Yeah tried adding cameras with 37777 port and recording is working fine now. Still don't believe port can issue in recording! Thanks a lot for your support!

Yeah sure I will try this..do u think any other problem with this? Thanks.

OK I will try this also..u meant to say try adding camera with 37777 port right? I have tried changing HDD also but still facing issue!

Yes onvif I think that is not cause of problem!

9988 port

camera brand is dhua. and some camera is IPC-HFW2100 with s/w version: 2.100.0001.0.R, build: 2013-01-19 some camera is IPC-HFW2100S-V2 s/w version: 2.212.0000.2.R build: 2014-05-12. and what protocol or ports u wnat to know? Thanks.

and there is no flaps in live view!

yes i am using surveillance HD. 4 HD of 3 TB. S.M.A.R.T status for one HD was "slight" so i removed that HD but still facing same issue. and we are using gigabit POE switch to power up cameras and patch cord is directly connected from this switch to NVR. there was only motion detection recording schedule configured on on each camera. so i also thought like u dcam so i changed every cameras recording schedule to general but still facing the issue. In the remote device where we add cameras . status sometime change to red. when ping comes properly.here is screenshot.

There r 16 ip cameras connected to cisco gigabit poe switch and uplink is given to Dahua 16-channel NVR(model:3816, firrmware: 2.610.0000.0). all camera are added in NVR. All cameras r connected at d1 resolution to 16-channel NVR. the problem is there is recording breaks in NVR. and sometimes status of added camera flaps greeen to red and red to green. i am attaching screenshot of playback.
