NV4108E-A2 POE Cameras "Failed to find network host"
Re: NV4108E-A2 POE Cameras "Failed to find network host"
Pogo and Revo thank you for your comments. I have been chasing this issue now past the return period on the cameras for Amazon. I will call Amcrest customer support tomorrow morning.
Re: NV4108E-A2 POE Cameras "Failed to find network host"
There is more than a good chance you'll be disappointed with Amcrest support and quickly discover it's a waste of time that could be better spent continuing your own logical troubleshooting.
And since you've installed many connectors, why not install six more on the three trouble cable runs just to cover those bases -- regradless of what the tester says about your voltage and continuity on the existing terminations. If you are using feed-through RJ45s, make absolutely certain they are cleanly trimmed with no stubs protruding. (I pull the pairs back a hair before crimping anyway just to be sure the connector will easily seat and snap. If you're using conventional connectors, double check the crimp (and crimpers) for a nice clean result.
Scrape the pairs with a razor blade to absolutely ensure you don't see shiny aluminum under what could be a thin copper cladding -- even if the cable says pure copper, (and hopefully solid and not stranded). As Revo mentioned, what's printed on the jacket isn't always what's underneath. But if it does happen to actually show CCA on the jacket, that's very likely your problem or a significant contributing factor.
Orange Stripe, Orange, Green Stripe, Blue, Blue Stripe, Green, Brown Stripe, Brown. You want continuity on all eight conductors just because.
Another simple test if you happen to have a regular switch handy would be to insert it between one of the longer runs and its NVR input with power being applied to the camera via its 12VDC tail. This would simply bypass the POE aspect at both ends. If the cabling and terminations are otherwise good, and there's no internal damage from toasted components at either end, the camera should fire up and come online...
...unless we're actually pissing up a rope on the POE angle and actually have a network configuration issue instead.
The results from your recent POE testing indicate there's 48VDC on the cable with a fluctuating current draw in the range of a typical IP camera at idle. That would seem to indicate POE functionality..., at least from the source. This is good. But what about data?
"Failed To Find Network Host" is indicating something is at least attempting to do so, but with an unsuccessful result.
So about the network aspect...
How are we determing the IP assignments of both the NVR and its cameras? NVR on the LAN handling the cameras via its own internal DHCP subnet?
What model cameras?
Have you directly accessed the cameras via their WebUI either by non-NVR POE or 12VDC adapter to examine what's going on there with no NVR in the mix? If so, did you make any changes that could possibly affect the NVR's ability to recognize them? Possibly setting static LAN IP addresses? If not, and you do happen to have a POE injector or appropriate 12VDC adapter handy, by all means log in to a camera or three and take a peek.
And to circle back to the POE angle for another quick question, and depending on which cameras, have you tested for IR functionality using the existing cable runs? If the IR LEDS work, at least there's POE to that extent which is usually on the higher end of the current draw specification..., and not likely your problem which would also support the results of your recent tester results and probably indicate a functioning camera.
If I were the Amcrest tech on your call tomorrow, I'd ask all the above questions and make all the same suggestions.
The only thing I omitted was "Have you tried a factory reset?" I'll leave that one for them. Hell, it may actually work!
Good luck. Keep us posted.

Re: NV4108E-A2 POE Cameras "Failed to find network host"
One Last thing I didn't mention that might change something... Looking over your post you mention that you think it might be a Transformer issue within the NVR. might be however I don't see that as the issue.. However you could check this by trying your longest cable in the higher ports 5-8. It has been a while since I have had one of my Amcrest NVRs open to remember what is what these days lol.. But if my memory serves me right it might be they share 1-4 and 5-8.. Or maybe that is just the programming of the switch. Seeing on the HS model anyway connecting a pass though cable from switch to NVR switch port 1 would only access 1-4.. It might be that each has their own Ethernet Transformer and if that is the way it is working then for sure isn't an issue with the NVR seeing it would be hard sale to believe that 1-4 Transformers in the NVR are all bad..
However I again personally feel it is camera issue
Ethernet transformers in the NVR and the Camera play crucial roles in maintaining the integrity of POWER and Data transmition. Any deficiencies in the transformers at either end can cause issues, particularly over longer distances. Ensuring high-quality and appropriately rated transformers in both the NVR and Cameras is important for reliable POE performance over extended cable runs...
Please note-- With data side of the Transformer being damaged as I think it might be, The camera won't work in 12v ethernet mode either.. If the camera is in fact a Wifi camera the camera can work on Wifi as I have said I now have 3 total 841w that are no longer sporting the Ethernet Transformers and will work in Wifi only..
NOTE 2 for people that might read this.. If your POE Camera won't power on using POE *And damage is caused by Transformer* then the camera can work using 12v Ethernet connection in this case.. Seeing OP states the camera is getting power but no data then there is in my GUESS of working on these cameras for some time that the damage is to the Data side of the Ethernet Transformer..
Wish you luck with your Support. Personally I would make a Ticket for your issue and could do this even now with them being closed. This could then after some back and forth be sent up to higher support with a call back from USA support staff. Different type of support from such contact.. However not sure there is anyone in Phone support that has a good working knowledge of the cameras Circuitry...

Re: NV4108E-A2 POE Cameras "Failed to find network host"
So I took the top of my 4116E-HS NVR that is an 8 port POE NVR with 16ch.. This NVR has only 2 Transformers and so as I thought the 1-4 and 5-8 would be on each of the transformers. Again while this is the case I find it hard to think that damage to all channels within the 1 transformer would be dead at distance.. I could see it as issue within maybe one or 2 of the channels. TBH the NVRs transformers are of a higher quality then the ones within the cameras. I still think it is a camera issue..
Edit: There is 3 if you count the one for the Local Ethernet. When I was talking 2 I meant 2 for the POE portion of the NVR. Just wanted to make sure I was clear.. The one for the LAN port is standard type that is in most of the cameras..

Answering Pogo's Post on June 30, 2024
Amcrest support was disappointing. They only suggested manually resetting the cameras by taking off the reset panel, which I did, which did nothing.
I verified the 4 pairs were seated in the connectors properly. The cable is Southwire Riser Cable, CMR, solid copper. I did verify using a knife and there is no aluminum present under the copper. CMR is printed on the cable wire.
The pairing follows all the previous CAT5e wiring I did in the house for the computer network and what is present in all the pre-made CAT5e cables I have following T568B. White/Orange, Orange, White/Blue, Blue, White/Green, Green, White/Brown, Brown
The IP address is not static. I added each camera one at a time and I have the following IP Addresses assigned. The status for all three is an Orange circle.
D 1: 10.1.1.128 Port 1
D 2: 10.1.1.129 Port 2
D 3: 10.1.1.130 Port 3
The LAN connection to the Linksys Router:
NIC Name: NIC1
IP Address: 192.168.1.104
Network: Single NIC
NIC Member: 1
IP Version: IPv4 (The DHCP switch is toggled ON)
Preferred DNS: 192.168.1.1 (unshaded)
Alternate DNS: 0.0.0.0
Default Card: NIC1
Virtual Host (switch is toggled ON)
I have not directly accessed the cameras via their WebUI either by non-NVR POE or 12VDC adapter to examine what's going on there with no NVR in the mix. I will do that next. I have not tested for IR functionality using the existing cable runs. If there is no network connection to the camera how is this to be tested?
As far as checking the data integrity, I will connect each of the three CAT5e camera cables directly to the Linksys switch, then connect a laptop one at a time to each end. I will make sure I have internet access and run a speed test, then a YouTube video.
Thanks again for all your suggestions. I am sure, as with all electronic hardware and software, there will be a simple solution to this issue.

Re: NV4108E-A2 POE Cameras "Failed to find network host"
Pogo,
My apologies. I have two Amcrest Model: IP5M-T1179EW-28MM camera and one Model: IPM5-D1188EW-A1-V3

Re: NV4108E-A2 POE Cameras "Failed to find network host"
Not sure if you posted the wrong wiring colors or if your cables are wired as you posted. However the T-568B isn't wired as you have stated..
The color should be as follows.. Also if yours is as you posted it can damage things..
White/Orange
Orange
White/Green
Blue
White/Blue
Green
White/Brown
Brown

Re: NV4108E-A2 POE Cameras "Failed to find network host"
Anyway reading back. Sorry I seen Pogo already gave out the Wiring colors .. Using what you have on a Network between computers or even the IP cameras in 12v format would be ok as long as each end is correctly wired to one another. POE on the other hand could work but because of issues that can come with it not being a standard wiring format could cause damage..
Be Safe.
Re: NV4108E-A2 POE Cameras "Failed to find network host"
The wiring should be agnostic if it is consistent throughout the LAN, but it is indeed the older 'A' convention and not the modern 'B' scheme. It may or may not be introducing mismatches, but correcting the terminations would be highly recommended for network consistency and integrity..., and possibly correcting the problem.
If the cameras will pull addresses from the NVR's dhcp server, they should pull addresses from whatever is assigning addresses to your LAN on the 192.168.1.1 network and be accessible on that network to investigate their default configuration status. Do that by simply plugging them into a switch on that network as you intend to do. Use 'B' convention jumpers/wiring just because.
Once you're in the cameras and can see what's going on there, it should be fairly straightforward to get everything else lined up and humming right along.
Aside from the color code, a solid approach so far that has eliminated a huge variable in the actual physical cabling quality itself.
You're getting close now.

Re: NV4108E-A2 POE Cameras "Failed to find network host"
The cameras are finally working. What a project! Thank you both for getting this over the finish line. I appreciate your input and guidance. I connected each camera to 12V and directly to the Linksys Switch. I reset each camera to its default settings, including the IP address, and cleared each camera out of the NVR. I redid the CAT5e connectors on each wire to the current T-568B standard. After that, I added each camera one at a time to the NVR. Each camera is now pulling a dynamic IP depending on the boot-up sequence after a power cycle of the NVR. I have done a shut-down and power-up several times and all is good. Thanks again!
