Requirements for listening to audio

To listen to incoming audio from the cameras in your VMS system 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 rights

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

• HTTP or HTTPS with CA certificate connection

  If you want to use HTTPS connection, a digital certificate from a certificate authority (CA) must be installed on your XProtect Mobile server. You cannot listen to audio through your mobile device if you use a self-signed certificate.

  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. To learn how to edit a certificate on the XProtect Mobile server, see the administrator manual of your surveillance system.
