Hi,  I have a 8 channel Dahua tribrid DVR with 4 cameras, 1 is CVI and the other 3 are IP.  These are used to capture vehicles coming into our neighborhood.  I notice at times that the image is good for the first frame or two, then gets pixelated.  We do not have a great internet speed on this connection and I was thinking of changing the encoder bit rate type of the IP cameras to VBR from CBR to help maintain the video quality, but my changes do not save. 

So two questions, first will changing the bit rate to VBR help my motion images?  Second what is preventing this change from being saved?

My camera encode settings h264, 1080p, 5fps, 2048 bit rate.

Thanks,

Gary

Could you post the images or video clips here? I use https://streamable.com/ to do so. then use the link they provide. When it comes to License Plate capture you want to make sure that the vehicle is stopped or is going at a slow rate of speed. 

 

Here is an article.
