Bit Rate

Hi,

I'm trying to learn how to use the manual settings on my Dahua 5442T-ZE camera. In the camera interface I have the bit rate set to 8192. However, when I select the camera in Blue Iris it displays about 1024. I have one camera for testing and I set sub-streams off for now. I do have direct to disk recording set. I'm thinking there is something wrong as I would expect Blue Iris to have the same bit rate as the camera. Is there something I'm missing or is this how it should be? Please advise. Thank you.

Martin

The camera is Kbps, BI shows kBps. K, when capitalized, means 1,024, when lower case, means 1,000. The B, when capitalized means bytes, or 8 bits, and when lower case means bits. I generally ignore the K vs k as the difference is 2.4%. In your case, you have the camera set to a max bit rate of 8,192 Kbps which technically equates to 1,000 kBps. So everything is correct.
 
Pretty much everyone gets the units and their abbreviations wrong, so quite often it is hard to tell what is going on. Heck, even I was not aware of a distinction between lower case k and capital K. I thought it was just arbitrary what people chose to write. LOL.

Thank you, very well explained.

Sadly... it still is for many. Then when you attempt to 'splain the implications.. you most often get the bewildered, silent blink response

Well, Spiff. That one takes the cake. I'm still chuckling. There should be an acronym for "bewildered silent blink response" (BSBR), but it would probably never catch on unless you could somehow attach that clip to it. Too good!!

I can't be the only one who saw this .gif glitching away and thought 'hey, that's an iFrame interval twice the FPS...'. :rofl:
