Why is BI displaying a lower frame rate than the camera puts out?

I set up a IP camera in Blue Iris. For testing I set the cam to Constant Bit Rate, best quality and 30 fps.
BI is reporting a main stream frame rate of around 10 fps.

The Max Rate in BI is set to 30 fps for this camera.

Make sure you are not using any special encoding choices.
You should use H264 or H264H, as set in the camera for encoding.

post your exposure settings as well as your network setup

The exposure settings are in Image-Display Settings-Exposure settings, correct?
If so, there is only:
Iris Mode: Manual
Exposure Time: 1/12


Network setup:
From the PC I have BI on, to a Netgear 1GBit switch to a Netgear 1GBit Switch to the camera.
Would this information be sufficient?

What cam is it? Maybe it can’t do 30fps at the resolution or other settings that you have set?

Why 1/12 shutter? That is one frame every 83ms, so trying to do 30FPS it won't happen as the shutter is open longer than 1 second.

Plus a 1/12 shutter will be horrible for motion. That is basically a wide open shutter and motion will be a complete blur.

At a minimum at night it should be a 1/120 shutter speed.

It is a Hikvision DS-2CD2142FWD-I and is capable of doing 30fps.

I do not remember why I set it at this shutter speed, probably because the image was too dark at night.
The camera cannot do some automatic shutter speed.
