet of the receiver. So thats not the problem. I even tried unplugging all of them and just running the one I was having the problem with. Still no luck. I plugged the others in one by one and they came on with no problem. So I don't know I'm getting tired of this. Just not sure what to do about it. I have so many other things I need to be doing besides messing with this everyday. HEELLLPPPPP!!!!!
