Fault with HikvisionDS-2CD2342WD-1 4MP EXIR

[scooby73466]

2 of my cameras are as described above and one has suddenly stopped working with a message on my stand alone monitor "No network video". I have checked the connection into the NVR and that seems O.K. I wondered if anyone could help me please ? If I detach the camera from it's mount firstly is there any chance of an electrical shock. I was once told that on this type of camera the electricity needed travels down the same cable as the image travels back to the the NVR. Apologies if this is wrong but I just want to be on the safe side. My other cameras, including an NVR ,are working as they should.

What I am really asking is how do I determine if it is a cabling issue or if it is the camera that is at fault. Any help and/or guidance would be very much appreciated

is there any chance of an electrical shock.

No chance of a shock... it's low voltage....

What I am really asking is how do I determine if it is a cabling issue or if it is the camera that is at fault.

Take the camera down and try connecting it to the same PoE port on the NVR with a short patch cable. If the camera works, the cable is bad, if not, it's the camera or the PoE port on the NVR that is the problem.

Before you take the camera down, you can see if any power is being drawn from the port on a menu screen in your NVR similar to this:

Thank you so much for that. That is really appreciated. I will log in to the NVR and have a look at that.

UPDATE. This is a photo. taken from my standalone monitor, I can't do a screen dump. I'm not sure if I am in the right place but it is certainly showing that there is something wrong with camera 1 - Farm Drive. I only have 3 cameras on the system.

 

[johnfitzy]

What do you see if you select the "PoE Settings" and "PoE Binding Configuration" items?

 

[scooby73466]

Thank you for your continued help. It is very much appreciated. Do these images tell you anythhing ?

Yes, the camera is not drawing power, so it seems like you have a hardware fault... either the camera, the cable, or the D1 port on the NVR.

You need to take the camera down and plug it into the same NVR D1 port with a short/patch/test cable... if it then starts working, the cable to the camera location is bad... if it's a difficult cable to rerun, you could try re-terminating it with new RJ-45 connectors... if that doesn't work, you will have to rerun a new cable.

If camera still doesn't work after plugging it into D1 with the short/patch/test cable, then try plugging it into the unused D4 channel on the NVR... if it draws power there, then the D1 port on the NVR is broke... if it does not draw power there, then the camera is broke.

Happy hunting! Let me know what you catch!

Thank you again for your help. I did try something else today. There is another identical camera on the system and I swapped the cables over where they enter the NVR. The good camera still worked but the faulty one didn't and so I now know that the NVR ports are O.K. Another question if I may - What is the makeup of the cable that goes to the camera. Are there 2 wires ? One for the electrical supply and one for the data back to the NVR ? I am asking this because I seem to think that someone once told me that there is just the one wire inside the cable that does both jobs but I am probably wrong on that I would have thought.
Sorry, two more ! Is there any way of testing the cable if I disconnected it from the camera and is there any danger of really messing tings up if the cable was still connected to the NVR if I did that ? Thanks again for your help.

Good... you have confirmed the NVR port is working... But now you do have to take the camera down and test it with another cable to determine if it is the cable or camera that is broken.

From google:

"Power over Ethernet (PoE) sends both electrical power and network data through a single Ethernet cable, eliminating the need for separate power cables and outlets for devices like IP phones and access points."

So, it's just one Ethernet cable that handles data and power to/from the camera (there are 8 wires in the Ethernet cable).

No danger of "really messing things up" since it's already not working

You could buy a cable tester to test the cable such as:

RJ45 Network Cable Tester for Lan

Or you could take the working camera and plug it into the cable you want to test... I think I would just try taking the non-working camera down to test it with a new short test patch Ethernet cable:

10Gbps Snagless Cat 6 Ethernet Cable - 6ft, Cat 6 Cable, Cat6 Cord, Ethernet Cord, Black

You probably already have one!

 

[scooby73466]

Really helpful yet again , thank you. And thank you for the links. I looked at the last one showing the short test patch cable and it isn't quite clear on one issue. Does the cable have the same connections at both ends ? The one showing it plugged into te camera is slightly different.

 

[johnfitzy]

Does the cable have the same connections at both ends ?

Yes, same on both end... I just assume that these days everyone would have an extra/unused/spare one of these laying around somewhere? Check your kitchen draws, or a box you have somewhere with extra electronic equipment, or under your bed... you must have one somewhere!

 

[scooby73466]

LOL. You're probably right about that. I'll have a good look tomorrow. In the meantime thank you once again for all your help. I was going to get someone to come and fix it for us (I'm getting past all this now - I'm in my 80th year !) but I have got a tower that will let me get up there and work and I may well get it out when I have got one of those short cables (when the Head Gardener is away from the place - she will go beserk if she sees me any more than about a foot above ground level. Thank you most sincerely once again for all your help.

 

[johnfitzy]

Be careful... I'm sure the Head Gardener knows best!!!

Strewth, are you two related or something ?

 

[scooby73466]

This is the camera that isn't working. Firstly I presume that once I have undone the 4 Philips screws I will be able to remove the camera from it's frame. Then after I either have found a suitable cable amongst my collection or have bought the one in your link that I can just plug it into the same slot on the NVR and it will become apparent whether it is the camera or the cable that is at fault ?

 

[johnfitzy]

Yes... those 4 screws are holding a junction box cover to the junction box... if you take them out then the camera will come off with the junction box cover... then just unclip the Ethernet connection and the camera should be free. Bring it inside and test in the same NVR port...

How high up is that?... careful on the ladder!

 

[scooby73466]

Apologies for bothering anyone but I have found a couple of cables which I think are suitable for connecting the camera to the NVR. They both fit into te NVR socket and I have shown images of both cables which show the cable details as well as the plug at the ends of both cables.

You Sir will never know how much I am appreciating your help. Thank you very much. I am going to get my tower out to access the camera, I feel safer on that. I will update as soon as I can but it keeps raining here.

Yes, that is perfect to test with!

 

[scooby73466]

Thank you, That's just what I wanted to be told. I hope to get the tower out tomorrow and as soon as I've got the camera back in the office I'll test it and report back. Various other things on the go at the moment so this is having to take 2nd place but it is important to me that we get it back up and running ASAP. Just one thought that I've had. If I have to buy a new camera I shall buy one as close to the one that I've got spec. wise but will there be a palava in getting it up and running on my system or will it be just as simple as plugging it in and it will work immediately ?
Thanks again for all your help and guidance.
