Hello, I'm having a problem I hope someone can help me with. I just purchased a DS-7108N-SN/P to replace my 7604NI-SE/P and I have so far been unable to power the camera via the onboard POE switch, it works fine with an injector. I had the same problem with the 7604 and therefore assume that I am not setting it up correctly. The manual is a bit ambiguous and I have been unable to find a solution via web searches. The manual says to leave plug n play selected in camera management for the POE to work but I never get lights at the port or data to the NVR. The run is a little over 100' of Cat5e. Any help would be greatly appreciated!

Normally the port lights immediately, then goes off briefly after a second or so, then back on, and should start flickering after 10-20 secs or so.
Hi I had similar problems with my 7604 and when I enabled DHCP instead of Static IP address in NIC Settings of my Hikvision camera and it start working ;-) You have to enable plug and play in your NVR to get POE to work . Let me know if that work for you too?

I had a similar problem; it turns out the port on the poe switch was bad. I confirmed this by plugging in a camera that was working into the suspect port, the different camera did not work either.
0658, thanks, That's why I ordered the new NVR, when my 7604 did the same thing I assumed it was a bad port or a bad 48v power supply, now I suspect it is either my lack of IP cam expertise or the length of the run/ quality of cable. However, two cheap POE injectors have done the job just fine so I have to assume the Hikvision NVR can do it as well. My camera is mounted up on a pole pretty high so taking it down to do tests with a short patch cable is impractical although possible if it comes to that.
The newer Hikvision cameras require a nvr with latest firmware for poe to function.
Your new nvr is a Chinese model since it is 'n' and not 'ni' with multi language firmware? Check the version. Most sellers are shipping it with v3.0.x but some are now sending with v3.3.4 which has compatibility with the newer cameras.
I'd suggest updating your 'ni' nvr to the latest firmware and try again. http://www.hikvisioneurope.com/portal/index.php?dir=Product Firmware/Recorder/DS-7600NI-SE 7600NI-V(VP)/ What camera are you trying to power?

spixel, I am attempting to power a DS2CD2132-I which is running 5.20 firmware. I don't recall the firmware version of the NVR but I'll check it when I get home this evening. I remember reading something about password negotiation problems for POE cameras due to the new password risk factors etc. Thanks for the link, will the DS-7100NI-SN firmware work even though it doesn't mention the /P for POE in the release? Thanks for the reply!
Failed to update the NVR firmware remotely 3 times, just hung at 0% and after 20 minutes I refreshed and the NVR was up without having updated or rebooted. Reset cam to defaults and tried plugging back into NVR, still no lights data or joy, tried setting cam ip to 192.168.254.2, 3, and so on with plug n play selected on NVR... no joy can try pushing update to NVR with TFTP but I don't think it is related to the firmware. Might just order another camera to avoid removing mine from the pole outside and try it with a patch cable. running out of ideas.
Mati07, Thanks, I did try DHCP on the camera with no luck, passwords are default and the same. It seems to me I should be getting lights on the POE port if it is attempting to communicate at all. I ordered another 2132-I camera today to do some testing with a shorter cable, until then I am at a loss for what else to try. I may upgrade the firmware on the 7108N-SN/P if I can locate some that works with it.
Wanted to update, after receipt of new Hikvision 2132 cam today POE worked immediately with a 6' patch cable. The problem assuredly resides with the length of the Cat5e run which is more than 100' but less than 150'. After all of my fruitless searches I hope I'll be able to shed some light for future readers. The cable I used is good quality solid copper 24 gauge, not CCA (Copper Clad Aluminum). It works with an injector which leads me to believe it is a voltage drop issue with the length of the run. Over the the next couple weeks as time permits I'll be doing some distance tests and attempting to make it work without an injector if possible. I wanted to thank everyone for chiming in with their advice and help, hope I can contribute to the forum somehow as I'm sure I'll be back with more questions in the future! ;-) Cheers -Andy

Couple of thoughts.
1) was the cable crimped using the 568 standard?
2) double check the crimps at the plug. A bad crimp can cause these types of problems.'
3) what type of injector did you use that worked?
I wouldn't think Cat5e should have issues at ~100-150 feet from what I've read.
I just had the exact same issue (builder terminated cat5e cables, and some cat6 cables) where I was getting no signal at all to the NVR. Of 7 runs, only 1 was properly working when I tested them with a network tester (assume you've tested each end?). On a few of them I was getting maybe 1 of the 8 signals as okay, but on many I was getting no signal whatsoever at both ends.
Builder came back to test, and turns out he had to replace all of the connectors with new ones as they weren't holding the cables properly. Not sure if he had used Cat6 connectors on Cat5e cables (I think the gauge is ever so slightly thicker on cat6), but given the cat6 ones weren't working either it seemed strange.
Though in your case if it is working with injectors, that seems fairly odd. Is there a device that tests signal strength from one end to the other? Voltage meter of sorts for data cables?
