Need Help with Low Bitrate on Hikvision Camera

Hi all,

I have a Hikvision DS-2CD2387G2-LSU-SL camera, but its bitrate is stuck between 141 kbps and 1.48 Mbps, even though I’ve set it to 16384 kbps in the settings.

Some details:

I use the Hik-Connect app on my phone (no NVR).

The camera is powered via a Hikvision DS-3E0505P-E PoE switch.

Other cameras on the same network (Reolink) work fine.

I’ve tried changing settings, but nothing helps.


Could the issue be related to the Hik-Connect app, the PoE switch, or something else? Has anyone experienced this?

Thanks in advance for any tips!1000015543.jpg1000015544.jpg1000015545.jpg1000015511.jpg

Get rid of VBR and H.265

Use CBR and H.264 (h.264H is available)

And log into the camera itself with a computer. Dont use mobile apps to make camera/image settings

Thank you for the suggestions! I already tried changing from VBR to CBR and used H.264 (H.264H), but the issue persists with the same low bitrate.

For the camera settings, I always log in through a browser, not the mobile app, to make adjustments. I only use the phone to access the camera for screenshots, which helps me better explain my settings and diagnose the issue.

I’ll keep looking into the other possibilities, but I really appreciate your help!

With some Dahua cameras it matters what browser you use. Some settings wont be visible, others will revert as soon as you leave the page. Maybe similar with that HiK model?

Typically I recommend Edge in IE mode or Pale Moon 32
 
Hi... here's a similar camera set to 16384 Kbps on my system...

I don't think accessing the camera using Hik-Connect will use the full bitstream (it's using a transcoded stream?) ... looks like you have everything configured correctly... If you look at the live view of the camera when logged into it locally you will see the full stream. If you had an NVR, it would be recording the full stream.

I think what is going on is you want 16mb and get after all the lossy encoding is 2mb. So at the sensor is 16mb. At the NVR or BI for example the rate is peanuts. Seems normal to me. Just calculate the bandwidth of a 10 minute trigger at 16mb. Or someone doing constant records WOW. It's H.26X doing it's thing.
