+1^^ to @Mike A. words above.I read it on some website some where. It said switch to router connection required a crossover cable and everything else was straight through cable.
Ha! I thought they were still required also... just googled to see when that might have changed:Back before Auto MDI/MDI-X ports on switches and PC LAN ports became common, you did need a cross-over cable for certain situations
Well see, this is exactly why this forum rocks. Not so technical people like myself can get technical questions answered by honest members. I was a Special Systems tech (commercial, security, fire, access control, CCTV & life safety systems installation) for ATT Integrated Technologies, Honeywell and sub contracted at Intel for Orion Security Specialist but 20 years later a simple ethernet cable question stumped me. Hold on, to save myself from being persecuted by simple common industry standards, like I said it was 20 years ago when I was a SST, lol. Back when crossover cables were commonly used.+1^^ to @Mike A. words above.
Back before Auto MDI/MDI-X ports on switches and PC LAN ports became common, you did need a cross-over cable for certain situations, like PC to IP camera or PC to PC, now that's no longer a requirement with modern networking devices. That being said, you could use a cross-over cable PC to PC and if both are Auto MDI/MDI-X ports then it would work anyway (but it's not necessary).
You know... I googled before I wrote that to make sure ground was pin 7... was a bit surprised it was pin 5... did not realize I was looking at a pinout for the DB-9 connector... I had always worked with the DB-25 and you are right 1990 was probably when they went out of style... along with the last of the DEC VT-100'spin 7 was ground
Even TX & RX were swapped between the DB-9 and the DB-25 but it didn't matter because it was 2 to 3 and 3 to 2 on BOTH 9's and 25's for a null modem cable.You know...

I plugged the ethernet cable into port 8 of the POE switch, link below, and the other end of the cable into the router, still no video. What am I missing here?You connect one of the ports to another switch or router.
Both of my cheap cable testers told me the cable running to the router from the POE switch was open or the cable length was to long but the continuity test on both testers said the cable was good. The specs on the cheap testers say they accurately read up to 360' but the cable run isn't more that 200' so yeah you can say I have no hair left. But come to find out, the rj45 connectors I was using, links below, are basically junk so I found some other connectors that are easier the use and fit in the sockets better, last link.Now you have to go into the NVR and manually enter each camera - the NVR will only "auto populate" the cameras connected to the NVR POE ports.
Any cameras coming into the NVR via the WAN/LAN port need to be manually entered.
