Hi We have a DAHUA IP system, based on the following hardware: 1 - Dahua NVR 5832 26 x Dahua IP cameras with a maximum of 1MP We have successfully configured and installed the NVR, cameras and the PSS software. We want to be able to view all 26 cameras simultaneously from 4 different PC's, all running the PSS software. However, we are having issues as the video stream feed on all 4 PCs regularly is delayed and freezes. We have tried to reduce the bit rate and fps, but to no avail. I have used a network monitoring tool to study the packets being sent between a PC and the NVR, and noted that packets are being sent via the TCP protocol. Is this normal? I thought that live video streaming is done over UDP? I have also noted the multicast transmission feature on the NVR. How can this be configured? Any help is greatly appreciated.

For some reason, there now seems to be an issue with the recordings. We have noticed that we have missing recordings at 5 minute intervals. We have updated the NVR/cameras with the latest firmware, but it seems that there are issues with the motion detection. Any ideas as to the cause of this issue?

Hi guys Thanks a lot for your input everyone. Re zero channel feature, even with the latest update our NVR didn't have this feature. Eventually we tweaked the settings of each cameras and managed to find a solution; now we have a setup whereby the cameras are accessed through 4 separate PCs and 3 phones. Thanks once again

Even if the network is dedicated to the CCTV system with dedicated gigabit switches? Would a better NVR be able to handle multiple clients better, or is requirement simply a no go for an IP CCTV system?

When you refer to bandwidth do you mean that the limit is due to the NVR or to the network system? Would it be possible to set video stream to UDP or that won't help?
