Speak action independent volume
New
Briefly, my use case: Using DW Spectrum in a jail with two monitoring stations. I set a Perimeter Intrusion Analytics Event so that when a car pulls up to be let in to our bays, the Spectrum client speaks "Sally Port" so that the person, who is doing ten other things at the same time, knows to look at the monitor. The plan was to use the same types of events for many of our doors, which require a person to buzz you in.
The Speak part works great, except for its speaking volume is tied to the main volume of Spectrum. I keep the main volume muted on their stations, because it is just too much noise for the stations to be playing audio from whatever camera they last clicked. I'd actually prefer guards not have access to the audio at all, but that doesn't seem to be an option.
My current plan is to have my command line launcher launch two windows. The main one that they will use to watch cameras on, which will be muted, and a second instance of the app that will have a default layout, using a background image with instructions to leave it alone. This instance will stay on max volume to actually do the Speak events.
My question is, is there a way to set each instance's volume via the command prompt or by other means? Even better, I'd love to just disable audio on the main instance they use. For the one with audio, I could just make a user that can't see any cameras. Any ideas?
Thanks!

No, I was never able to get it to work right. Since I can't control the volume from the command prompt, I can't launch one window muted and a hidden one at max volume, so that it can speak what is happening. As a temporary solution, I got a little hackey. I have an ADAM I/O board connected to a little voice playback module that plays from a selection of prerecorded messages when activated. This solution is definitely not ideal, but we're making it work.
If I were to have a suggestion for a future version of NX Witness, it would be more fine-grained control over the audio and volume. For example, I'd like the option to give/remove access to sound from video. I don't want our live monitors to be able to hear audio, but we do want to preserve it in case needed. Also it would be great to be able to have a --noaudio flag for launching via command line.
Thanks!

Hi Johnathan Powell,
Noted. Currently, I don't see a solution for the challenge you're facing, however, I have seen changes in the user roles which define if a user can use audio or not. Unfortunately, I don't know the ETA for this feature.
I'll move this topic to our Feature Feedback section, so our product team can read along and might be able to provide some insight in this matter.
Also, our design team follows the topics in the Feature Feedback section to collect feedback about specific features, and they likely benefit from your comments as well.
