Nureva HDL410 – Best Practice for Camera IntegrationDirect Integration Before installing a camera steering and switching solution to integrate with your Nureva audio solution, we recommend you refer to the below information and important links.You can find comprehensive instructions on installing and configuring a Nureva / camera solution on the Nureva Support site.This article gives guidance you may not find online, plus some Top Tips that we have picked up.Understand the customer requirementsNureva can support both camera steering (tracking/switching presets), and camera switching (changing to different cameras).It is important to have a view of the customers room, and understand which areas of the room need to be covered by a camera.  From this, you can determine the number of cameras required and the fields of view.If you have any queries about this, please contact Ascentae for advice.  We can even offer a full pre-installation consultancy service to help with this.Understand the limitations of the technology – HDL300 / HDL310         When integrating with a HDL300 or HDL310, you have a single sound bar – and so only one point of reference.  The information passed to the camera controller is based on the central point of the sound bar.  This makes it an ideal solution for azimuth presets, with a single camera mounted in line with the centre of the sound bar.Typically, up to 8 presets can be configured, each covering 22.5° of the room.The same is true if you have the legacy Dual HDL300 system.  The reference point for camera tracking will be the centre point of the primary sound bar (plugged into port 1 on the Connect Module).  The 2nd sound bar is not used for camera tracking).If using more than one camera, the best position for the cameras is either side of the sound bar, each covering half the room and using 4 presets.Understand the limitations of the technology – HDL300 / HDL310The HDL410 has 2 sound bars and when correctly positioned in the room, they can deliver accurate X,Y coordinate information to the camera controller.  Depending on the sophistication of the camera controller, it can interpret those coordinates in different ways.                Select appropriate camera and steer to coordinate location                Select appropriate camera and steer using presets                Select appropriate camera and switch to pre-defined zoneNote:  Not all camera controllers support all these modes.  Refer the camera vendor documentation for details.Camera zoning is covered in detail in a separate knowledge base article.Choosing the correct cameraNureva have created a suite of API calls which different camera providers have utilized to integrate with the Nureva devices.  Currently these are Aver and Lumens, plus drivers and sound tracking modules by Crestron and Extron.Typically, each camera vendor has created a software camera controller (in some instances it may be a hardware device).  Nureva confirm compatibility with the camera controller.  However, not all cameras from a specific vendor will be supported on the controller software.  It is the responsibility of the integrator to confirm compatibility of cameras and camera control solution.Make sure you check the focus length / zoom capabilities of the proposed camera.  If you are installing in a large room, the camera should be able to zoom and focus clearly on the furthest participant.Currently supported camera drivers are as follows.Note that camera switching is not supported by PTZApp 2 (single camera only)Note that camera switching is not supported by CamConnect Lite (single camera only)Cameras that support preset recall and have a Crestron module can support sound location data.Cameras that support preset recall and have an Extron driver can support sound location data.Positioning of the Nureva Sound BarsFor the HL300 / HDL310 remember that the camera reference point is the centre of the sound bar.The ideal position for the sound bar is above the screen – allowing sufficient clearance for the audio to be reflected off the wall into the microphones.It is important that there is no obstruction underneath the sound bar as this will degrade audio quality and cause inaccurate sound location data.To ensure best audio performance, measure how far your screen sits from the wall, and mount the sound bar so the bottom is 1.5 x this distance.E.g.  if you screen sits 10cm proud of the wall, the bottom of the sound bar should be 15cm from the top of the screen.Refer to the Microphone clearance requirements guide for more detailshttps://support.nureva.com/docs/installation-hdl300-microphone-clearance-requirements-and-recommendations-2We recommend that cameras are mounted underneath the screen where possible, but if underneath HDL sound bar, allow at least 6” (15cm) clearance from the top of the camera to the bottom of the sound bar.Available ResourcesSupported camera solution

reflectionsCameras are dumb and can easily be confused by reflections in windows.Be mindful of setting presets that can catch reflected images, or setting the camera to track in areas where windows will reflect if it’s dark outside.Ideally, curtains or blinds will not only avoid this issue, but have the additional benefit of reducing echo and reverberation in the room and so improve performance of the HDL device.If in doubt, ask AscentaeWe are here to help.  Please ask if you need any guidance, or would like to engage us to do a consultation on HDL and camera integration.

Solution Overview Multi-Camera SolutionFlexible meeting spaces require flexibility solutions to maximise performance.  A front facing camera may be suitable for regular meetings, but for presentation or teacher / student interaction, additional AV equipment should be considered. There are a number of solutions on the market which offer camera switching, but these can dramatically increase the price of the solution for minimal additional performance.For many spaces, all that’s required is multiple camera, and the ability to switch between them easily.  The addition of a ReThink AV auto switching matrix allows both the in-room PC and guest laptops to access the AV and simply switch to the desired camera within the UC client (Teams/Zoom etc). For additional ease of use, the matrix can be programmed to switch sources on a keyboard shortcut or integrated into a room control system. Up to 5 USB peripherals can be configured and dual screen output is fully supported to allow maximum performance and flexibility. Optionally, wireless sharing can be integrated with the in-room PC.  We recommend AirServer or Mersive solutions, or for customers who want to use a wireless dongle, the Maxhub WB05 provides wireless sharing without the need to install software or connect to a wifi hotspot.Key Benefits- One-touch join of Microsoft Teams meetings- Easily switch between USB peripherals within your UC client, via keyboard shortcut or via control system- Up to 5 USB peripherals can be installed- Dual screen support- Bring Your Own Meeting support connects screen and peripherals.  Host the meeting on your computer.- Auto switching to your computer as soon as you plug in- Single USB-C connects your computer for video, audio, data and network*.  Plus, it charges your battery!*Wired network connection required to ReThink switch. ·        Core Components-  Dual Maxhub ND65 CMA 65” displays ·        -  Huddly C1 All-in-one camera / mic / speaker system ·        -  Additional cameras (RocWare RC821 shown) ·        -  Additional audio system (if required – Nureva - HDL310 shown) ·       -  ReThink AV MatrixRAV-MS-4x2DLHU-Tx/Rx - ReThink active USB-C cableOptional Components for wireless sharing-  Mersive POD v4- AirServer Connect 3- MAXHUB WB05 + buttonThis example includes dual screens and a MAXHUB XCore Pro MTR.A Huddly C1 is provided for front of room camera and meeting audio.When switching to presenter mode, the RocWare RC821 PTZ camera is mounted at the rear of the room to capture the presenter.A Nureva HDL310 is included to provide whole room audio in presentation mode.A wireless keyboard & mouse are installed to allow quick switching between setups.

Nureva HDL410Best Practice for Camera Zoning Before installing a camera zoning solution to integrate with your Nureva audio solution, we recommend you refer to the below information and important links.You can find comprehensive instructions on installing and configuring a Nureva / camera solution on the Nureva Support site.This article gives guidance you may not find online, plus some Top Tips that we have picked up. Understand the customer requirementsWhen integrating the HDL410 for camera zoning, you can install up to 3 cameras covering different areas of the space.A typical use case may be a presenter / audience configuration, with a camera facing the front of the room for presentations and another 1 or 2 covering the audience.We also see this in use in larger meeting rooms where a single camera struggles to cover the entire room.If you have any queries about this, please contact Ascentae for advice.  We can even offer a full pre-installation consultancy service to help with this. Understand the limitations of the technologyThe HDL410 will deliver X,Y co-ordinates to an Inogeni Cam230 camera switcher, enabling it to switch to a camera relating to a specific zone in the room.It is then a function of the camera to Pan, Tilt and Zoom within that zone.  Additional camera software may be required to enable this.Zones cannot overlap – or be too close together – as this could result in the cameras switching incorrectly.Both the HDL410 and Inogeni CAM230 MUST be connected to a network and the HDL410 MUST have internet access and be enrolled in Console Cloud.Choosing the correct cameraThe Inogeni CAM230 allows up to 3 cameras to be integrated – 2 USB and 1 HDMI.  Alternatively, a 3rd USB camera can be supported using the Inogeni U-CAM convertor.This gives great flexibility and allows different types of camera to be used depending on the application.For example, a framing camera (such as Huddly L1) could be used to accurately frame a presenter as they move around the front of the room and a PTZ camera could be used for the audience.  A 3rd, static camera could be trained on a whiteboard to capture the content when someone is writing on the board.Positioning of the Nureva Sound BarsIt is strongly recommended that the 2 sound bars are mounted on opposite or adjacent walls to provide the most accurate sound location data. As with all installations of Nureva sound bars, ensure the sound bars are not mounted directly above a screen or other obstruction.We have found that any obstructions underneath the sound bar can cause problems with accurate sound location data, so ideally they should be mounted with nothing underneath them.  However, if this is not possible, refer to the Microphone clearance requirements guide for details on how to install.https://support.nureva.com/docs/installation-hdl300-microphone-clearance-requirements-and-recommendations-2   Creating camera zonesBe aware that unless your room is acoustically perfect, X, Y coordinates will always have a margin for error.Ideally, make your zones generous and leave at least 50cm gap between them.  If zones are too small, or too close together, in room echo can cause inaccuracies and cause the camera to switch unnecessarily.It is generally better to have the system revert to the default camera than to focus on the wrong person or continually switch cameras if someone is sat on the edge of 2 zones which are too close together.Watch out for reflectionsCameras are dumb and can easily be confused by reflections in windows.Be mindful of setting presets that can catch reflected images, or setting the camera to track in areas where windows will reflect if it’s dark outside.Ideally, curtains or blinds will not only avoid this issue, but have the additional benefit of reducing echo and reverberation in the room and so improve performance of the HDL device.If in doubt, Ask AscentaeWe are here to help.  Please ask if you need any guidance, or would like to engage us to do a consultation on HDL and camera integration.Available ResourcesInogeni Integration FAQ’s - https://support.nureva.com/docs/technical-faqs-hdl410-and-inogeni-cam230Inogeni Integration Guide - https://support.nureva.com/docs/integration-guide-hdl410-and-cam230

During compatibility testing, we have identified the following potential issues when using all-in-one screens and USB switchers.Outline of issues When using a USB switcher with active cable, it is possible to exceed the maximum number of USB Tiers (levels / hubs)The total permitted number of USB tiers is 7.  This is set out in the USB standard.  In theory, this limitation shouldn’t be reached, but as laptops develop and AV installations make greater use of USB devices, it is possible to exceed the limit.In our tested scenarios we used 2 different makes of Windows 11 laptops, 4 switches and 4 screens.- A laptop computer typically users 2 or 3 tiers, depending on complexity of internal USB.- A USB Switcher uses 2 tiers- An Active USB Cable uses 2 Tiers- An All-In-One screen with built-in camera, speakers and microphone will use 2 or 3 TiersSymptomsIf the total number of USB tiers is exceeded, Windows 11 machines will typically display an error message ‘USB device not recognised’ or ‘Maximum USB Hubs Exceeded’.  Occasionally, a “silent failure” will occur and no error is displayed.  However, in Device Manager, a USB Hub will be shown in fail state.USB devices on the All-In-One screen will not be accessible via the USB switch (microphone, camera, speakers and touch back). Fig 1.  In this scenario, the laptop will not see any of the peripherals on the AIO screen  How to determine if you have this issueWhilst you can check within Windows, we downloaded a USB Diagnostic tool to provide more detailed information.  There are lots available, but we used the Liteware USB20 Configurator app. Potential WorkaroundsBecause this is a fundamental restriction of USB architecture, there is no ideal solution.  However, options may include:Option 1.Using a passive USB connection to the laptop (USB-C
