Video Breakup

[essjay]

Having an issue with the video breaking up as shown in the below recording. The camera is a Dahua HFW8630E-Z, 15fps, 30 iFrame, about 10000 bit rate.

Receiver Buffer in BI set to 20MB (max)

Any ideas?

try lowering bitrate to 4096 and see if it goes away.

You also need to match the iframe interval to the fps....
make sure windows is set to high performance and the hard drive is set to never sleep.

Yeah the drives should never sleep as the other 6 cameras (not including this one) are set to continuously record. Just set it to high performance anyway and set the discs to never sleep just in case.

OK, setting the bitrate down to 4096 seems to have fixed the issue. I'm able to raise it up to 8192 without the image breaking up.

Funny. I have Dahua cams as well, and 8192 is my maximum before I have issues too. Crappy hardware I guess, mine are the cheap Chinese knockoffs.
