# Enterprise Bandwidth Manager
Enterprise Bandwidth Manager (EBM) sets a maximum upload bandwidth cap for all cameras at a site. The cap applies to cloud-bound camera traffic, so you can protect WAN performance while cameras stay online.
{% hint style="danger" %}
You need Org Admins or Site Admins permissions to manage the Enterprise Bandwidth Manager.

### Allowlist domains for EBM
The following hostnames must be allowlisted for EBM. Use port 443 on TCP and UDP. For broader camera connectivity, see [Camera Network Settings](https://help.verkada.com/verkada-cameras/configuration/camera-network-settings).
{% hint style="info" %}
\*.vnetcap.control.verkada.com
\*.vstream.vnetcap.control.verkada.com
\*.vosprey.vnetcap.control.verkada.com
\*.vsubmit.vnetcap.control.verkada.com
\*.vproxy.vnetcap.control.verkada.com
\*.vprovision.vnetcap.control.verkada.com

## Overview
The Enterprise Bandwidth Management (EBM) service runs in the Verkada cloud and does not require any additional applications or on-site hardware. It monitors all upstream traffic at each site where it is enabled to ensure bandwidth usage stays within configured limits.
**For upstream bandwidth calculations, EBM accounts for two types of traffic:**
* Thumbnail and people/vehicle analytics traffic, which remain constant
* Cloud video streaming traffic, which occurs on demand
Archive creation and [cloud backup](https://help.verkada.com/verkada-cameras/video-streaming-and-sharing/view-historical-footage/cloud-backup) uploads from the site are also included in upstream calculations and are limited when EBM is enabled.
{% hint style="warning" %}
EBM automatically accounts for bandwidth used by thumbnails and analytics and throttles this traffic as site upstream usage approaches the configured bandwidth limit.
{% endhint %}
#### Cloud video stream evaluation
**Once a new cloud video stream is initiated, EBM calculates:**
* Whether sufficient upstream bandwidth is available at the site
* If sufficient bandwidth is available, it initiates the stream and makes it playable
**If a new stream would exceed the configured site bandwidth limit, EBM:**
* Denies the stream request
* Displays an error message to the user
* Allows playback only after sufficient bandwidth becomes available
{% hint style="warning" %}
When a stream of recorded video is started, it’s expected to see a spike greater than the camera bitrate, because video is prefetched for an optimal viewing experience.
{% endhint %}
{% hint style="success" %}
Both live and historical local video streams are exempt from EBM because their traffic stays entirely on the LAN. See [Local streaming on Verkada cameras](https://help.verkada.com/verkada-cameras/video-streaming-and-sharing/live-streaming/local-streaming-on-verkada-cameras) for more information.

## Set the bandwidth limit
{% hint style="warning" %}
When EBM is enabled, video playback is limited to 1× speed.
{% endhint %}
{% stepper %}
{% step %}
**In Verkada Command, go to All Products > Cameras.**
{% endstep %}
{% step %}
**Next to the site name, click**  **and select Set Bandwidth Limit.**
Alternatively, on the Sites page, open Manage Sites and use the options under Create Sites to reach the same control.
{% hint style="warning" %}
The first time you open EBM for a site, the bandwidth graph may take a few seconds to appear.
{% endhint %}
{% endstep %}
{% step %}
**Select Set Limit and enter the limit in Mbps.**
{% hint style="warning" %}
The limit can take up to 10 seconds to apply after you save. After you move a camera to the site, allow up to 10 minutes for behavior to fully align with the new site.
{% endhint %}
{% endstep %}
{% step %}
**At the top right, click X to close.**
{% endstep %}
{% endstepper %}

## Determine bandwidth consumption
To monitor uplink usage, EBM graphs uplink usage in real time. You can access this graph while assessing bandwidth limits.
{% hint style="info" %}
For per-camera resting and streaming optimization (not a site-wide cap), see [Optimize Low Bandwidth Mode](https://help.verkada.com/verkada-cameras/configuration/camera-network-settings/optimize-low-bandwidth-mode).
{% endhint %}
{% stepper %}
{% step %}
**In Verkada Command, go to All Products > Cameras.**
{% endstep %}
{% step %}
**Next to the site name, click**  **and select Set Bandwidth Limit.**
Use this graph to determine how much bandwidth users on the site use at a given time, gain insight into uplink usage statistics, and determine optimal bandwidth usage.
{% endstep %}
{% endstepper %}
By default, thumbnails are enabled, while analytics features can be toggled on or off in the camera settings. EBM considers a fixed bandwidth consumption for each feature.
| | |
| ----------- | ------------------------- |
| **Feature** | **Bandwidth consumption** |
| Thumbnails | 40 kbps |
| Analytics | 400 kbps |
For stream bandwidth consumption, use this table as a quick reference:
| | | |
| --------------------- | --------------------- | ------------------------- |
| **Camera resolution** | **Stream resolution** | **Bandwidth consumption** |
| 4K | HQ | Up to 5 Mbps |
| 4K | SQ | 0.6 Mbps |
| Non-4K | HQ | Up to 3 Mbps |
| Non-4K | SQ | 0.3 Mbps |
{% hint style="info" %}
See [Bandwidth Consumption & Uplink Requirements for Video](https://help.verkada.com/verkada-cameras/installation/camera-specs/bandwidth-consumption-uplink-requirements-for-video) for more model-specific information.
{% endhint %}

## Terminate streams
You can manage active camera streams at a site, which is especially useful during investigations. If bandwidth approaches its limit or you need to prioritize network resources for critical operations, you can proactively terminate active video streams.
{% stepper %}
{% step %}
**In Verkada Command, go to All Products > Cameras.**
{% endstep %}
{% step %}
**Identify the site with active streams.**
{% endstep %}
{% step %}
**Click**  **and select Set Bandwidth Limit.**
{% endstep %}
{% step %}
**Configure a bandwidth limit if there is none.**
{% hint style="warning" %}
The first time you open EBM for a site, the bandwidth graph may take a few seconds to appear.
{% endhint %}
{% endstep %}
{% step %}
**Review the list of active streams and select the stream(s) you want to terminate.**
{% endstep %}
{% step %}
**At the top right, click X to close.**
{% endstep %}
{% endstepper %}
