How to prevent repeating echo from my axis cameras,

[jisun126 0]

When remotely viewing my camera from another location and using the 2way audio feature I cant get rid of repeating of my voice.

Is there a setting I have to enable to cancel the echo? I am using the built in mic on my axis 210a and p1344.

Is my line out speakers too close to the camera?

Not familiar with those cameras specifically, but see if they have a setting for half-duplex audio.
