Requirements for listening to audio

To listen to incoming audio from the cameras in your XProtect VMS through a mobile device, you must have:

• A microphone attached to a camera.

  When a camera in your surveillance system has a microphone attached, you can play audio without any additional settings needed. The audio icon on the camera toolbar shows whether the audio feature is available.

• Sufficient user permissions.

  Access to the incoming audio feature may be restricted depending on your user permissions. Ask your system administrator if in doubt.

• HTTP or HTTPS with CA certificate connection.

  If you want to use an HTTPS connection, a digital certificate from a certificate authority (CA) must be installed on your XProtect Mobile server.

  CAs issue digital certificates that verify the identities of users and websites that exchange data on the internet. Examples of CAs are companies like Comodo, Symantec, and GoDaddy. For detailed information about certificates, see the topic about enabling encryption in the guide about certificates.
