or both (camera buffers cannot handle your network jitter).Īs a result, the camera drops multiple packets until the next frame, and encodes the keyframe (i.e.

inadequate camera buffers (either due to too small of a size or simply a poorly implemented buffer by the manufacturer),.

Sometimes the camera decides to drop a packet since it did not manage to send data in time before the 'send' buffer is over due to TCP is reliable and will not lose packets on the network layer but it can occur on the application layer, such as when a camera drops a packet.Įach RTP packet has a sequence number, and the camera puts packets into the 'send' buffer. Video and audio from cameras to the Server is almost always transferred via RTP over TCP. Network error detection in Nx Witness is very accurate and can detect even minor hiccups on your network that other VMS software would ignore. Note: The Nx Server log file will show a new entry indicating packet loss.

No data received for 10 seconds or more.

Connection to camera was unexpectedly closed.

Several possible descriptors of this notification are listed below: When Nx Server receives RTP packets and determines that packets were lost and/or did not arrive as smoothly (in the correct order) as expected.īy default, this triggers the “Network Issue'' notification in Nx Desktop on the Notification Panel that appears each time a network issue is detected.
