4.Audio/Video (AV) Functions

Once a call is connected, the FieldView Device can send an AV media stream to the FieldView Application software client.

4.1. Turning the Video Stream On or Off

To start streaming real-time video to the FieldView Application software client, press the green Stream button on the top of the FieldView Device. Press the Stream button again to stop streaming. This does not disconnect the call; the stream can be started and stopped as often as desired within the current call.

This sends a live audio/video media stream from the FieldView Device to the FieldView Application software client. The stream will continue as long as the call is connected (i.e., neither user hangs up the call), or until the Operator or FieldView Application user selects an option to stop streaming.

4.2. Setting the Subject Audio Source

The FieldView Device provides two audio channels: one for subject audio and one for VoIP telephone communication (see page 9).

The Subject audio—the audio being captured and streamed with the video— can be captured by the FieldView Device’s built-in microphone or from an audio source connected to the Line-In port. This allows the FieldView Device to capture and stream high-quality audio that is time-synchronized with the video. The green Stream button also starts and stops streaming of Subject Audio, just as in video streaming described above.

To set which source will act as the Subject Audio Source:

1.From the standard Viewfinder display window, press the Display button three times (or until the Main Menu appears).

2.Tap the Configuration option with the stylus to display the Configuration screen.

3.Display the Audio tab. This tab allows you to control speaker and microphone volume, and to select the Subject Audio Source.

4.3. Using S-video

When using a FieldView Device model which has S-video input, the S-video source must be attached to the FieldView Device and powered before setting the video source to S-videoin the Configuration Video tab. Otherwise, the video stream being sent to the FieldView Application may not synchronize and may not be aligned to the frame. If synchronization does not occur, correct it by setting the FieldView Device’s video source to Internal and then back to S-video. See Configuration on page 18 for more information about configuring the FieldView Device video.

4.4. Turning the Front Light On or Off

The light on the front of the FieldView Device can be used to provide extra lighting in dim lighting situations. Use the right cursor pad button to toggle the light on or off. Note that if the FieldView Device is displaying a configuration or directory screen, the Light button

operates as a right arrow key.
