If you are connected to the Visualizer wirelessly in Access Point Mode the Visualizer is the end point of your network. There is no routing through to the Ethernet port.

It's possible that you are using a network channel that is already very crowded and busy. Try using another channel or use a network analyzer to find out which of the available channels are less busy.

After you have connected the Visualizer through the pairing procedure you are connected. If you leave the room the connection will stay established. To disconnect there are three possibilities:

1. Hit the disconnect button in the App manually

2. You will be automatically disconnected if your Tablet PC is in standby or the app is in the background for more than five minutes

3. Somebody else pairs with the Visualizer

After you have connected to the iPad wirelessly, the Visualizer is busy decoding the Stream that is received from the iPad. It is not possible to record a session on the Visualizer at the same time. The solution is to record the session directly onto the iPad itself.

After pairing, the Visualizer receives the stream from the iPad that is just white in the beginning. You are no longer working on the camera. Put some content onto the layers and there will be a picture visible. On the output screen you will always see what the audience sees.

You can only integrate the Visualizer camera itself to a certain layer and show it as part of your presentation.

All the other sources are just switched. The iPad content is the Source "Stream" on your WolfVision Visualizer. All the other sources like Memory, External In 1&2 and USB can be shown by switching the source in the app. But they can't be integrated into a layer for the stream.

After you make some annotations the live image of the camera, and also videos will be frozen. The iPad still recognizes your gesture for zooming in and out and will forward these controls to the Visualizer. To get back to the live image you need to touch the layer of the Visualizer or Video and hit the Playback arrow.

Videos that are synced with iTunes to the iPad can only be shown from the native iOS video app. It is not possible to access these files from any other app.

Background to this is that the restriction prevents videos purchased through the iTunes store being copied to any other App or memory space and thereby infringing copyright laws.

In order to put videos or any other content on your iPad we recommend using a supported cloud service.

The destination address and port for the stream are set the same for multiple Visualizers, resulting in a corrupted or incorrect stream as more than one unit tries to send a stream to the same Multicast address. To resolve this change either the destination address or port number. You can do this using either:

1.OSD menu of the unit

2.Web browser OSD of the respective unit

3.vSolution Link OSD menu


1. vSolution Link (formerly known as Connectivity Software)

The current software release for vSolution Link.

If you want to record a session you can choose which codec you want to use for video compression:



It is also possible to record annotations. This can be enabled in the settings.



2. Recording directly to a VZ-9.4F, VZ-9.4L or VZ-C6 System

The recorded video will be stored in the internal memory of the Visualizer, or if a USB stick is plugged in - then directly onto the USB stick. The recorded video is based on the recording settings selected on the Visualizer.



Selecting low frame rate will result in video captured with 7 frames per second, medium at 15 fps, and high frame rate mode at 30 frames per second.

The generated 720p video file is a *.avi file that is compressed with H.264, audio codec is AAC. Please remember that you can only play back Video files on the Visualizer that you have recorded with the Visualizer. The Visualizer cannot act as a media player and play back various different video formats.

3. Recording a video using the vSolution Connect iPad App

When you press the recording icon the colour will change to red, indicating that recording is active. After that the entire session is recorded.

Annotations are also recorded. If you make annotations on a live image from the Visualizer the picture will freeze. To return to the live image hit the layer and touch the playback icon. A pop up will ask you to confirm that you want to drop the current annotation. Anyway – the annotation is recorded as well as long as the recording icon is red.

Scenario 1:

Small meeting room (assuming a room with display or projector and with built-in speakers in the display/projector, HDMI out for video and audio transmission - Setting HDMI Out 'No Mic/Line In' and Line Out 'All sources'

Standalone presentation with recording

The Visualizer is used as the device for recording a video. The internal microphone or a connected microphone solution can be used to capture the voice of the presenter/audience. If a source with audio is selected, the presenter can do a voiceover and will have this mixed audio signal on a stream, a recording, or the line out for an external streaming or recording device.

Limitation:During recording or streaming no integration of vSolution Connect is possible.

Standalone presentation with streaming

The Visualizer is used as the device for streaming a presentation. The internal microphone or a connected microphone solution can be used to capture the voice of the presenter/audience. If a source with audio is selected, the presenter can do a voiceover and will have this mixed audio signal on a stream, a recording or the line-out for an external streaming or recording device.

Limitation: During recording or streaming no integration of vSolution Connect is possible.

Standalone presentation

The Visualizer is used as the device for doing a presentation. If a source with audio (e.g. computer with a video, a stream through vSolution Connect or a playback of a video stored on a USB-stick) is chosen, the Visualizer will loop audio through HDMI and line-out. There will be a small latency of the audio going through the Visualizer.

 

Limitation: During use of vSolution Connect no recording or streaming is possible.

In scenario 1 the Visualizer will do the audio mixing.

Scenario 2:

Lecture room (assuming a room with display or projector and a professional audio system with microphones and speakers; HDMI out for video and line-out for audio transmission - Setting HDMI Out 'Off' and Line Out 'No Mic/Line In')

Standalone presentation with recording

The Visualizer is used as the device for recording a video. The connected microphone solution via line in can be used to capture the voice of the presenter/audience. If a source with audio is chosen the presenter can do a voiceover and will have this mixed audio signal on a stream or a recording.

Limitation: During recording or streaming no integration of vSolution Connect is possible.

For a professional installation the audio signal via line-out is preferable for most installations (many universities have indicated that they do not want audio as part of their HDMIsignal). There will be a small latency of audio going through the Visualizer.

Limitation: During use of vSolution Connect no recording or streaming is possible.

In scenario 2 the professional audio system will do the audio mixing.

 

Audio concept overview (pdf)

By default any pictures taken using the Visualizer/Camera will remain in the internal memory even when the unit is switched off/disconnected from the mains. This behavior can be changed in the onscreen menu so that the internal memory will be erased each time the unit is switched on.

To make this adjustment navigate:

>Onscreen menu:
>Advanced Settings<
>Miscellaneous Settings<
>Erase Memory =MANUALLY (memory is permanent, but can be erased manually in MEM-mode)
                        =STAND-BY (memory will be erased every time the unit is powered on)

Note: WolfVision systems that have this feature are: VZ-8light4, VZ-8plus4, VZ-9.4F, VZ-9.4L, VZ-C6, VZ-9plus3, VZ-9plus, VZ-C122, VZ-123, VZ-C32, VZ-C323, VZ-P18, VZ-P38, EYE-12, and EYE-14. The EYE-12 and some of the older units are slightly different because there is no MEM key on the remote control. MEM mode is accessed using the VIEW key (on some units this key is called ALL).

On older units such as VZ-8plus, and VZ-9, the memory cannot be erased in MEM mode as this functionality is not available. It's possible to erase the internal memory of these devices by keeping the ALL key pressed until an onscreen message pops up.

Dry-erase working surfaces are useful and convenient where making notes and annotations during a presentation. With this accessory, a presenter can write onto, and erase directly from the Visualizer working surface using special whiteboard markers and erasers. This enables the Visualizer to be used as a whiteboard or "digital flip chart". Dry-erase working surfaces are available in 2 piece packs.

XXL size dry-erase working surfaces are also available for use with Ceiling Visualizers and EYE Cameras - giving an even larger writing area!

Important

Only whiteboard markers and not permanent or non-permanent markers should be used with dry-erase working surfaces.

Storage of new dry-erase working surfaces

Dry-erase working surfaces can be stored for up to 12 months in their original packaging - see date stamp on packaging.

Ideal storage conditions: +20°C (68°F) at 50% relative humidity.

Do not bend the replacement working surface foils.

We do not manufacture height adjustable tables. Please contact your furniture supplier for more information on suitable platforms.

You cannot show .ppt slides directly from a USB stick, but an acceptable workaround is to save each slide as a JPEG in advance, and then the presentation can be displayed. Note: any animations cannot be shown as the JPEG is only a still image for each slide.

This feature is available for VZ-8light4, VZ-8plus4, VZ-9.4F, VZ-9.4L, VZ-C6, and EYE-14 devices.

You can lock the on-screen menu of VZ-8light4, VZ-8plus4, VZ-9.4F, VZ-9.4L, VZ-C6, and EYE-14 devices if required.
