Mic/speaker module for IP cameras (dahua/hikvision)

[sn34116]

I am using ip cameras from dahua (Ipc-hdbw4300e-as) and hikvision (DS-2CD2132F-IWS), want to try out the two-way audio feature they support. However they only have audio in/out interface (dahua uses RCA, hikvision has some 4-pin plug). I figure it probably needs a powered speaker and a external mic to work?

I searched on ebay / amazon, the closest things I found are mics, like these:

I was hoping for a mic/speaker module, the kind used for intercomm on doors, but I cannot find a fitting one anywhere.

A few ones are close to what I want: http://www.newegg.com/Product/Product.aspx?Item=9SIA1TY0YF3016 but I am not sure it would work with these ip cameras.

Anybody has experience on this?

Try this, based on recommendations from this site, this is working great with my hikvision and avoids the need for a power source. I just cut the plug off and hard wire it to the terminals on the camera
