You can designate an input that already exists in a Broadcaster cluster to be added as a Source in ZEN Master for monitoring purposes only. This is done by selecting **Monitor Only** in the **New Source** menu.
In this case, the Input already exists in the Brodcaster within the **Ingest Cluster**. The **Origin Device** is unknown and not managed or monitored by ZEN Master. The stream can be Pushed to or Pulled by the Ingest Cluster, as manually configured in the Input configuration of the Broadcaster. The steam can use any protocol that is supported by Broadcaster, including protocols that are not supported in ZEN Master (e.g., RTSP).
:::hint{type="info"}
This behavior is uncommon to other Sources because in this case the input on the Broadcaster must already exist, while in other cases, for example, after configuring the Source in ZEN Master, ZEN Master will create the input on the Broadcaster.
:::
- **Multiple inputs** - You can select several inputs from a single Broadcaster to simultaneously create a new Source in ZEN Master for each input.
The following procedure describes how to add a Monitor Only Source in ZEN Master. In addition, an explanation of each of the configuration parameters is given in the table below.
**To add a Monitor Only Source:**
:::::WorkflowBlock
:::WorkflowBlockItem
In the main navigation, click **Sources**.
:::
:::WorkflowBlockItem
Click **+ Add**.
The **Create New Source selection** window is displayed.
:::
:::WorkflowBlockItem
Click on **Monitor Only**.
The **Create Monitor Only Source** window opens.
:::
:::WorkflowBlockItem
In the **Info** section, in the **Name** field, leave blank. The name of the Source will be the same name as the Broadcaster Input.
:::
:::WorkflowBlockItem
In the **Tags** field, select one or more of the predefined Tags from the drop-down list.
Tags are used for access control. By selecting a Tag, you are relating this Source to that Tag. Tags are associated with certain roles (through the Users & Roles screen), and roles, in turn, are associated with users and user groups. If you would like to create a new Tag, see [Creating a Tag](docId\:YpM9tw81ap6nq8sTKv4Rd).
:::
::::WorkflowBlockItem
In the **Events Configuration Profile** field, select from the dropdown list the profile that you would like to apply to this Source. By default, the Default profile is applied.
:::hint{type="info"}
*Events Profiles* consist of a series of rules that determine precisely how various types of Events are logged and what results they trigger.
:::
::::
:::WorkflowBlockItem
The Source's location is used to represent it in the proper position in the Map display (see [Maps](docId\:sFZM6JvoRvuigo7X0dNUE)). By default, the location is determined automatically based on the Source's IP. If you would like to manually set the location of the Source (Optional), use the following procedure:
1. Click on the **Edit** icon next to the **Location **field.
A search box is shown below the **Location** field.
2. Enter identifying info for the location (e.g. street address, zip code, coordinates).
Search results are displayed below the search box as you type.
3. Click on the desired location.
The selected location populates the **Location** field.
:::
:::WorkflowBlockItem
In the **Input** section, in the **Broadcaster** field, select from the drop-down list the Broadcaster on which you have created the Input(s) that will be monitored by ZEN Master.
A list of available Inputs on that Broadcaster is displayed.
:::
::::WorkflowBlockItem
Select one or more Inputs by clicking the **+** button for the desired Input.
:::hint{type="info"}
Each input that is selected creates a **separate** Source in ZEN Master
:::
Selected Inputs are shown above the **Filter** box. (You can remove an Input by clicking the **-** button for that Input).
::::
:::WorkflowBlockItem
In the **Configuration** section, select the **Alert on PID changes** checkbox if you would like to generate email notifications whenever a PID change is detected.
:::
::::WorkflowBlockItem
Select the **Log SCTE-35** checkbox if you would like to log SCTE-35 markers for this stream.
:::hint{type="info"}
- To log SCTE-35 markers, SCTE-35 needs to be enabled both on the Ingest Cluster and on the Source configuration.
- SCTE-35 logging is only available for v13.1.40262+ Broadcasters.
:::
::::
:::WorkflowBlockItem
If **Log SCTE-35** was selected, you can choose to receive alerts for SCTE-35 markers by selecting the **Enable SCTE-35 alerts** checkbox.
:::
:::WorkflowBlockItem
In the **Public Output** field, if you would like to allow access to the stream directly through a supported player, select the **Allow** checkbox.
:::
:::WorkflowBlockItem
If you selected the **Allow** checkbox, then enter a password in the **Password **field to authenticate access to the stream.
:::
::::WorkflowBlockItem
Under **Content Analysis** select one of the following options:
- **Full** - select this option if you would like to enable full Content Analysis (CQA), including analysis of the stream's audio and video content, including audio levels, audio silence detection, frozen video detection, and more.
- **TR101 Only** - select this option to perform TR101 analysis only (without video and audio content analysis). The analysis can be used to check the integrity of the TS and the most important elements of the stream. The analysis includes priority 1 and 2. To learn more about TR101 analysis see [TR 101 290 Technical Report](http://www.etsi.org/deliver/etsi_tr/101200_101299/101290/01.03.01_60/tr_101290v010301p.pdf).
- **None** - no content analysis is enabled.
:::hint{type="info"}
It is generally recommended to enable full Content Analysis unless it is causing technical problems. If Content Analysis is disabled, the system won't detect errors in the video and audio content of the stream and won't generate warnings for such events.
:::
::::
:::WorkflowBlockItem
If you would like to disable the Source thumbnail from appearing in the Sources list and other places, select the **Hide Thumbnail** option. Disabling thumbnail may improve system performance.
:::
::::WorkflowBlockItem
If you would like to monitor CEA-608 closed captions, select **Monitor CEA-608 **checkbox**.**
:::hint{type="info"}
Monitoring CEA-608 Closed Captions requires using a version 14.4 or newer Broadcaster.
:::
If you would like to monitor CEA-708 closed captions, select **Monitor CEA-708 **checkbox**.**
:::hint{type="info"}
Monitoring CEA-708 Closed Captions requires using a version 14.4 or newer Broadcaster.
:::
::::
::::WorkflowBlockItem
If you would like to disable auto-pull, select the **Disable Auto-Pull** checkbox.
:::hint{type="info"}
Disabling Auto-Pull will lock Channels using this Source to the Source's Ingest Cluster and Targets to the Source's current active Broadcaster. This setting only applies to Pass-Through Channels.
:::
::::
:::WorkflowBlockItem
If Auto-Pull is *enabled*, in the **Auto-Pull Latency \[ms]** field, specify the maximum latency for auto-pull actions. The Broadcaster will update the latency as required, by using the maximal defined latency and then reducing the latency gradually. (Default: 1000 ms)
:::
::::WorkflowBlockItem
In the **WebRTC Playback** section, select the desired playback method.
:::hint{type="info"}
WebRTC enables you to monitor the stream via web browsers and mobile applications with real-time communication (RTC). WebRTC needs to be activated independently for each Source in ZEN Master (by default it is disabled).
:::
Select one of the following options:
- **Disabled **- users will not be able to view this Source using WebRTC (default)
- **Pass-Through** - passes the stream through to WebRTC without transcoding. This option *can only be used *if the input stream is already in a WebRTC compliant format (video - H.264 codec with *Baseline *or *Main *profile and no B frames, Audio - Opus codec).
- **Auto **- ZEN Master automatically transcodes the stream using the optimal profile for each specific user. In this option Zixi Broadcaster will decode the video, transforming it into RAW frames, which will be passed to the WebRTC library, where it will be re-encoded for each individual user.
:::hint{type="info"}
Best quality. However, if monitored by multiple users this can consume extensive resources.
:::
- **1080p/720p/480p/360p** - ZEN Master transcodes the stream to a WebRTC compliant profile with the specified resolution. The transcoding is done by Zixi Broadcaster's transcoder.
:::hint{type="info"}
This method requires a Zixi Broadcaster with X264 or Nvidia for transcoding. This method allows many users to monitor the stream without encoding separately for each individual user, which saves CPU capacity. Since there is only one stream version, it is recommended to encode to a low resolution and low bitrate so that the stream will be viewable by all users monitoring the stream.
:::
::::
:::WorkflowBlockItem
In the **Initial State** section, select the **Disabled** checkbox if you would like to disable this Source upon initial configuration.
:::
::::WorkflowBlockItem
Select the **Muted** checkbox if you would like to disable error/recovery notifications for this Source upon initial configuration.
:::hint{type="info"}
You can Enable/Unmute the Source at any time.
:::

:::WorkflowBlockItem
If you would like to adjust the advanced settings, click **Advanced**.
The **Advanced** settings fields are displayed:
:::
:::WorkflowBlockItem
If you would like to track usage for this Source, enter your **Billing Code** details. See [Billing Codes](docId\:lalXJ_N928TeGCPDpBirJ).
:::
:::WorkflowBlockItem
In the **Auto Pull MTU** field, specify the maximum transmission unit (largest data packet that a network-connected device will accept) in bytes for the Auto Pull.
:::
:::WorkflowBlockItem
To set the detection of frozen video, in the **Frozen Video Minimal Duration** field, specify the default minimal duration in seconds of frozen video after which the Broadcaster will trigger a Frozen video alert. Default: 10 seconds. This setting is supported for Broadcaster version 16.3 and higher.
:::
:::WorkflowBlockItem
To set the detection of blank video, in the **Blank Video Minimal Duration** field, specify the default minimal duration in seconds of blank video after which the Broadcaster will trigger a Blank video alert. Default: 10 seconds. This setting is supported for Broadcaster version 16.3 and higher.
