Power and non-powered switch hook-up been working great for several months now to run my 12VDC & 24VDC IP cameras into port 1 on my DVR?NVR, allowing DVR port 2 for my LAN.
Config Tool download fixed that issue.
Only real remaining problem is my ELI-SIP-EMVD-21R camera drops recording during the search review. I wrote more about this in another up-date I just made to another post I had made in the past about this particular cameras operational problems.
Thanks for the help getting some of the bugs worked out!
And I must say, I really like that "IPPTZ-EL2MPL-12X-Mni-O" PTZ camera in the months I have had it now.
Night vision on it is great in addition to the daylight stuff.
