Hikvision Poc CCTV audio

[dg_pug106gti]

I have just Installed Hikvision 5mp POC cameras: DS-2CE56H0T-IT3ZE
And just wondering if these have audio checked spec and can't see anything about it.
Just wondering as when setting up the NVR there were setting to select if recording video and audio and also to enable audio or not.
When it's enabled I can just hear a little white noise as if there is a mic but doesn't seem to pic up sound.
The NVR is one of these: DS-7204HUHI-K1/P
They have been connected just using a coax cable.

Thanks.

No audio as it would need an ‘S’ in the prefix. I think.

Thanks, I will just disable the audio in the menu then if it's not doing anything.
It's weird it sounds like there is noise being picked up like the background static you get from a microphone but no sound if I speak, you would think if no audio there would be nothing at all.

That will be white noise from the audio inputs on the back of the DVR you're hearing when you enable the audio on the video channel.
