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.

Product Code: INT1-POE-DESKGoBright have released a PoE adapter for their Interact device. If you can't power the device over the 230V mains adapter, PoE is now here! As you can see, it comes with 3M adhesive to fix the device to a surface.This is the connection that needs to be plugged into the Interact device:You then have the expansion box:  Note: A network cable is not suppliedWe tested the device on the 12th of June 2024, using a "dumb" NETGEAR PoE switch and an Interact running Application Version 1.6.1. If you're using a managed switch, please ensure PoE is enabled on the port(s) that you connect the Interact(s) to. Some further photos that might help plan your installation:Important: When using Interacts, you must configure your firewall to allow outbound traffic over MQTT (port 8883) over TLS. NTP and DNS must also be correctly configured for the device to communicate with the GoBright platform. The firewall configuration can be found here.Please contact support@ascentae.com for any help.

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
