Dahua Internal Microphone, any good?

Thanks for the input! I will power up the cameras directly from AGM Battery via POE injector as this system runs on Solar power.

In previous post you said you have hum, but also powering from battery? Because when I tried to power the mic from battery I got no hum, it was only the 12V ali power switching causing it.
 
I booked 1 PFM141 and will ship to @nayr for testing. These days also some guys ask for the PTZ using for the voice pick up device.

@EMPIRETECANDY do you have PFM140 in NL Stock? I will take this one again with my next order. I am very happy with this mic.
 
You can ask @EMPIRETECANDY from Aliexpress or for Germany me. But I am expensiver because of warranty and Mwst. which is included.
 
If someone would like to have a sound example, please write a pn to me. I can share a private link to you. It's from a hdbw4431 test run.
I really like the mic. It's making a fantastic job.
 
You could try what i did, buy a cheap USB microphone for about 25 $ (kareokistyle) and connect It directly to B I pc. Works fine and a differentsound compared to the small electret mic buildin the cameras. Also possible to use USB extender cord or a USBoverIP (havent testet that yet).

Its also possible to select sound from another ipcam mic in blue iris ! Dont miss that simple selection.

By the way... really impressed by Blue Iris !


Brgds.
