Hikvision IP Camera offline sporatically

All of my cameras are working, except one. It was working for about a day however it has now cut out and now no matter what I do it won't kick back on. It goes from not blinking at all to every 7 seconds to always on and blinking every 5 or so seconds (like in video).

Hikvision Hardware

  • NVR - DS-7608NI-I2/8P
  • IP Cam - DS-2CD2142FWD-IS
  • Cable - Cat6 24AWG UTP Ethernet Network Patch Cable
Video

I have uploaded a video of the back of the NVR and you can see how the light is solid and blinks randomly (Port 4 - far right top) while the others are constantly blinking

NVR backend Port lighting video

Tried already & checked

  • Appropriate Power is being received 2.9W
  • NVR will start to detect now but drops and says "IP Camera does not exist" or "Network unreachable"
  • I have switched out ports and other cameras work fine in port 4, so it is not the port
Possible issues

  • Cat6 cable is bad; however not sure why it would work fine and then just stop. The cat6 is from the same batch and all others work fine
  • Camera ip address issue - not sure how this would be since it was activated and working for about a day
 
One thing I noticed with my 7608 setup is the network cables for the cams are a bit lose/wobbly when seated in the sockets. I'm not sure if it's the cat6 plugs I'm using aren't 100% standard size, or the sockets. But it doesn't take much movement of the cable and the connection drops out.

Are they clicking and latching when you insert them?
If they are latched in you should be able to wiggle them around a bit with no effect on the connection as they are far enough in to ensure good contact.
 
568B standard

All the cables are Patch Cables (Pre-made) by Monoprice; I bought all the cables at the same time, as well as the cameras. So I'm guessing they all meet ANSI/TIA-568 standards.

I do notice it is lose a little however all the rest are the same and work just fine

Yep, they clicking and latching with no problems - I can't pull them out without pressing the little tab down. But moving them around makes them drop the connection :(

My plan is to reconfigure the cabinet and eventually run patch leads to the NVR, and see how that goes.

once again, did you use them as is, or did you cut them and crimp them to the 568B standard...how did you wire the ends? You cannot simply match up the colors at the ends, it must be to a 568 standard.

As I mentioned they were pre made/ pre terminated with RJ-45 plugs on the ends (thus not modified otherwise I would of mentioned that) so used as is and work fine for the other 5 ports/cameras. They are ANSI/TIA-568-C.2, not much material on ANSI on the backward compatibility.

Is 586B standard ( revision 2001) necessary for Hikvision even though it's technically an obsolete standard according to ANSI by about 16 years. Also all of the other patch cables (un-altered) work perfectly , so I'm leaning towards a bad cable or something on the camera end.

It just really gets me how it worked fine before and now it won't do anything.

You would be surprised what info Folks fail to post...a premade cable from monoprice will work it's wired same as 568b....when it's referenced here it's only with respect to the order of the pairs in the plugs..
 
It is a real pain to re run the Cable through my attic, can i simply duct tape the new cable to the old and just slowly pull the cable or will that damage the internal wiring?

Any help or suggestions on how to replace the cable (about 75 ft) and I live in FL so about 10 mins in the attic feels like a death sentence at the moment down here.

before wasting time running new cable, take the camera down and test with a short cable

This is a little late but if your going to run longer cable runs it might be worth it to purchase an inexpensive cable tester.
Just because the cables are new or pre-made doesn't make them faultless.
 
Hi,
I'm new to this board and this is late...
Do as Fenderman says with the short cable. Make it work in the lab, then move it to the field. In terms of pulling cables, yes, it is not uncommon to use an existing wire to pull a new wire. I recommend you get a box of pull string and tape that to what you pull so you leave something in the conduit. You should also apply lube. Don't use regular string or some crazy oil. There is stuff made for pulling cables. A little money spent will save you tons in headaches.

I am looking at the same symptons, but know it is not the cable unless I have some weather creeping in...hard to imagine this time of the year in my neck of the woods.

cheers,
Matt

My runs through the attic are approx 90', From what I've read, you can tape another cable to the existing and use it as a pull fish. But be careful not to snag it and then tug on it. The copper could possibly stretch, there is a specific ft lb ratting not to exceed for CAT cabling.
