Hik iVMS Flir view freezing

[Puffer 0]

Hi Folks

 

Setup : Existing Flir thermal IP Cameras FC313 & 324 on a perimeter with latest firmware, BU1.3.4. Ubiquiti AC WiFi back to a centralised server room. Hikvision DS-7612NI-E2 NVR with latest v3.4.95. Flirs using Onvif protocol back to NVR. Viewing station in the control room a Hikvision iVMS 4200 4 screen setup, v2.6.2.7. Flir stream coming from the NVR.

 

Problem : one or two if the flirs freeze on the view platform only at random. If you log into the camera and NVR web interface the live video feed is there and the recording is continuous. Only the iVMS feed is frozen.

There are 40-50 other brand cameras, mostly Hikvision and these all operate correctly.

It seems to be Onvif transmission related.

 

Any had any similar experiences and/or any suggestions ?
