New day. New problems. I think it may go beyond ip cams. This am, the cam I set up last night was working on computer using direct ip and in NVR window. All other cams were out on the NVR page. They could not be addressed on computer by direct ip address. All of them pinged, however initially there was unreachable errors, but eventually pinged ok. I took out newest cam that was configured as indicated last night just using default ports and a static ip to see if it had caused problems but no change. rebooted computer, no change.I could not direct access any of the remaining cams by xxx.xxx.xxx.xxx:xxxx as usual. I will reboot gateway in a little while to see if any thing changes. Looking at my NVR recordings, most of the cams dropped off line around midnight 30. If you're thinking DCHP release, all have static ips so, don't know.
Some additional info, not sure if relevant, I have uverse gateway with four ports on back. I have a uverse DVR hooked to one port, an 8port swt hooked to one port. From the switch, I have the computer hooked, several devices locally, another switch to other devices, AND an ethernet that runs to upstairs 16 port switch. That's where hardwired cams are routed to thru a POE injector. I have hooked the new cam into the POE at two or three locations (locations where some of the other cams were hooked) and it works fine so assume POE is ok. From there another run goes to an entertainment center where I have another switch and a router used as an access point. 30+ devices hooked up and the only issues seem to be the cameras.
I'll post back after a couple of things: First I'll take down one of the older cams and reset to let gateway refind it using similiar setup as new cam. If no joy, I'll reboot gateway. Worse case, I'll reset gateway and start over.
