How to send text to voice messages to my 2 way audio camera in HS4. Any plug-ins? Anyone has experience doing it and willing to share? Pls. help. Camera is SV3C brand 5 Mp camera that supports "ONVIF Profile S" , "RTSP" and "P2P" protocols and the audio codec is G711.

Thanks

...following... I have a camera in my garage that has audio and would like to have it speak "Recording in progress" or something to that effect.
