Again, adjust the packet parameters on the camera to keep this from happening. You may also experiment with lowering Interpacket Delay. 6000 is a high default. On a good PC and NIC, this can be lowered to reach the fastest camera rates. The Missing Packet indicator, along with the FPS reading at the bottom of the screen are the guides for this operation.
