I am trying to send a .wav file to a Hikvision camera to make alert voice at camera. The camera is activated for twowayaudio as below.
atic@ubuntu:~$ curl --digest -X PUT admin:[email protected]/ISAPI/System/TwoWayAudio/channels/1/open
Twoway audio is activated with ourputs as below
<?xml version="1.0" encoding="UTF-8" ?>
<TwoWayAudioSession version="2.0" xmlns="http://www.isapi.org/ver20/XMLSchema">
<sessionId>27e09003</sessionId>
</TwoWayAudioSession>
Then when I send audio file
atic@ubuntu:~$ curl -H "application/binary" -X PUT -d @alert1.wav admin:[email protected]/ISAPI/System/TwoWayAudio/channels/1/audioData
