INTRODUCTION 

VK2 IP cameras equipped with audio line-out can utilise a standard software feature to play short pre-recorded announcment files (max of 3) upload to the camera. Audio file playback can be triggered by camera inputs;


  • Motion
  • Alarm-in
  • Manual-trigger
  • Tamper
  • Timer


File format used is G.711u and Vista’s VK2-Client software contains a Windows applet to record your announcment on a Windows PC with a microphone. Freeware utilities may also allow conversion from .wav file.



Note: Audio file playback and control is simply performed autonomously and locally on\by the camera and not in conjunction with your Viper NVR etc. However, by “doubling-up” the setting we show you below, a simaltaneous “Alarm Out” can be sent from the camera to your Viper NVR


PROCEDURE

We assume your Vista VK2 IP camera and audio path\amp\sounder are already correctly installed and tested.

First, download the Vista VK2 ARecorder applet to your Windows PC and record your announcement file;


  • Open web browser and visit the link below;
