Nureva HDL410
Best 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 requirements
When 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 technology
The 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 camera
The 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 Bars
It 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.

Creating camera zones
Be 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 reflections
Cameras 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 Ascentae
