I wanted to throw this one to the board and see if anyone has any good ideas for troubleshooting.
I have a Hikvision DS-7608NI-SE/P NVR with six DS-2CD4065F box cameras attached to it in "Plug and Play" mode. Most of the Ethernet cable runs are 75 to 100 meters however I have one camera at 130 meters with an Axis T8129 PoE Extender at 97 meters in order to split the run into two <100 meter segments.
Most of my cameras have been up for 4 days now with no problems however my camera on the 130 meter run using the repeater runs for 3 to 12 hours and then shuts down and shows "Offline (Network Abnormal)" on the camera management page of the NVR's web GUI. If I unplug the camera at the NVR and plug it back in to cycle the power it comes right back up and runs normally until it fails again later in the day.
I'm trying to figure out the best way to trouble shoot this error. My thoughts so far have been:
1) A poorly crimped or punched down connection somewhere along the path between the NVR and the camera. I'm not sure on this theory I figure the camera would either connect or it wouldn't.
2) The PoE repeater is too close to the 100 meter limit. Not too confident in this theory as Axis' documentation says you can do 100 meters for each segment.
3) The PoE repeater is not providing the camera with sufficient power. Not too confident in this theory either as Axis' documentation says you should still be able to provide up to 12 watts of power at 200 meters with a regular PoE source. The DS-2CD4065F camera maxes out at 9 watts.
Those are my thoughts so far. Does anyone have any other ideas on what could cause this error?
