I can't seem to get a K4 to see IP cams that use a port other than 80. I am using four Panasonic cams with port numbers 8000 thru 8003. I have tried addresses in ID as "192.168.5.250:8000" and "[Link: 192.168.5.250]". Neither seem to work. If I change the cams back to port 80, it works fine. What am I missing?
