No it doesn't sucks. When did you tried it the last time?
Maybe I am the only one here who tried it with the newer ones.
I wrote that it couldn't replace a baby phone, but this has other reasons.
2 way audio means with the actual app version, that both ways are on. Together. That's nearly duplex, and it's working when mic and loudspeaker is set up with the right volume ok for talking with my 4 and 6 year old children´s from the office. If you activate speaking mode with tha app, it energized the speaker and frequency range. Not as perfect as tinycam which energized the mic much more. It works like village stations from several manufactures using videostations i know.
It has no echo cancling, and the audio latency is noticeable (around 1s) because it´s not a voip conncetion.
So in my opinion it´s defiantly no junk, i have used it with my old cam for years and when you know how to use it and under what conditions its doing its job very well.
With the dahua external mics and a simple active cheap desktop loudspeaker you have all you need for that. But i would recommend tinycammonitor, it works better for 2 way audio.
I don´t like the ptz ones for a children room. In practice you forget to point the cam to the desired position and zoom before someting happens. In cases you hear something and want to have a closer look, my children's are afraid of the red lights and sound of the cams. Especially on a nightmare dream. There are several sleep phases, where i can guaranty, waking up both of them for any cam movements. Maybe an result of my old suneyes and foscam, which are not silence. And they have many light from status leds...

this ptzcam with integrated mic and speakers. I tried the ipc-k wifi ones and they are horrible at night view, the speaker is bullshit, every babyphone has a much better one. for the same price a 4431 version is much better.
