In this article we will discuss how to setup and use Rhombus's Audio Gateway:
- Console Usage
- Mobile App
- External Inputs
Enable Audio Listening and Recording
After registering the audio gateway the first action to take within the console is to enable audio listening and recording.
Navigate to Settings -> Account and toggle the "Allow Audio Listening & Recording"
Assign Audio License
To enable the Audio Gateway to record audio and cloud archiving, you need to enable the Audio Gateway Enterprise license for a given device.
Navigate to the settings menu and click on the License & Features button. From there you will see the Audio Gateways tab in the upper left next to Cameras. Once here you need to apply the Enterprise license to the desired device(s) by clicking the blue manage button in the Enterprise area of the License Summary section. Once selected, hit save. After, click the manage button on the far right of device you just added a license too. When the modal pops up select the Audio AI Analytics toggle and any cloud archiving wanted and then hit save.
See the below GIF to view the entire process.
Note: If you do not see Enterprise licenses in your account, please contact your Rhombus sales representative or our support team (firstname.lastname@example.org)
On the audio gateway page, you can listen to the audio capture synched with the camera footage. At the bottom of the footage you can dive into audio events by clicking on the seek points in the timeline (below in teal and red).
Changing Location and Device Name
At the bottom of the page you can edit the name of the camera (circled in black), change the address (circled in blue), and can unregister the camera (circled in red).
Changing Audio Settings
Clicking on the Audio Controls button within the device player view (below) will bring up the options that manipulate the device.
Configure to your setup needs by selecting the mic/speaker sources if you are utilizing the external input/output.
Note: Acoustic Echo Cancelling (AEC) is a filter and is based on an adaptive algorithm that changes this filter to model the acoustic path. The output of the filter is then removed from the acoustic path signal, in order to create a “clean” signal output. Any echoes in the call environment are removed.
AEC only works with internal mic and speaker
Changing Assigned Cameras
In the upper left corner of the player view select the drop down next to "Assigned Cameras"
From here you can select what cameras you want to associate the device to.
Listening in to the Device
Hovering over the audio button (below in red) will allow you to toggle the listening volume of the device. Make sure your volume is up on your machine to listen in!
Speaking Through the Device
Hovering over the microphone button (below in red) will allow you to speak through the device. Click and hold this button to then speak through it. Make sure the internal speaker volume is up so people around the sensor can hear what is said.
To navigate to the audio gateway simply select the gateway from the devices tab (far left icon) and select the gateway of interest. Below if a demonstrative GIF of this process:
Below is the main screen of an audio gateway. Here you can have the ability to listen to the gateway on your mobile device by toggling the 'Playing/Muted' button on the top left below the name and location. Also, you have the ability to speak through the gateway by pressing and holding the 'Press and Hold to Talk' button, similar to a walkie talkie. You can also assign the gateway to a different camera, and listen to the audio events captured by the gateway through tapping on seek points in the timeline.
To create a policy for the A100, navigate to Settings -> Policies -> Audio Gateway device tab
You can create loudness polices (below) to be alerted when the sensor detects a high audio level.
To assign the policy to a sensor click on the "Assigned Sensors" tab right of the "Audio Gateway Alert Settings" seen in the above screen shot. When there, you can add a device by clicking the "Add Device" button and then select the device you want to add the policy to.
Note: LUFS are units of audio loudness. The acronym stands for Loudness Units Full Scale. Essentially, it's a standard way of measuring audio that blends the perceived loudness from human hearing and the true intensity of an audio signal together.
Below shows the connection points for the A100. Connections include:
- External Speaker Input
- External Microphone Input
- PoE Input
To unregister an audio gateway, navigate to the audio gateway page (Devices->Audio Gateway->one of interest), click the 'Unregister' button on the bottom in the Unregister Gateway section.
Next, following the prompts just type in 'DELETE' in the text box, and then click the 'Unregister' button.
