First, make sure that you are using the latest version of WebCam Monitor. To download the latest version, visit:
https://www.deskshare.com/wcm.aspxTo detect only noise, you must disable motion detection. To do so, point to the Tools menu and click Options. Click the Monitoring tab and under Motion Detection, uncheck the "Enable Motion Detection" option.
By default, WebCam Monitor selects the first audio device for noise detection. You can change the devices from the drop-downs placed above the preview window. The Add Camera Wizard from the File menu can also be used for changing audio and video devices.
Although the noise will trigger Video/Audio Recording but it will not record the sound itself. We are working on a pre-buffered recording scheme that will enable WebCam Monitor to record video and audio data that ocurred before the trigger.
To monitor the camera remotely at a scheduled time, simply click "Start Streaming" from the toolbar. Then using the Device Scheduler, set WebCam Monitor to start at 12:00 a.m. and stop at 6:00 a.m. When the devices start, streaming will automatically start transmitting video/audio streams. Next you can go to your remote PC and view the video/audio stream by typing in the URL given to you by WebCam Monitor.
