INOGENI CAM230 integration guide — Nureva App and HDL410

As classrooms offer more remote learning options and workplaces become more flexible, the demand for multiple cameras for videoconferencing is growing. The Nureva^® HDL410 system integrates with the INOGENI^® CAM230 camera selector to enable automatic camera switching in multi-camera rooms.

This integration equips multiple cameras with switching capabilities based on camera zones, improving the room’s overall camera coverage and the experience for remote participants. Camera zones are set up using the Nureva App or Nureva Console cloud. This article focuses on setting up the integration using the Nureva App.

Step 1: Establish placement, connections and network access

System placement

For the HDL410 system to provide the most accurate sound location data, Nureva recommends the microphone and speaker bars be installed on opposite or perpendicular walls. This positioning produces accurate X and Y data.

Recommended installation positions are shown in the diagrams below.

Hardware connections

Connect the HDL410 and CAM230 as shown in the connection diagram below.

Network access

Data is exchanged between the HDL410 connect module and the CAM230 to facilitate camera switching. The connect module and CAM230 must be connected to the same network for the data exchange to happen.

INOGENI recommends reserving an IP address on the network for the CAM230. Using the reserved IP address will help with the initial setup and maintain communication between the CAM230 and the HDL410 connect module.

Step 2: Update CAM230 firmware

Important: The CAM230 should use firmware version 2.10 or later for this integration. Using firmware versions earlier than 2.10 may have unexpected results.

INOGENI offers a web portal for the configuration and management of the CAM230. The firmware is updated using this web portal and a downloaded file.

The CAM230 and computer must be on the same web portal network to make a connection. An alternative option is to connect the computer directly to the CAM230. If the web portal or computer does not recognize the CAM230, try the following:

• Ensure the CAM230 is assigned to a reserved IP address on the network.

• Confirm the computer and CAM230 are connected to the same network.

• Power cycle the CAM230.

• Check the Ethernet cable connections.

• Try different Ethernet cables.

• Check the USB cable connection between the computer and CAM230.

Logging in to the CAM230 web portal

1. Access the web portal by entering the IP address 169.254.10.10 into a browser.

2. Complete the login with username admin and password admin.

3. The portal will open showing the Status tab.

   • The information shown under General includes the firmware version and the CAM230 IP address.

4. Check the firmware version in the Status tab.

5. If the firmware is earlier than version 2.2, go to the CAM230 resources webpage.

   • Go to the Firmware section at the top of the page.

1. Select the System tab.

2. Go to the Security section at the top of the page.

3. Press the Get current REST API access token button.

4. A new web page will open and show the REST API access token.

   • Copy the token from this page.

5. Press the back button on the browser to return to the CAM230 web portal.

Step 4: Connect to the Nureva App and update HDL410 firmware

Connect to the Nureva App

The HDL410 system must be connected to the Nureva App before setting up camera switching.

1. Open a browser and enter the IP address for the device into the search bar.

2. When prompted for a password, enter the HDL410 enrollment code and click Continue.

3. The app will advance to the device management page.

Get started with the Nureva App

Updating the HDL410 firmware

To ensure optimum audio quality and access to the latest features, the HDL410 firmware must be current. An update button will be available in the Nureva App if a firmware update is required. Advance to the next step when the HDL410 firmware is up to date.

Step 5: Enable camera switching integration

Note: INOGENI recommends reserving an IP address on the network for the CAM230. Using the reserved IP address will help with the initial setup and maintain communication between the CAM230 and the HDL410 connect module.

1. From the Home page dashboard, open Integrations.

2. Select Camera switching and enable it by moving the toggle to the right.

3. Enter the IP address or the hostname.

4. Enter the Port number (Port 443 is the default and will apply to most integrations).

5. Copy and paste the REST API access token that was generated in Step 3.

6. Press the Connect button to connect to the CAM230.

After the connection is complete, open the Coverage map. If the CAM230 integration has successfully been set up, camera switching controls will be available.

If the camera switching controls are unavailable, check that the IP address and REST API access token have been entered correctly. Also, confirm that the HDL410 and CAM230 are switched on and connected to the same network.

Step 6: Confirm placement

The HDL410 system generates a coverage map showing the system’s placement. The blue circles on the coverage map indicate where sound location data is being generated within the room. The system placement must be shown accurately on the coverage map to ensure accurate camera switching.

Confirm system placement

The coverage map should show the positioning of the microphone and speaker bars as they are in the room. If the coverage map placement and the actual placement do not match, the system should be recalibrated. Sound location data may not appear if sound is not generated in a room.

The following steps are taken to perform recalibration through the Nureva App. Make sure there are no audible sound sources in the room other than normal ambient noise (e.g., no music playing, no people talking).

1. From the Home page, open Settings.

2. Select Audio processing.

3. Select Recalibrate and then Start.

When the calibration signal stops and the indicator lights return to a normal state, the recalibration is complete. The HDL410 system placement on the coverage map should now represent the actual placement in the room.

Step 7: Create coverage map zones

A zone defines an approximate area within a room. The data to map each zone, as well as the indication of when a sound is detected within each zone, is sent to the CAM230 to facilitate camera switching.

Creating a zone

1. Press Create zone in the side menu on the coverage map page.

   • A zone will appear at the center of the coverage map.

2. Drag the zone within the coverage map to the required location in the room.

3. Adjust the zone to the required size using the drag handles.

4. Press Apply to save the zone.

Editing the zone name

Zone names can be edited by selecting the T icon in the editing bar above the zone. Naming the zone to associate it with the camera’s input and coverage can make it easier when configuring camera switching. For example, if Camera 1 is focused on the audience, use Audience for the zone name.

Deleting a zone

Zones can be deleted by choosing the zone from the coverage map and then selecting the trash can icon in the editing bar above the zone.

Testing zones

Zones can be tested by speaking in each zone area within the room. It is recommended the tester talk for at least one minute while moving to all the edges of the zone being defined. As sound location data is captured and displayed on the coverage map, it will help confirm the zone position and size. The sound location data refreshes every minute.

Adjust the zone size and position if required. All sound data above 45 dB will be shown on the coverage map but only data above 60 dB for a specified length of time will be used to initiate a camera switch. A zone cannot be applied if:

• It’s overlapping with another zone.

• It doesn’t have a name.

• It has a name that’s being used for another zone.

• Its name exceeds 50 characters.

Step 8: Configure camera switching settings

Assigning cameras to zones

• Select a zone to view the zone tools. Click the camera icon to open a menu of connected cameras. Assign the required camera to the zone and click Apply.

Default camera

• Open Camera switching on the coverage map to define the default camera. Select a camera from the Default camera menu. This is the camera that the CAM230 switches to whenever voices are not detected.

Adjust camera switching trigger timing

The INOGENI CAM230 activates camera switching when it detects sound in a specific zone for at least 1 second. If no sound is detected, it switches to the default camera. The default time for triggering the switch is 1 second and can be adjusted to match the room’s needs.

To adjust the timing of the camera switching, open Camera switching. Then change:

• The minimum sound duration to trigger a camera switch.

• The maximum time to wait before switching to the default camera.

Indication of triggered camera

When camera switching is configured, commands will be sent to the INOGENI CAM230 to use a specific camera based on the sound location data and trigger timing. The camera triggered by the HDL410 will be underlined on the coverage map to indicate which camera should be active. As sounds occur in the room, the active camera underline will change between cameras as they are triggered.

In the example above, Camera 1 (Presenter zone) is underlined, indicating which camera the CAM230 has triggered.

If a camera is underlined on the coverage map but the camera is not being used, the CAM230 is either not receiving the switching command or the automatic switching has been turned off. To restore switching, troubleshoot the CAM230 connection and ensure automatic switching is turned on.

Turning off automatic switching

To turn off automatic camera switching, press the input button on the CAM230 for the corresponding camera. Automatic camera switching can be resumed by pressing the same input button.

Automatic camera switching can turned on and off during a conference call. When the conference is over, the CAM230 will return to automatic switching.

CAM230 status lights

The CAM230 has status lights on the front of the device. These lights help determine the status of the device and can be used to help troubleshoot.
