Okay thanks I was planning on hooking up a couple at once now that I know the/a issueAnother thing, until you have the default IP address changed to a static IP address on the proper sub-net, only connect one cam at a time. If you connect two (or more) of the cams that have a default address of 192.168.1.108 none of them will be accessible as there is an IP address conflict. All cams and any other equipment on the LAN have to have unique IP addresses.
