This is like the 3rd thread you have started about this LOL.
Yes a camera with a speaker can do this.
As I mentioned in this
thread that you didn't reply to my question on did you use these settings:
Audio doesn't follow ONVIF protocol, so you have to find the right protocol in BI.
This is what works for my Amcrest and Dahua cameras with 2-way audio (10 different models):
Where mainstream is:
/cam/realmonitor?channel={CAMNO}&subtype=0&authbasic={AUTH64}&proto=Onvif
and substream is:
/cam/realmonitor?channel={CAMNO}&subtype=1&authbasic={AUTH64}&proto=Onvif
You comment that all cameras that have a speaker support this, but the BI manual said they have reversed engineered, some models, which tells me its not plug and play....being in the software business for 30 years has taught me something about the need to reverse engineer something.
BI Manual
Using a microphone to talk or send audio to the camera is supported for many models in
one of several ways:
Amcrest AD and ASH models are supported using a proprietary DLL and connection.
For many other specific make/model selections (not generic/ONVIF), “talk” has been
reverse engineered. This includes many models offered by Axis, Wansview (and its many
compatibles), Sharx, Trendnet (and its many compatibles), DLink, Hikvision, LevelOne,
AVTech, Dahua, Doorbird, and others.
I went through a suggested list of models (maybe yours) and bought two. Two-way works via the Amcrest app and none of the protocols worked through BI in my setup. I tried all the protocols, four cameras and zero worked. All audio just plays at the NVR, which is BI says happens when it works.
Your above settings are nearly the defaults for BI. It of course be an environmental thing here...at my site.
Care to name a model you use that will allow a .wav files to play on the camera's speaker? Now, that would be a benefit to this forum.
Best,
