I have the 16-channel hybrid Ultimate model. So far I have 8 analog and 4 IP cameras recording to it. The IP cameras are from two different manufacturers and are Onvif compatible. (The DVR recognizes them immediately.)

My question is this: I have all four IP cameras set to encode using VBR, but no matter what I do, the DVR always shows the encoding as CBR. Alll the other encoding parameters match except that one. If I try to set a camera's encoding to VBR from the DVR, it doesn't change anything (the camera is already encoding in VBR, but the DVR stilll shows CBR).

Is this a bug in the DVR firmware? How does it affect performance and recording?

Thanks.

As I know it the VBR and CBR affects the remote viewing. Basically the system is supposed to scale up or down per the network.  VBR Should scale per settings to improve viewing while sending less data. We have tested it both ways and always set up CBR. Still test and see what works best for you. If you have a heavy network load VBR may be better for you for video smoothness but quality will drop. Actual recording at DVR will still be good though.

When using ONVIF, there is only a guarantee that the DVR will be able to receive the video stream. Each camera manufacturer is responsible for how deep they want to integrate their cameras with another manufacturer's NVRs. All integration is done on the camera end.
