    Audio playback API?

    Hello! Does anybody know how to play audio on the Uniview cameras with a speaker? I mean manually with curl or something like that, not from a web interface. I looked at the api documentation someone posted here and the only thing I can find is /LAPI/V1.0/Channels/0/Media/Talk which returns just...

    No audio in UI3 on iOS

    Hi everyone, we're running UI3 version 5.6.3.7 which has been great. However, my fiancée pointed out to me today that there's no audio when viewing cameras live in UI3 or when viewing alerts on her iPhone 14 Pro.

    Microphone input wiring question and Bluetooth receiver for DS-2CD2147G2-SU

    Hi there I’m new here and I’d really appreciate some help. I have a audio enabled camera and I’d like some advice on wiring. I thought I would be able to make a female 3.5mm jack to plug my mic into the IP camera. It’s not a Hikvision mic, it’s a lapel mic with its own power. I also plan to...
