NVR Preview Slow to View

Postby cosmarchy » Sun May 07, 2017 6:04 pm

I have a DS-7604NI-E1/4P/A with two cameras one DS-2CD4A25FWD-IZS and a DS-2CD2745F-IS.

When I log in to the DS-7604 and click on the Live View button, the DS-2CD4A25FWD-IZS is pretty much instantly displays however the DS-2CD2745F-IS quite often fails to display an image, and it is becoming more problematic. If I stop and restart live view a few times it eventually works. I also get the same issue on my phone using iVMS-4500 HD.

Does anyone else have an issue with a camera not displaying on an NVR? I'm sure it is the camera but not sure what I can do about it.

Thanks

Am I correct that the problematic one is a 4mp camera? If so, try a test and lower the resolution of the camera or try using the sub-stream channel to see if the picture resumes. If so, I just went through a similar issue that I am still trying to prove but that is in Safari for MAC. Start with that test first.
