15 meters is too long for HDMI cables. We have a policy that when it comes to HDMI 10 meter is max, othervise transmitter/reciver or other solution. If over 4 meters dubble shielded better cables should be used. (This is of cource dependant on enviroment how mutch disturbance the cables can handle)
If the signal is 4k the lengths reduce further.
Have you tryed with a short cable to the not working camera?
As @tomas_vll mentioned, the 15m of HDMI is likely to be your issue, unless it's some extremely high quality cable, or an actively boosted cable, it's way too long.
But, even if you get that to work, what is it that you're saying isn't working? The KitPlus doesn't see the camera at all? The image from the camera doesn't appear (have you configured the endpoint so it does)? Just saying it's not working isn't very descriptive of what is happening. Can you provide more details?
